Multiple stack-based buffer overflows in the Cisco WebEx Recording Format (WRF) and Advanced Recording Format (ARF) Players T27LB before SP21 EP3 and T27LC before SP22 allow remote attackers to execute arbitrary code via a crafted (1) .wrf or (2) .arf file, related to use of a function pointer in a callback mechanism. Cisco WebEx is a web conferencing solution. Cisco WebEx provides record format files for storing WebEX meeting notes, and WRF Player is an application for playing back and editing WRF files (files end with a .wrf extension). This vulnerability can be triggered by publishing a .wrf video file in a conference room: .text:6070C272 loc_6070C272: ; CODE XREF: sub_6070C050+255j.text:6070C272 test esi, esi.text:6070C274 jnz short loc_6070C28F.text:6070C276 push ebx.text :6070C277 call dword ptr [ebp+0Ch] ; call to function pointer on the stack.text:6070C27A add esp, 4.text:6070C27D test al, al.text:6070C27F jz loc_6070C374.text:6070C285 mov edi, [ebp+ 0].text:6070C288 mov esi, [ebp+4].text:6070C28B mov eax, [esp+0D98h+var_D80].text:6070C28F.text:6070C28F loc_6070C28F: ; CODE XREF: sub_6070C050+224j.text:6070C28F mov Cl, [edi] ; cl can be controlled, it is read from the malicious .wrf file.text:6070C291 dec esi.text:6070C292 mov [esp+eax+0D 98h+var_C8C], cl ; this mov overflows the stack with user controlled values.text:6070C299 mov ecx, [esp+0D98h+var_D84].text:6070C29D inc edi.text:6070C29E inc eax.text:6070C29F cmp eax, ecx .text:6070C2A1 mov [esp+0D98h+var_D80], eax.text:6070C2A5 jl short loc_6070C272. Cisco WebEx is prone to multiple remote buffer-overflow vulnerabilities because it fails to perform adequate boundary-checks on user-supplied data. An attacker can exploit these issues to execute arbitrary code with the privileges of the affected application. Failed exploit attempts will result in a denial-of-service condition. The Cisco WebEx Players are applications that are used to play back WebEx meeting recordings that have been recorded on the computer of an on-line meeting attendee. The players can be automatically installed when the user accesses a recording file that is hosted on a WebEx server. The player can also be manually installed for offline playback after downloading the application from www.webex.com If the WebEx recording player was automatically installed, it will be automatically upgraded to the latest, non-vulnerable version when users access a recording file that is hosted on a WebEx server. If the WebEx recording player was manually installed, users will need to manually install a new version of the player after downloading the latest version from www.webex.com Cisco has released free software updates that address these vulnerabilities. Affected Products ================= Vulnerable Products +------------------ The vulnerabilities disclosed in this advisory affect the Cisco WebEx recording players. Microsoft Windows, Apple Mac OS X, and Linux versions of the player are all affected. Affected versions of the players are those prior to client builds T27LC SP22 and T27LB SP21 EP3. Customers who have contractual agreements that prevent WebEx from automatically upgrading a recording player to the latest version should contact their account manager to determine upgrade options. To determine whether a Cisco WebEx server is running an affected version of the WebEx client build, users can log in to their Cisco WebEx server and go to the Support > Downloads section. The version of the WebEx client build will be displayed on the right side of the page under "About Support Center." See "Software Versions and Fixes" for details. Details ======= The WebEx meeting service is a hosted multimedia conferencing solution that is managed and maintained by Cisco WebEx. The WRF and ARF file formats are used to store WebEx meeting recordings that have been recorded on the computer of an on-line meeting attendee. The recording players can be automatically installed when the user accesses a recording file that is hosted on a WebEx server (for stream playback mode). The recording players can also be manually installed after downloading the application from www.webex.com/downloadplayer.html to play back recording files locally (for offline playback mode). Multiple buffer overflow vulnerabilities exist in the WRF and ARF players. The vulnerabilities may lead to a crash of the player application or, in some cases, remote code execution could occur. To exploit one of these vulnerabilities, the player application would need to open a malicious WRF or ARF file. An attacker may be able to accomplish this exploit by providing the malicious recording file directly to users (for example, by using e-mail) or by directing a user to a malicious web page. These vulnerabilities have been assigned the following Common Vulnerabilities and Exposures (CVE) identifiers: * CVE-2010-3269 * CVE-2010-3041 * CVE-2010-3042 * CVE-2010-3043 * CVE-2010-3044 Vulnerability Scoring Details Cisco has provided scores for the vulnerabilities in this advisory based on the Common Vulnerability Scoring System (CVSS). The CVSS scoring in this Security Advisory is done in accordance with CVSS version 2.0. CVSS is a standards-based scoring method that conveys vulnerability severity and helps determine urgency and priority of response. Cisco has provided a base and temporal score. Customers can then compute environmental scores to assist in determining the impact of the vulnerability in individual networks. Cisco has provided an FAQ to answer additional questions regarding CVSS at: http://www.cisco.com/web/about/security/intelligence/cvss-qandas.html Cisco has also provided a CVSS calculator to help compute the environmental impact for individual networks at: http://intellishield.cisco.com/security/alertmanager/cvss * Multiple Cisco WebEx Player Buffer Overflow Vulnerabilities CVSS Base Score - 9.3 Access Vector - Network Access Complexity - Medium Authentication - None Confidentiality Impact - Complete Integrity Impact - Complete Availability Impact - Complete CVSS Temporal Score - 7.7 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed Impact ====== Successful exploitation of the vulnerabilities described in this document could result in a crash of the Cisco WebEx ARF Player or WRF Player application and, in some cases, allow a remote attacker to execute arbitrary code on the system with the privileges of the user who is running the recording player application. Software Versions and Fixes =========================== When considering software upgrades, also consult http://www.cisco.com/go/psirt and any subsequent advisories to determine exposure and a complete upgrade solution. These vulnerabilities are first fixed in T27LC SP22 and T27LB SP21 EP3. The client build will be determined after the software is deployed. The client build is listed in the Support > Downloads section of the WebEx page after a user authenticates. WebEx bug fixes are cumulative in a major release. For example, if release 27.22SP.0 is fixed, release 27.22SP.1 will also have the software fix. If a recording player was automatically installed, it will be automatically upgraded to the latest, nonvulnerable version when users access a recording file that is hosted on a WebEx server. If a WebEx recording player was manually installed, users will need to manually install a new version of the player after downloading the latest version from www.webex.com/downloadplayer.html Workarounds =========== There are no workarounds for the vulnerabilities disclosed in this advisory.

