VAR-200903-0109 CVE-2008-6474 F5 BIG-IP Any in the management interface of Perl Code injection vulnerability CVSS V2: 9.0
CVSS V3: -
Severity: HIGH
The management interface in F5 BIG-IP 9.4.3 allows remote authenticated users with Resource Manager privileges to inject arbitrary Perl code via unspecified configuration settings related to Perl EP3 with templates, probably triggering static code injection. F5 BIG-IP Web Management Interface is prone to a remote code-injection vulnerability because the application fails to properly sanitize user-supplied input. Exploiting this issue allows attackers to execute arbitrary code with the privileges of the user running the affected application. This issue affects F5 BIG-IP 9.4.3; other versions may also be affected. F5 BIG-IP is an all-in-one network device integrated with network traffic management, application security management, load balancing and other functions from F5 Corporation of the United States. The vulnerability is caused by using Perl EP3 with templates similar to the following without escaping the single quotes in NEW_VALUE: $val=&\'\'NEW_VALUE&\'\'; ​​For example, the SNMP community string configuration accepts The following value is an SNMP request: \"none\'\'.`touch /etc/foo`.\'\'\" An attacker can create a specially crafted URL link that can inject an HTTP GET request through cross-site scripting in BIG-IP Make any changes on the device

CVSS V3: -
Severity: MEDIUM
Heap-based buffer overflow in quickTime.qts in Apple QuickTime before 7.4.5 allows remote attackers to execute arbitrary code via a crafted PICT image file, related to an improperly terminated memory copy loop. User interaction is required to exploit this vulnerability in that the target must open a malicious file.The specific flaw exists in the quickTime.qts while parsing corrupted .pict files. The module contains a vulnerable memory copy loop which searches for a terminator value. When this value is changed or omitted, a heap corruption occurs allowing the execution of arbitrary code. These issues arise when the application handles specially crafted Java applets, image files, and movie files. Successful exploits may allow attackers to obtain sensitive information, gain remote unauthorized access in the context of a vulnerable user, and trigger a denial-of-service condition. Versions prior to QuickTime 7.4.5 are affected by these vulnerabilities.

VAR-200804-0029 CVE-2008-1016 Apple QuickTime Memory corruption vulnerability due to incomplete movie media track processing CVSS V2: 6.8
CVSS V3: -
Severity: MEDIUM
Apple QuickTime before 7.4.5 does not properly handle movie media tracks, which allows remote attackers to execute arbitrary code via a crafted movie that triggers memory corruption. These issues arise when the application handles specially crafted Java applets, image files, and movie files. Successful exploits may allow attackers to obtain sensitive information, gain remote unauthorized access in the context of a vulnerable user, and trigger a denial-of-service condition. Versions prior to QuickTime 7.4.5 are affected by these vulnerabilities. Apple QuickTime is a very popular multimedia player. ---------------------------------------------------------------------- A new version (0.9.0.0 - Release Candidate 1) of the free Secunia PSI has been released. The new version includes many new and advanced features, which makes it even easier to stay patched. 1) An implementation error in QuickTime for Java allows untrusted Java applets to deserialize objects provided by QTJava. This can be exploited to disclose sensitive information or execute arbitrary code e.g. when a user visits a malicious web page. 2) An unspecified error in the handling of external URLs embedded in movie files can lead to information disclosure. 3) An input validation error in the handling of data reference atoms within movie files can be exploited to cause a buffer overflow when a specially crafted movie is viewed. 5) A boundary error in the parsing of "crgn" atoms can be exploited to cause a heap-based buffer overflow when a specially crafted movie file is viewed. 6) A boundary error in the parsing of "chan" atoms can be exploited to cause a heap-based buffer overflow when a specially crafted movie file is viewed. 7) A boundary error in the handling of PICT records can be exploited to cause a heap-based buffer overflow when a specially crafted PICT image is viewed. 8) A boundary error in the handling of error messages when processing PICT images can be exploited to cause a heap-based buffer overflow. NOTE: This vulnerability does not affect Mac OS X systems. 9) A boundary error in the handling of Animation codec content can be exploited to cause a heap-based buffer overflow when a specially crafted movie file is viewed. NOTE: This vulnerability does not affect Mac OS X systems. 10) A boundary error in the parsing of "obji" atoms can be exploited to cause a stack-based buffer overflow when a specially crafted QuickTime VR movie file is viewed. 11) A boundary error in the parsing of the Clip opcode can be exploited to cause a heap-based buffer overflow when a specially crafted PICT image file is viewed.