All rights reserved. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Core Security Technologies - Corelabs Advisory http://corelabs.coresecurity.com/ Cisco WebEx .atp and .wrf Overflow Vulnerabilities 1. *Advisory Information* Title: Cisco WebEx .atp and .wrf Overflow Vulnerabilities Advisory ID: CORE-2010-1001 Advisory URL: [http://www.coresecurity.com/content/webex-atp-and-wrf-overflow-vulnerabilities] Date published: 2011-01-31 Date of last update: 2011-01-31 Vendors contacted: Cisco Release mode: Coordinated release 2. *Vulnerability Information* Class: Stack-based Buffer Overflow [CWE-121], Stack-based Buffer Overflow [CWE-121] Impact: Code execution Remotely Exploitable: Yes (client-side) Locally Exploitable: No CVE Name: CVE-2010-3269, CVE-2010-3270 Bugtraq ID: N/A 3. *Vulnerability Description* There are stack overflows on WebEx [1] that can be exploited by sending maliciously crafted .atp and .wrf files to a vulnerable WebEx user. When opened, these files trigger a reliably exploitable stack based buffer overflow. In the .atp case an exception handler can be overwritten on the stack, and most registers can be trivially overwritten. 4. *Vulnerable packages* . Contact Cisco for a list of vulnerable versions. 5. *Non-vulnerable packages* . Contact Cisco. 6. *Vendor Information, Solutions and Workarounds* All clients of WebEx Meeting Center should now be running a patched version according to Cisco. A non-vulnerable version of WebEx Player should be available at [http://www.webex.com/downloadplayer.html]. 7. *Credits* These vulnerabilities were discovered and researched by Federico Muttis, Sebastian Tello and Manuel Muradas from Core Security Technologies during Bugweek 2010 as part of the "Cisco Baby Cisco!" team [2]. The publication of this advisory was coordinated by Pedro Varangot. 8. *Technical Description* 8.1. *WebEx Player .wrf Buffer Overflow [CVE-2010-3269]* WebEx Player can be used to playback recordings of WebEx sessions. These recordings can be stored using the .wrf closed and undocumented file format. This vulnerability can also be exploited by publishing a .wrf video file in a meeting, resulting in the compromise of the meeting's participants. *WebEx Meeting Center .atp Buffer Overflow [CVE-2010-3270]* WebEx Meeting Center allows polls to be conducted between all participants of a WebEx session. By serving a specially crafted .atp file (used for conducting polls) the meeting host can then abruptly disconnect from the server, and when another client becomes host and tries to share the .atp file with the other clients arbitrary code execution is possible on his workstation. If his connection to the server is then severed by a malicious payload, the .atp file will be cycled to the next connected client. We developed trivial examples that take control of EIP using arbitrary characters. 9. *Report Timeline* . 2010-10-04: Core Security Technologies contacts Cisco PSIRT using their provided PGP key notifying them of the vulnerabilities and sending an advisory draft, a proof of concept for the WebEx Player vulnerability, and a proof of concept for the Meeting Center vulnerability including details of how to reproduce both vulnerabilities, and details about the behaviour of the PoC for the Player vulnerability on Windows XP SP2 (which overwrites EIP with 0x41414141 on that platform). October 18th 2010 (a two weeks timeframe) is set as a potential release date for the advisory. 2010-10-05: Cisco PSIRT contacts Core stating that their development team is out of the office till Friday October 8th. November 15th 2010 is mentioned as an estimated release date for a fix. 2010-10-05: Core replies to Cisco PSIRT postponing the release date of this advisory for one week, to Monday October 25th, in order to contemplate the fact that Cisco's development team is away from office for the week. Further changes to the release date will be made after receiving technical feedback. November the 15th is mentioned to be a possible date to settle on. 2010-10-11: Cisco PSIRT replies acknowledging "an exception in WebEx player" but that doesn't overwrite EIP as Core Security Technologies indicated. Cisco notifies that they were not able to reproduce the crash in WebEx Meeting Center. Cisco PSIRT also asks for more detailed information about the version of WebEx Player used. 2010-10-12: Core sends the requested information, also attaching new proof of concept exploits for the WebEx Player vulnerability (that now executes code and launches "calc.exe"), and further details about the steps needed to reproduce the WebEx Meeting Center crash. Details about the system where the proof of concept for the WebEx Player vulnerability was run are asked. Details about the "exception" are also asked, specially noting that if other registers are overwritten this should be considered as a vulnerability that would possibly lead to reliable code execution even if EIP was not modified (as noted by Core on the e-mail where the PoC was attached). No reply is received to this e-mail. 2010-10-19: Core resends the previous e-mail asking for news about reproduction of the vulnerability on Cisco's side and asking if there was any problem in the reception or interpretation of the last communication. No reply is received to this e-mail. 2010-10-28: Core Security Technologies resends the last e-mail, unilaterally rescheduling the publication of this advisory to November 8th 2010, which is closer to Cisco's initial estimation for the release of a fix. Core states its willingness to reschedule this publication date but only under firm commitment from Cisco to working seriously towards fixing this issue in a scheduled timeframe. An updated advisory draft is attached which includes an updated timeline. 2010-10-30: Cisco PSIRT replies acknowledging the vulnerability, stating that they were able to reproduce code execution results in the currently released version of WebEx, and a crash in their current development version. Cisco also states that there is not information yet from their development team about when a fix for this vulnerability will be released. 2010-11-09: Core replies offering more technical details about exploitation if they are needed, and reminding Cisco that the crash in their development version may also be exploitable even if the current proof of concept exploit only crashes it. The publication date for this advisory is rescheduled to November 22nd 2010. Core states that they will like to schedule a firm date for the release of information about this vulnerability to the public and hence would like to get more information from Cisco about the schedule for the release of a fix. 2010-11-15: Cisco states that fixed code will be deployed in mid-December, but since WebEx Meeting Center runs on a SaaS environment it takes about four or five weeks for all clients to be running the latest version of the code. 2010-12-06: Cisco contacts Core since no reply was received in the past two weeks, and clarifies that a fix will be deployed on December 15th and should be done on January 11th 2011. 2010-12-06: Core states that they believe this advisory should be released as soon as the fix is deployed, since diffing the WebEx binary on the client side gives full details about the WebEx Meeting Center vulnerability to an average skilled reverse engineer. Core schedules the publication of this advisory to December 15th 2010. 2010-12-07: Cisco contacts Core stating that releasing details about this vulnerability would endanger customers, since there is no action they can take to protect themselves because the responsibility of upgrading the code ran by the customer falls on Cisco. Cisco mentions that "many of these customers are probably shared between Cisco and Core Security". 2010-12-10: Cisco contacts Core stating that they have just discovered the WebEx Meeting Center Vulnerability affects a new set of customers that where not accounted for originally. These are customers running T27SP21 that can not be upgraded to SP22. An emergency patch will be released for SP21 in January 2011, and this sets back the date when all clients should be running an updated version to the "end of January, beginning of February." . 2010-12-14: Core proposes to split this advisory into two different advisories to better accommodate the WebEx Meeting Center SaaS release cycle. On one advisory, the .wrf client side vulnerability would be described, and the other would be dedicated to the WebEx Meeting Center vulnerability that may compromise a meeting's host computer. Core believes this mitigates the risk in a more effective way, since clients can update WebEx Player by themselves on December 15th (the date when Cisco stated the fixed version would be released) and no details of the Meeting Center vulnerability would be released until all clients are running an updated version. 2010-12-15: Cisco states they wouldn't like the advisory to be splitted, and that they prefer Core Security Technologies to go ahead and release information about both vulnerabilities. 2010-12-15: Core states that they prefer to release two advisories because these are two different bugs, in two pieces of software, each one of them with a differently working update channel determined by the vendor. Core also informs Cisco that the download link for WebEx Player points to a vulnerable version as of today, and asks Cisco to clarify what date they meant as mid-December, since Core would like to know when a fixed version of WebEx Player will be available for download to be able to publish the WebEx Player vulnerability. 2010-12-16: Cisco replies saying that releasing two advisories seems like a good plan to them. Cisco also states that since many of their customers observe a lockdown policy during the holidays season, they take a "don't upgrade" policy of their own until Monday January 10th, 2011. That is the reason why the download link of WebEx Player has not been changed yet. 2011-01-10: Core states that they are ready to release this advisory on January 11th, and that releasing two separate advisories seems pointless now because the release date of both would be very similar, and the original idea was to mitigate the risk posed by the .wrf vulnerability. Core also states that they are reviewing the best course of action to take with the issue regarding clients running the old version of WebEx (T27SP21) that according to Cisco are unable to upgrade to SP22 since this was not accounted for previously. 2011-01-13: Core states that since they have committed previously to release the advisory taking into account Cisco's consideration about their SaaS patch deploy model, when factoring the issue of clients running the SP21 version of Meeting Center scheduled by Cisco for emergency update on January, a release date of January the 31st seems reasonable. This date should be taken as final and Core Security Technologies believes it takes into account all information given by Cisco about SaaS updating timeframes. If this is not the case Cisco is asked to rectify ASAP. 2011-01-14: Cisco confirms that the timeframe (publishing both vulnerabilities on January 31st) works for them. 2011-01-31: The advisory CORE-2010-1001 is published. 10. *References* [1] [http://www.webex.com/] [2] [http://corelabs.coresecurity.com/index.php?module=Wiki&action=view&type=project&name=Bugweek] 11. *About CoreLabs* CoreLabs, the research center of Core Security Technologies, is charged with anticipating the future needs and requirements for information security technologies.

Multiple buffer overflows in the Cisco WebEx Recording Format (WRF) and Advanced Recording Format (ARF) Players T27LB before SP21 EP3 and T27LC before SP22 allow remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted (1) .wrf or (2) .arf file, related to atas32.dll, a different vulnerability than CVE-2010-3041, CVE-2010-3042, and CVE-2010-3043. Cisco WebEx is prone to multiple remote buffer-overflow vulnerabilities because it fails to perform adequate boundary-checks on user-supplied data. Failed exploit attempts will result in a denial-of-service condition. The Cisco WebEx Players are applications that are used to play back WebEx meeting recordings that have been recorded on the computer of an on-line meeting attendee. The players can be automatically installed when the user accesses a recording file that is hosted on a WebEx server. The player can also be manually installed for offline playback after downloading the application from www.webex.com If the WebEx recording player was automatically installed, it will be automatically upgraded to the latest, non-vulnerable version when users access a recording file that is hosted on a WebEx server. If the WebEx recording player was manually installed, users will need to manually install a new version of the player after downloading the latest version from www.webex.com Cisco has released free software updates that address these vulnerabilities. This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20110201-webex.shtml. Affected Products ================= Vulnerable Products +------------------ The vulnerabilities disclosed in this advisory affect the Cisco WebEx recording players. Microsoft Windows, Apple Mac OS X, and Linux versions of the player are all affected. Affected versions of the players are those prior to client builds T27LC SP22 and T27LB SP21 EP3. Customers who have contractual agreements that prevent WebEx from automatically upgrading a recording player to the latest version should contact their account manager to determine upgrade options. To determine whether a Cisco WebEx server is running an affected version of the WebEx client build, users can log in to their Cisco WebEx server and go to the Support > Downloads section. The version of the WebEx client build will be displayed on the right side of the page under "About Support Center." See "Software Versions and Fixes" for details. Cisco recommends that users upgrade to the most current version of the player that is available from www.webex.com/downloadplayer.html Products Confirmed Not Vulnerable +-------------------------------- No other Cisco products are currently known to be affected by these vulnerabilities. Details ======= The WebEx meeting service is a hosted multimedia conferencing solution that is managed and maintained by Cisco WebEx. The WRF and ARF file formats are used to store WebEx meeting recordings that have been recorded on the computer of an on-line meeting attendee. The players are applications that are used to play back and edit recording files (files with .wrf and .arf extensions). The recording players can be automatically installed when the user accesses a recording file that is hosted on a WebEx server (for stream playback mode). The recording players can also be manually installed after downloading the application from www.webex.com/downloadplayer.html to play back recording files locally (for offline playback mode). Multiple buffer overflow vulnerabilities exist in the WRF and ARF players. The vulnerabilities may lead to a crash of the player application or, in some cases, remote code execution could occur. To exploit one of these vulnerabilities, the player application would need to open a malicious WRF or ARF file. An attacker may be able to accomplish this exploit by providing the malicious recording file directly to users (for example, by using e-mail) or by directing a user to a malicious web page. The vulnerability cannot be triggered by users who are attending a WebEx meeting.