CVSS V3: -
Severity: MEDIUM
Heap-based buffer overflow in quickTime.qts in Apple QuickTime before 7.4.5 on Windows allows remote attackers to execute arbitrary code via a crafted PICT image file with Kodak encoding, related to error checking and error messages. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within the quicktime.qts library responsible for parsing Kodak encoded images. A lack of proper error checking can result in a heap based buffer overflow leading to arbitrary code execution under the context of the currently logged in user. These issues arise when the application handles specially crafted Java applets, image files, and movie files. Successful exploits may allow attackers to obtain sensitive information, gain remote unauthorized access in the context of a vulnerable user, and trigger a denial-of-service condition. Versions prior to QuickTime 7.4.5 are affected by these vulnerabilities. Apple QuickTime is a very popular multimedia player. ---------------------------------------------------------------------- A new version (0.9.0.0 - Release Candidate 1) of the free Secunia PSI has been released. The new version includes many new and advanced features, which makes it even easier to stay patched. 1) An implementation error in QuickTime for Java allows untrusted Java applets to deserialize objects provided by QTJava. This can be exploited to disclose sensitive information or execute arbitrary code e.g. when a user visits a malicious web page. 2) An unspecified error in the handling of external URLs embedded in movie files can lead to information disclosure. 3) An input validation error in the handling of data reference atoms within movie files can be exploited to cause a buffer overflow when a specially crafted movie is viewed. 4) An unspecified error in the handling of movie media tracks can be exploited to cause a memory corruption when a specially crafted movie is viewed. 6) A boundary error in the parsing of "chan" atoms can be exploited to cause a heap-based buffer overflow when a specially crafted movie file is viewed. NOTE: This vulnerability does not affect Mac OS X systems. NOTE: This vulnerability does not affect Mac OS X systems. 10) A boundary error in the parsing of "obji" atoms can be exploited to cause a stack-based buffer overflow when a specially crafted QuickTime VR movie file is viewed.

Successful exploits may allow attackers to obtain sensitive information, gain remote unauthorized access in the context of a vulnerable user, and trigger a denial-of-service condition. Versions prior to QuickTime 7.4.5 are affected by these vulnerabilities. Apple QuickTime is a very popular multimedia player. There is a heap overflow vulnerability when QuickTime parses the chan atom. ---------------------------------------------------------------------- A new version (0.9.0.0 - Release Candidate 1) of the free Secunia PSI has been released. The new version includes many new and advanced features, which makes it even easier to stay patched. 1) An implementation error in QuickTime for Java allows untrusted Java applets to deserialize objects provided by QTJava. This can be exploited to disclose sensitive information or execute arbitrary code e.g. when a user visits a malicious web page. 2) An unspecified error in the handling of external URLs embedded in movie files can lead to information disclosure. 3) An input validation error in the handling of data reference atoms within movie files can be exploited to cause a buffer overflow when a specially crafted movie is viewed. 4) An unspecified error in the handling of movie media tracks can be exploited to cause a memory corruption when a specially crafted movie is viewed. 5) A boundary error in the parsing of "crgn" atoms can be exploited to cause a heap-based buffer overflow when a specially crafted movie file is viewed. 7) A boundary error in the handling of PICT records can be exploited to cause a heap-based buffer overflow when a specially crafted PICT image is viewed. 8) A boundary error in the handling of error messages when processing PICT images can be exploited to cause a heap-based buffer overflow. NOTE: This vulnerability does not affect Mac OS X systems. 9) A boundary error in the handling of Animation codec content can be exploited to cause a heap-based buffer overflow when a specially crafted movie file is viewed. NOTE: This vulnerability does not affect Mac OS X systems. 10) A boundary error in the parsing of "obji" atoms can be exploited to cause a stack-based buffer overflow when a specially crafted QuickTime VR movie file is viewed. 11) A boundary error in the parsing of the Clip opcode can be exploited to cause a heap-based buffer overflow when a specially crafted PICT image file is viewed.

CVSS V3: -
Severity: HIGH
Stack-based buffer overflow in the AutoFix Support Tool ActiveX control 2.7.0.1 in SYMADATA.DLL in multiple Symantec Norton products, including Norton 360 1.0, AntiVirus 2006 through 2008, Internet Security 2006 through 2008, and System Works 2006 through 2008, allows remote attackers to execute arbitrary code via a long argument to the GetEventLogInfo method. NOTE: some of these details are obtained from third party information. Symantec AutoFix Support Tool ActiveX control is prone to a buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied input. An attacker can exploit this issue to execute arbitrary code in the context of an application using the ActiveX control (typically Internet Explorer). Failed attacks will likely cause denial-of-service conditions. NOTE: To exploit this issue, an attacker must entice an unsuspecting victim to to visit a malicious website masquerading as a trusted Symantec site. ---------------------------------------------------------------------- A new version (0.9.0.0 - Release Candidate 1) of the free Secunia PSI has been released. The new version includes many new and advanced features, which makes it even easier to stay patched. 2) A design error in the same ActiveX control can be exploited to e.g. load and execute arbitrary code from a remote share. conducts DNS poisoning or cross-site scripting attacks as the ActiveX control is site-locked and can only be scripted from a trusted domain. https://www-secure.symantec.com/techsupp/asa/install.jsp PROVIDED AND/OR DISCOVERED BY: The vendor credits Peter Vreugdenhill and an anonymous person, both reported via iDefense Labs.