Stack-based buffer overflow in Cisco WebEx Meeting Center T27LB before SP21 EP3 and T27LC before SP22 allows user-assisted remote authenticated users to execute arbitrary code by providing a crafted .atp file and then disconnecting from a meeting. NOTE: since this is a site-specific issue with no expected action for consumers, it might be REJECTed. Since this site has been identified, no general user action is required. Cisco WebEx is a web conferencing solution. There is a stack overflow in the .atp file format provided by Cisco WebEx. The function pointers in the stack can be overwritten, and the DEP and ASLR are disabled, resulting in very stable use of the code. Cisco WebEx is prone to a remote code-execution vulnerability because the application fails to perform adequate boundary checks on user-supplied data. An attacker can exploit this issue to execute arbitrary code with the privileges of the affected application. Failed exploit attempts will result in a denial-of-service condition. WebEx is the world's largest provider of network communication services, providing carrier-class network conferencing solutions. Currently WebEx has been acquired by Cisco. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Core Security Technologies - Corelabs Advisory http://corelabs.coresecurity.com/ Cisco WebEx .atp and .wrf Overflow Vulnerabilities 1. *Advisory Information* Title: Cisco WebEx .atp and .wrf Overflow Vulnerabilities Advisory ID: CORE-2010-1001 Advisory URL: [http://www.coresecurity.com/content/webex-atp-and-wrf-overflow-vulnerabilities] Date published: 2011-01-31 Date of last update: 2011-01-31 Vendors contacted: Cisco Release mode: Coordinated release 2. *Vulnerability Description* There are stack overflows on WebEx [1] that can be exploited by sending maliciously crafted .atp and .wrf files to a vulnerable WebEx user. When opened, these files trigger a reliably exploitable stack based buffer overflow. In the .atp case an exception handler can be overwritten on the stack, and most registers can be trivially overwritten. 4. *Vulnerable packages* . Contact Cisco for a list of vulnerable versions. 5. *Non-vulnerable packages* . Contact Cisco. 6. *Vendor Information, Solutions and Workarounds* All clients of WebEx Meeting Center should now be running a patched version according to Cisco. A non-vulnerable version of WebEx Player should be available at [http://www.webex.com/downloadplayer.html]. 7. *Credits* These vulnerabilities were discovered and researched by Federico Muttis, Sebastian Tello and Manuel Muradas from Core Security Technologies during Bugweek 2010 as part of the "Cisco Baby Cisco!" team [2]. The publication of this advisory was coordinated by Pedro Varangot. 8. *Technical Description* 8.1. *WebEx Player .wrf Buffer Overflow [CVE-2010-3269]* WebEx Player can be used to playback recordings of WebEx sessions. These recordings can be stored using the .wrf closed and undocumented file format. This vulnerability can also be exploited by publishing a .wrf video file in a meeting, resulting in the compromise of the meeting's participants. /----- .text:6070C272 loc_6070C272: ; CODE XREF: sub_6070C050+255j .text:6070C272 test esi, esi .text:6070C274 jnz short loc_6070C28F .text:6070C276 push ebx .text:6070C277 call dword ptr [ebp+0Ch] ; call to function pointer on the stack .text:6070C27A add esp, 4 .text:6070C27D test al, al .text:6070C27F jz loc_6070C374 .text:6070C285 mov edi, [ebp+0] .text:6070C288 mov esi, [ebp+4] .text:6070C28B mov eax, [esp+0D98h+var_D80] .text:6070C28F .text:6070C28F loc_6070C28F: ; CODE XREF: sub_6070C050+224j .text:6070C28F mov cl, [edi] ; cl can be controlled, it is read from the malicious .wrf file .text:6070C291 dec esi .text:6070C292 mov [esp+eax+0D98h+var_C8C], cl ; this mov overflows the stack with user controlled values .text:6070C299 mov ecx, [esp+0D98h+var_D84] .text:6070C29D inc edi .text:6070C29E inc eax .text:6070C29F cmp eax, ecx .text:6070C2A1 mov [esp+0D98h+var_D80], eax .text:6070C2A5 jl short loc_6070C272 - -----/ 8.2.

We developed trivial examples that take control of EIP using arbitrary characters. 9. *Report Timeline* . 2010-10-04: Core Security Technologies contacts Cisco PSIRT using their provided PGP key notifying them of the vulnerabilities and sending an advisory draft, a proof of concept for the WebEx Player vulnerability, and a proof of concept for the Meeting Center vulnerability including details of how to reproduce both vulnerabilities, and details about the behaviour of the PoC for the Player vulnerability on Windows XP SP2 (which overwrites EIP with 0x41414141 on that platform). October 18th 2010 (a two weeks timeframe) is set as a potential release date for the advisory. 2010-10-05: Cisco PSIRT contacts Core stating that their development team is out of the office till Friday October 8th. November 15th 2010 is mentioned as an estimated release date for a fix. 2010-10-05: Core replies to Cisco PSIRT postponing the release date of this advisory for one week, to Monday October 25th, in order to contemplate the fact that Cisco's development team is away from office for the week. Further changes to the release date will be made after receiving technical feedback. November the 15th is mentioned to be a possible date to settle on. 2010-10-11: Cisco PSIRT replies acknowledging "an exception in WebEx player" but that doesn't overwrite EIP as Core Security Technologies indicated. Cisco PSIRT also asks for more detailed information about the version of WebEx Player used. 2010-10-12: Core sends the requested information, also attaching new proof of concept exploits for the WebEx Player vulnerability (that now executes code and launches "calc.exe"), and further details about the steps needed to reproduce the WebEx Meeting Center crash. Details about the system where the proof of concept for the WebEx Player vulnerability was run are asked. Details about the "exception" are also asked, specially noting that if other registers are overwritten this should be considered as a vulnerability that would possibly lead to reliable code execution even if EIP was not modified (as noted by Core on the e-mail where the PoC was attached). No reply is received to this e-mail. 2010-10-19: Core resends the previous e-mail asking for news about reproduction of the vulnerability on Cisco's side and asking if there was any problem in the reception or interpretation of the last communication. No reply is received to this e-mail. 2010-10-28: Core Security Technologies resends the last e-mail, unilaterally rescheduling the publication of this advisory to November 8th 2010, which is closer to Cisco's initial estimation for the release of a fix. Core states its willingness to reschedule this publication date but only under firm commitment from Cisco to working seriously towards fixing this issue in a scheduled timeframe. An updated advisory draft is attached which includes an updated timeline. 2010-10-30: Cisco PSIRT replies acknowledging the vulnerability, stating that they were able to reproduce code execution results in the currently released version of WebEx, and a crash in their current development version. Cisco also states that there is not information yet from their development team about when a fix for this vulnerability will be released. 2010-11-09: Core replies offering more technical details about exploitation if they are needed, and reminding Cisco that the crash in their development version may also be exploitable even if the current proof of concept exploit only crashes it. The publication date for this advisory is rescheduled to November 22nd 2010. Core states that they will like to schedule a firm date for the release of information about this vulnerability to the public and hence would like to get more information from Cisco about the schedule for the release of a fix. 2010-11-15: Cisco states that fixed code will be deployed in mid-December, but since WebEx Meeting Center runs on a SaaS environment it takes about four or five weeks for all clients to be running the latest version of the code. 2010-12-06: Cisco contacts Core since no reply was received in the past two weeks, and clarifies that a fix will be deployed on December 15th and should be done on January 11th 2011. 2010-12-06: Core states that they believe this advisory should be released as soon as the fix is deployed, since diffing the WebEx binary on the client side gives full details about the WebEx Meeting Center vulnerability to an average skilled reverse engineer. Core schedules the publication of this advisory to December 15th 2010. 2010-12-07: Cisco contacts Core stating that releasing details about this vulnerability would endanger customers, since there is no action they can take to protect themselves because the responsibility of upgrading the code ran by the customer falls on Cisco. Cisco mentions that "many of these customers are probably shared between Cisco and Core Security". 2010-12-10: Cisco contacts Core stating that they have just discovered the WebEx Meeting Center Vulnerability affects a new set of customers that where not accounted for originally. These are customers running T27SP21 that can not be upgraded to SP22. An emergency patch will be released for SP21 in January 2011, and this sets back the date when all clients should be running an updated version to the "end of January, beginning of February." . 2010-12-14: Core proposes to split this advisory into two different advisories to better accommodate the WebEx Meeting Center SaaS release cycle. On one advisory, the .wrf client side vulnerability would be described, and the other would be dedicated to the WebEx Meeting Center vulnerability that may compromise a meeting's host computer. Core believes this mitigates the risk in a more effective way, since clients can update WebEx Player by themselves on December 15th (the date when Cisco stated the fixed version would be released) and no details of the Meeting Center vulnerability would be released until all clients are running an updated version. 2010-12-15: Cisco states they wouldn't like the advisory to be splitted, and that they prefer Core Security Technologies to go ahead and release information about both vulnerabilities. 2010-12-15: Core states that they prefer to release two advisories because these are two different bugs, in two pieces of software, each one of them with a differently working update channel determined by the vendor. Core also informs Cisco that the download link for WebEx Player points to a vulnerable version as of today, and asks Cisco to clarify what date they meant as mid-December, since Core would like to know when a fixed version of WebEx Player will be available for download to be able to publish the WebEx Player vulnerability. 2010-12-16: Cisco replies saying that releasing two advisories seems like a good plan to them. Cisco also states that since many of their customers observe a lockdown policy during the holidays season, they take a "don't upgrade" policy of their own until Monday January 10th, 2011. That is the reason why the download link of WebEx Player has not been changed yet. 2011-01-10: Core states that they are ready to release this advisory on January 11th, and that releasing two separate advisories seems pointless now because the release date of both would be very similar, and the original idea was to mitigate the risk posed by the .wrf vulnerability. Core also states that they are reviewing the best course of action to take with the issue regarding clients running the old version of WebEx (T27SP21) that according to Cisco are unable to upgrade to SP22 since this was not accounted for previously. 2011-01-13: Core states that since they have committed previously to release the advisory taking into account Cisco's consideration about their SaaS patch deploy model, when factoring the issue of clients running the SP21 version of Meeting Center scheduled by Cisco for emergency update on January, a release date of January the 31st seems reasonable. This date should be taken as final and Core Security Technologies believes it takes into account all information given by Cisco about SaaS updating timeframes. If this is not the case Cisco is asked to rectify ASAP. 2011-01-14: Cisco confirms that the timeframe (publishing both vulnerabilities on January 31st) works for them. 2011-01-31: The advisory CORE-2010-1001 is published. 10. *References* [1] [http://www.webex.com/] [2] [http://corelabs.coresecurity.com/index.php?module=Wiki&action=view&type=project&name=Bugweek] 11. *About CoreLabs* CoreLabs, the research center of Core Security Technologies, is charged with anticipating the future needs and requirements for information security technologies.

Use-after-free vulnerability in flimflamd in flimflam in Google Chrome OS before 0.9.130.14 Beta allows user-assisted remote attackers to cause a denial of service (daemon crash) by providing the name of a hidden WiFi network that does not respond to connection attempts. Google Chrome OS is a lightweight computer operating system development program developed by Google to develop a cloud operating system dedicated to the Internet. A post-release vulnerability exists in flimflamd in flimflam prior to Google Chrome OS 0.9.130.14 Beta. Successful exploits will cause the affected application to crash, effectively denying service to legitimate users. Due to the nature of this issue, remote code execution may be possible; this has not been confirmed

Huwea HG520/HG530 are prone to a security weakness that may allow attackers to generate default WEP/WPA keys. Successfully exploiting this issue may allow attackers to generate the WEP/WPA key using the MAC address. This may lead to other attacks.

Unspecified vulnerability in Cisco IOS 12.4(24)MD before 12.4(24)MD2 on the Cisco Content Services Gateway Second Generation (aka CSG2) allows remote attackers to cause a denial of service (device hang or reload) via crafted TCP packets, aka Bug ID CSCth17178, a different vulnerability than CVE-2011-0350. The problem is Bug ID CSCth17178 It is a problem. This vulnerability CVE-2011-0350 Is a different vulnerability.Skillfully crafted by a third party TCP Service disruption via packets (DoS) There is a possibility of being put into a state. Under certain configurations this vulnerability could allow: * Customers to access sites that would normally match a billing policy to be accessed without being charged to the end customer * Customers to access sites that would normally be denied based on configured restriction policies Additionally, Cisco IOS Software Release 12.4(24)MD1 on the Cisco CSG2 contains two vulnerabilities that can be exploited by a remote, unauthenticated attacker to create a denial of service condition that prevents traffic from passing through the CSG2. A three-way handshake is not required to exploit either of these vulnerabilities. Workarounds that mitigate these vulnerabilities are not available. This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20110126-csg2.shtml. Affected Products ================= The service policy bypass vulnerability affects all versions of the Cisco IOS Software for the CSG2 prior to the first fixed release, as indicated in the "Software Versions and Fixes" section of this advisory. No other Cisco IOS Software releases are affected. Vulnerable Products +------------------ To determine the version of Cisco IOS Software that is running on the Cisco CSG2, issue the "show module" command from Cisco IOS Software on the switch on which the Cisco CSG2 module is installed to identify what modules and sub-modules are installed on the system. Cisco CSG2 runs on the Cisco Service and Application Module for IP (SAMI) card, and is identified in the following example in slot 2 via the WS-SVC-SAMI-BB-K9 identification: C7600#show module Mod Ports Card Type Model Serial No. --- ----- -------------------------------------- ------------------ ----------- 1 2 Supervisor Engine 720 (Active) WS-SUP720-3BXL JAF1226ARQS 2 1 SAMI Module (csgk9) WS-SVC-SAMI-BB-K9 SAD113906P1 4 48 CEF720 48 port 10/100/1000mb Ethernet WS-X6748-GE-TX SAL1127T6XY Mod MAC addresses Hw Fw Sw Status --- ---------------------------------- ------ ------------ ------------ ------- 1 001e.be6e.a018 to 001e.be6e.a01b 5.6 8.5(2) 12.2(33)SRC5 Ok 2 001d.45f8.f3dc to 001d.45f8.f3e3 2.1 8.7(0.22)FW1 12.4(2010040 Ok 4 001c.587a.ef20 to 001c.587a.ef4f 2.6 12.2(14r)S5 12.2(33)SRC5 Ok Mod Sub-Module Model Serial Hw Status ---- --------------------------- ------------------ ----------- ------- ------- 1 Policy Feature Card 3 WS-F6K-PFC3BXL JAF1226BNQM 1.8 Ok 1 MSFC3 Daughterboard WS-SUP720 JAF1226BNMC 3.1 Ok 2 SAMI Daughterboard 1 SAMI-DC-BB SAD114400L9 1.1 Other 2 SAMI Daughterboard 2 SAMI-DC-BB SAD114207FU 1.1 Other 4 Centralized Forwarding Card WS-F6700-CFC SAL1029VGFK 2.0 Ok Mod Online Diag Status ---- ------------------- 1 Pass 2 Pass 4 Pass C7600# After locating the correct slot, issue the "session slot <module number> processor <3-9>" command to open a console connection to the respective Cisco CSG2.

No other Cisco products are currently known to be affected by these vulnerabilities. Details ======= The Cisco Content Services Gateway - Second Generation (CSG2) provides intelligent network capabilities such as flexible policy management and billing based on deep-packet inspection, as well as subscriber and application awareness capabilities that enable mobile operators to quickly and easily offer value-added, differentiated services over their mobile data networks. The service policy bypass vulnerability affects configurations that allow end users to first access non-accounted or billed sites. After a user accesses a non-accounted site, it is possible to access other sites that are defined by a billing service policy or to access sites that may be blocked by other policies by sending specially crafted HTTP packets. This vulnerability only affects HTTP content traffic. HTTPS and other traffic types are not affected. A three-way handshake is not required to exploit either of these vulnerabilities. The vulnerabilities are triggered by TCP traffic that transits the Cisco CSG2. Vulnerability Scoring Details ============================= Cisco has provided scores for the vulnerabilities in this advisory based on the Common Vulnerability Scoring System (CVSS). The CVSS scoring in this Security Advisory is done in accordance with CVSS version 2.0. CVSS is a standards-based scoring method that conveys vulnerability severity and helps determine urgency and priority of response. Cisco has provided a base and temporal score. Customers can then compute environmental scores to assist in determining the impact of the vulnerability in individual networks. Cisco has provided an FAQ to answer additional questions regarding CVSS at: http://www.cisco.com/web/about/security/intelligence/cvss-qandas.html Cisco has also provided a CVSS calculator to help compute the environmental impact for individual networks at: http://intellishield.cisco.com/security/alertmanager/cvss * CSCtk35917 ("Service Policy Bypass Vulnerability") CVSS Base Score - 6.4 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - Partial Integrity Impact - Partial Availability Impact - None CVSS Temporal Score - 5.3 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed * CSCth41891/CSCth17178 ("Crafted TCP packet causes CSG2 to restart") CVSS Base Score - 7.8 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete CVSS Temporal Score - 6.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed Impact ====== Successful exploitation of the service policy bypass can allow customers to obtain access to sites that would normally be accounted and billed according to the billing policy without the billing policy being engaged. Additionally, customers could gain access to URLs that are configured in the Cisco CSG2 to be explicitly denied. Due to Cisco Bug ID CSCtg50821, the Cisco CSG2 may not automatically recover and may require a manual reload of the SAMI card by issuing the "hw-module module <x> reset" CLI command from the switch. Software Versions and Fixes =========================== When considering software upgrades, also consult http://www.cisco.com/go/psirt and any subsequent advisories to determine exposure and a complete upgrade solution. In all cases, customers should exercise caution to be certain the devices to be upgraded contain sufficient memory and that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, contact the Cisco Technical Assistance Center (TAC) or your contracted maintenance provider for assistance. Each row of the Cisco IOS Software table (below) names a Cisco IOS release train. If a release train is vulnerable, then the earliest possible releases that contain the fix (along with the anticipated date of availability for each, if applicable) are listed in the "First Fixed Release" column of the table.

Unspecified vulnerability in Cisco IOS 12.4(24)MD before 12.4(24)MD2 on the Cisco Content Services Gateway Second Generation (aka CSG2) allows remote attackers to cause a denial of service (device hang or reload) via crafted TCP packets, aka Bug ID CSCth41891, a different vulnerability than CVE-2011-0349. The problem is Bug ID CSCth41891 It is a problem. This vulnerability CVE-2011-0349 Is a different vulnerability.Skillfully crafted by a third party TCP Service disruption via packets (DoS) There is a possibility of being put into a state. Under certain configurations this vulnerability could allow: * Customers to access sites that would normally match a billing policy to be accessed without being charged to the end customer * Customers to access sites that would normally be denied based on configured restriction policies Additionally, Cisco IOS Software Release 12.4(24)MD1 on the Cisco CSG2 contains two vulnerabilities that can be exploited by a remote, unauthenticated attacker to create a denial of service condition that prevents traffic from passing through the CSG2. A three-way handshake is not required to exploit either of these vulnerabilities. Workarounds that mitigate these vulnerabilities are not available. This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20110126-csg2.shtml. Affected Products ================= The service policy bypass vulnerability affects all versions of the Cisco IOS Software for the CSG2 prior to the first fixed release, as indicated in the "Software Versions and Fixes" section of this advisory. No other Cisco IOS Software releases are affected. Vulnerable Products +------------------ To determine the version of Cisco IOS Software that is running on the Cisco CSG2, issue the "show module" command from Cisco IOS Software on the switch on which the Cisco CSG2 module is installed to identify what modules and sub-modules are installed on the system. Cisco CSG2 runs on the Cisco Service and Application Module for IP (SAMI) card, and is identified in the following example in slot 2 via the WS-SVC-SAMI-BB-K9 identification: C7600#show module Mod Ports Card Type Model Serial No. --- ----- -------------------------------------- ------------------ ----------- 1 2 Supervisor Engine 720 (Active) WS-SUP720-3BXL JAF1226ARQS 2 1 SAMI Module (csgk9) WS-SVC-SAMI-BB-K9 SAD113906P1 4 48 CEF720 48 port 10/100/1000mb Ethernet WS-X6748-GE-TX SAL1127T6XY Mod MAC addresses Hw Fw Sw Status --- ---------------------------------- ------ ------------ ------------ ------- 1 001e.be6e.a018 to 001e.be6e.a01b 5.6 8.5(2) 12.2(33)SRC5 Ok 2 001d.45f8.f3dc to 001d.45f8.f3e3 2.1 8.7(0.22)FW1 12.4(2010040 Ok 4 001c.587a.ef20 to 001c.587a.ef4f 2.6 12.2(14r)S5 12.2(33)SRC5 Ok Mod Sub-Module Model Serial Hw Status ---- --------------------------- ------------------ ----------- ------- ------- 1 Policy Feature Card 3 WS-F6K-PFC3BXL JAF1226BNQM 1.8 Ok 1 MSFC3 Daughterboard WS-SUP720 JAF1226BNMC 3.1 Ok 2 SAMI Daughterboard 1 SAMI-DC-BB SAD114400L9 1.1 Other 2 SAMI Daughterboard 2 SAMI-DC-BB SAD114207FU 1.1 Other 4 Centralized Forwarding Card WS-F6700-CFC SAL1029VGFK 2.0 Ok Mod Online Diag Status ---- ------------------- 1 Pass 2 Pass 4 Pass C7600# After locating the correct slot, issue the "session slot <module number> processor <3-9>" command to open a console connection to the respective Cisco CSG2. Once connected to the Cisco CSG2, perform the "show version" command: The following example shows that the Cisco CSG2 is running software Release 12.4(24)MD1: CSG2#show version Cisco IOS Software, SAMI Software (SAMI-CSGK9-M), Version 12.4(24)MD1, RELEASE SOFTWARE (fc2) Technical Support: http://www.cisco.com/techsupport Copyright (c) 1986-2010 by Cisco Systems, Inc. No other Cisco products are currently known to be affected by these vulnerabilities. Details ======= The Cisco Content Services Gateway - Second Generation (CSG2) provides intelligent network capabilities such as flexible policy management and billing based on deep-packet inspection, as well as subscriber and application awareness capabilities that enable mobile operators to quickly and easily offer value-added, differentiated services over their mobile data networks. The service policy bypass vulnerability affects configurations that allow end users to first access non-accounted or billed sites. After a user accesses a non-accounted site, it is possible to access other sites that are defined by a billing service policy or to access sites that may be blocked by other policies by sending specially crafted HTTP packets. This vulnerability only affects HTTP content traffic. HTTPS and other traffic types are not affected. A three-way handshake is not required to exploit either of these vulnerabilities. The vulnerabilities are triggered by TCP traffic that transits the Cisco CSG2. Vulnerability Scoring Details ============================= Cisco has provided scores for the vulnerabilities in this advisory based on the Common Vulnerability Scoring System (CVSS). The CVSS scoring in this Security Advisory is done in accordance with CVSS version 2.0. CVSS is a standards-based scoring method that conveys vulnerability severity and helps determine urgency and priority of response. Cisco has provided a base and temporal score. Customers can then compute environmental scores to assist in determining the impact of the vulnerability in individual networks. Cisco has provided an FAQ to answer additional questions regarding CVSS at: http://www.cisco.com/web/about/security/intelligence/cvss-qandas.html Cisco has also provided a CVSS calculator to help compute the environmental impact for individual networks at: http://intellishield.cisco.com/security/alertmanager/cvss * CSCtk35917 ("Service Policy Bypass Vulnerability") CVSS Base Score - 6.4 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - Partial Integrity Impact - Partial Availability Impact - None CVSS Temporal Score - 5.3 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed * CSCth41891/CSCth17178 ("Crafted TCP packet causes CSG2 to restart") CVSS Base Score - 7.8 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete CVSS Temporal Score - 6.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed Impact ====== Successful exploitation of the service policy bypass can allow customers to obtain access to sites that would normally be accounted and billed according to the billing policy without the billing policy being engaged. Additionally, customers could gain access to URLs that are configured in the Cisco CSG2 to be explicitly denied. Due to Cisco Bug ID CSCtg50821, the Cisco CSG2 may not automatically recover and may require a manual reload of the SAMI card by issuing the "hw-module module <x> reset" CLI command from the switch. Software Versions and Fixes =========================== When considering software upgrades, also consult http://www.cisco.com/go/psirt and any subsequent advisories to determine exposure and a complete upgrade solution. In all cases, customers should exercise caution to be certain the devices to be upgraded contain sufficient memory and that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, contact the Cisco Technical Assistance Center (TAC) or your contracted maintenance provider for assistance. Each row of the Cisco IOS Software table (below) names a Cisco IOS release train. If a release train is vulnerable, then the earliest possible releases that contain the fix (along with the anticipated date of availability for each, if applicable) are listed in the "First Fixed Release" column of the table. The "Recommended Release" column indicates the releases which have fixes for all the published vulnerabilities at the time of this Advisory. A device running a release in the given train that is earlier than the release in a specific column (less than the First Fixed Release) is known to be vulnerable. Cisco recommends upgrading to a release equal to or later than the release in the "Recommended Releases" column of the table. +---------------------------------------------------------------+ | Major | Availability of Repaired Releases | | Release | | |------------+--------------------------------------------------| | Affected | | | 12.x-Based | First Fixed Release | | Releases | | |------------+--------------------------------------------------| | 12.0 - | 12.0 through 12.3 based releases are not | | 12.3 | affected | |------------+--------------------------------------------------| | Affected | First Fixed Release | | 12.4-Based |--------------------------------------------------| | Releases | DoS | Service Policy Bypass | | | Vulnerabilities | Vulnerability | |------------+------------------+-------------------------------| | | All 12.4(11)MD | | | | releases are not | All 12.4(11)MD releases are | | | affected. | affected.

Cisco IOS 12.4(11)MD, 12.4(15)MD, 12.4(22)MD, 12.4(24)MD before 12.4(24)MD3, 12.4(22)MDA before 12.4(22)MDA5, and 12.4(24)MDA before 12.4(24)MDA3 on the Cisco Content Services Gateway Second Generation (aka CSG2) allows remote attackers to bypass intended access restrictions and intended billing restrictions by sending HTTP traffic to a restricted destination after sending HTTP traffic to an unrestricted destination, aka Bug ID CSCtk35917. The problem is Bug ID CSCtk35917 It is a problem.Third parties may circumvent restrictions such as access and billing. Cisco Content Services Gateway is prone to a security-bypass vulnerability. Exploiting this issue may allow attackers to access sites that are non-accounted or billed. This may lead to other attacks. This issue is being tracked by Cisco Bug ID CSCtk35917. Malicious attackers can exploit these vulnerabilities to bypass certain security restrictions, resulting in a denial of service. 1) There is a vulnerability when checking access policies. 2) There is an unknown vulnerability. 3) There is a second unidentified vulnerability. Under certain configurations this vulnerability could allow: * Customers to access sites that would normally match a billing policy to be accessed without being charged to the end customer * Customers to access sites that would normally be denied based on configured restriction policies Additionally, Cisco IOS Software Release 12.4(24)MD1 on the Cisco CSG2 contains two vulnerabilities that can be exploited by a remote, unauthenticated attacker to create a denial of service condition that prevents traffic from passing through the CSG2. These vulnerabilities require only a single content service to be active on the Cisco CSG2 and can be exploited via crafted TCP packets. A three-way handshake is not required to exploit either of these vulnerabilities. Workarounds that mitigate these vulnerabilities are not available. This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20110126-csg2.shtml. Affected Products ================= The service policy bypass vulnerability affects all versions of the Cisco IOS Software for the CSG2 prior to the first fixed release, as indicated in the "Software Versions and Fixes" section of this advisory. The two denial of service vulnerabilities only affect Cisco IOS Software Release 12.4(24)MD1 on the Cisco CSG2. No other Cisco IOS Software releases are affected. Vulnerable Products +------------------ To determine the version of Cisco IOS Software that is running on the Cisco CSG2, issue the "show module" command from Cisco IOS Software on the switch on which the Cisco CSG2 module is installed to identify what modules and sub-modules are installed on the system. Cisco CSG2 runs on the Cisco Service and Application Module for IP (SAMI) card, and is identified in the following example in slot 2 via the WS-SVC-SAMI-BB-K9 identification: C7600#show module Mod Ports Card Type Model Serial No. --- ----- -------------------------------------- ------------------ ----------- 1 2 Supervisor Engine 720 (Active) WS-SUP720-3BXL JAF1226ARQS 2 1 SAMI Module (csgk9) WS-SVC-SAMI-BB-K9 SAD113906P1 4 48 CEF720 48 port 10/100/1000mb Ethernet WS-X6748-GE-TX SAL1127T6XY Mod MAC addresses Hw Fw Sw Status --- ---------------------------------- ------ ------------ ------------ ------- 1 001e.be6e.a018 to 001e.be6e.a01b 5.6 8.5(2) 12.2(33)SRC5 Ok 2 001d.45f8.f3dc to 001d.45f8.f3e3 2.1 8.7(0.22)FW1 12.4(2010040 Ok 4 001c.587a.ef20 to 001c.587a.ef4f 2.6 12.2(14r)S5 12.2(33)SRC5 Ok Mod Sub-Module Model Serial Hw Status ---- --------------------------- ------------------ ----------- ------- ------- 1 Policy Feature Card 3 WS-F6K-PFC3BXL JAF1226BNQM 1.8 Ok 1 MSFC3 Daughterboard WS-SUP720 JAF1226BNMC 3.1 Ok 2 SAMI Daughterboard 1 SAMI-DC-BB SAD114400L9 1.1 Other 2 SAMI Daughterboard 2 SAMI-DC-BB SAD114207FU 1.1 Other 4 Centralized Forwarding Card WS-F6700-CFC SAL1029VGFK 2.0 Ok Mod Online Diag Status ---- ------------------- 1 Pass 2 Pass 4 Pass C7600# After locating the correct slot, issue the "session slot <module number> processor <3-9>" command to open a console connection to the respective Cisco CSG2.

Compiled Wed 07-Apr-10 09:50 by prod_rel_team --- output truncated --- Products Confirmed Not Vulnerable +-------------------------------- The Cisco Content Services Gateway - 1st Generation (CSG) is not affected by these vulnerabilities. No other Cisco products are currently known to be affected by these vulnerabilities. Details ======= The Cisco Content Services Gateway - Second Generation (CSG2) provides intelligent network capabilities such as flexible policy management and billing based on deep-packet inspection, as well as subscriber and application awareness capabilities that enable mobile operators to quickly and easily offer value-added, differentiated services over their mobile data networks. After a user accesses a non-accounted site, it is possible to access other sites that are defined by a billing service policy or to access sites that may be blocked by other policies by sending specially crafted HTTP packets. HTTPS and other traffic types are not affected. Both denial of service vulnerabilities require only a single content service to be active on the Cisco CSG2 and can be exploited via crafted TCP packets. A three-way handshake is not required to exploit either of these vulnerabilities. The vulnerabilities are triggered by TCP traffic that transits the Cisco CSG2. Vulnerability Scoring Details ============================= Cisco has provided scores for the vulnerabilities in this advisory based on the Common Vulnerability Scoring System (CVSS). The CVSS scoring in this Security Advisory is done in accordance with CVSS version 2.0. CVSS is a standards-based scoring method that conveys vulnerability severity and helps determine urgency and priority of response. Cisco has provided a base and temporal score. Customers can then compute environmental scores to assist in determining the impact of the vulnerability in individual networks. Cisco has provided an FAQ to answer additional questions regarding CVSS at: http://www.cisco.com/web/about/security/intelligence/cvss-qandas.html Cisco has also provided a CVSS calculator to help compute the environmental impact for individual networks at: http://intellishield.cisco.com/security/alertmanager/cvss * CSCtk35917 ("Service Policy Bypass Vulnerability") CVSS Base Score - 6.4 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - Partial Integrity Impact - Partial Availability Impact - None CVSS Temporal Score - 5.3 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed * CSCth41891/CSCth17178 ("Crafted TCP packet causes CSG2 to restart") CVSS Base Score - 7.8 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete CVSS Temporal Score - 6.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed Impact ====== Successful exploitation of the service policy bypass can allow customers to obtain access to sites that would normally be accounted and billed according to the billing policy without the billing policy being engaged. Additionally, customers could gain access to URLs that are configured in the Cisco CSG2 to be explicitly denied. Successful exploitation of either denial of service vulnerability could result in the Cisco CSG2 reloading or potentially hanging. Due to Cisco Bug ID CSCtg50821, the Cisco CSG2 may not automatically recover and may require a manual reload of the SAMI card by issuing the "hw-module module <x> reset" CLI command from the switch. Software Versions and Fixes =========================== When considering software upgrades, also consult http://www.cisco.com/go/psirt and any subsequent advisories to determine exposure and a complete upgrade solution. In all cases, customers should exercise caution to be certain the devices to be upgraded contain sufficient memory and that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, contact the Cisco Technical Assistance Center (TAC) or your contracted maintenance provider for assistance. Each row of the Cisco IOS Software table (below) names a Cisco IOS release train. If a release train is vulnerable, then the earliest possible releases that contain the fix (along with the anticipated date of availability for each, if applicable) are listed in the "First Fixed Release" column of the table. The "Recommended Release" column indicates the releases which have fixes for all the published vulnerabilities at the time of this Advisory. A device running a release in the given train that is earlier than the release in a specific column (less than the First Fixed Release) is known to be vulnerable. Cisco recommends upgrading to a release equal to or later than the release in the "Recommended Releases" column of the table. +---------------------------------------------------------------+ | Major | Availability of Repaired Releases | | Release | | |------------+--------------------------------------------------| | Affected | | | 12.x-Based | First Fixed Release | | Releases | | |------------+--------------------------------------------------| | 12.0 - | 12.0 through 12.3 based releases are not | | 12.3 | affected | |------------+--------------------------------------------------| | Affected | First Fixed Release | | 12.4-Based |--------------------------------------------------| | Releases | DoS | Service Policy Bypass | | | Vulnerabilities | Vulnerability | |------------+------------------+-------------------------------| | | All 12.4(11)MD | | | | releases are not | All 12.4(11)MD releases are | | | affected. | affected.