BACKGROUND Norton Internet Security 2008 is a system security suite that offers protection from spyware, viruses, identity theft, spam, and malicious network traffic. More information can be found on the vendor's site at the following URL. http://www.symantec.com/home_homeoffice/products/overview.jsp?pcid=is&pvid=nis2008 II. III. In order for exploitation to occur, an attacker would have to lure a vulnerable user to a malicious web site. While this control is marked as safe for scripting, the control has been designed so that it can only be run from the "symantec.com" domain. In practice this requirement can be bypassed through the use of any Cross Site Scripting (XSS) vulnerabilities in the Symantec domain. Exploitation could also occur through the use of DNS poisoning attacks. IV. DETECTION iDefense confirmed that this vulnerability exists in version 2.7.0.1 of the control that is installed with the 2008 version of Norton Internet Security. Other versions may also be available. V. WORKAROUND Setting the kill-bit for this control will prevent it from being loaded within Internet Explorer. However, doing so will prevent legitimate use of the control. VI. VENDOR RESPONSE Symantec has addressed this vulnerability by releasing updates. For more information, refer to their advisory at the following URL. http://www.symantec.com/avcenter/security/Content/2008.04.02a.html VII. CVE INFORMATION The Common Vulnerabilities and Exposures (CVE) project has assigned the name CVE-2008-0312 to this issue. This is a candidate for inclusion in the CVE list (http://cve.mitre.org/), which standardizes names for security problems. VIII.

CVSS V3: -
Severity: MEDIUM
The ActiveDataInfo.LaunchProcess method in the SymAData.ActiveDataInfo.1 ActiveX control 2.7.0.1 in SYMADATA.DLL in multiple Symantec Norton products including Norton 360 1.0, AntiVirus 2006 through 2008, Internet Security 2006 through 2008, and System Works 2006 through 2008, does not properly determine the location of the AutoFix Tool, which allows remote attackers to execute arbitrary code via a remote (1) WebDAV or (2) SMB share. An ActiveX control in the Symantec AutoFix Tool is prone to a vulnerability due to an insecure method. Attackers can leverage this issue to load an arbitrary file onto a victim's computer and then execute it with the privileges of the application running the control (typically Internet Explorer). This issue is exploitable only when a victim's computer is configured to allow remote connections to WebDav or SMB shares. Successful exploits will compromise affected computers. iDefense Security Advisory 04.02.08 http://labs.idefense.com/intelligence/vulnerabilities/ Apr 02, 2008 I.

VAR-200803-0326 CVE-2008-1150 Cisco IOS denial-of-service vulnerability

Related entries in the VARIoT exploits database: VAR-E-200803-0750
CVSS V2: 7.1
CVSS V3: -
Severity: HIGH
The virtual private dial-up network (VPDN) component in Cisco IOS before 12.3 allows remote attackers to cause a denial of service (resource exhaustion) via a series of PPTP sessions, related to the persistence of interface descriptor block (IDB) data structures after process termination, aka bug ID CSCdv59309. A vulnerability in the way Cisco IOS handles IPv6 packets could result in a remotely exploitable denial of service. Cisco IOS is prone to multiple denial-of-service vulnerabilities that occur in the virtual private dial-up (VPDN) when the Point-to-Point Tunneling Protocol (PPTP) is enabled. Successfully exploiting these issues may cause a memory leak or prevent the establishment of VPDN connections, denying service to legitimate users. ---------------------------------------------------------------------- A new version (0.9.0.0 - Release Candidate 1) of the free Secunia PSI has been released. The new version includes many new and advanced features, which makes it even easier to stay patched. 3) Some errors exist in the Data-Link-Switching (DLSw) feature when processing UDP and IP protocol 91 packets. 4) An error exists in the processing of IPv6 packets, which can be exploited to prevent the interface from receiving additional traffic or to cause the device to crash (if RSVP service is configured on the interface) by sending a specially crafted IPv6 packet to the device. Successful exploitation of this vulnerability requires that IPv6 and certain IPv4 UDP services are enabled. 5) An error exists in the implementation of Multicast Virtual Private Networks (MVPN), which can be exploited to create extra multicast states on the core routers via specially crafted Multicast Distribution Tree (MDT) Data Join messages. This can also be exploited to receive multicast traffic from VPNs that are not connected to the same Provider Edge (PE). Successful exploitation of the multicast traffic leak requires that the attacker knows or guesses the Border Gateway Protocol (BGP) peering IP address of a remote PE router and the address of the multicast group that is used in other MPLS VPNs. SOLUTION: Update to the fixed version (please see the vendor's advisories for details). 5) The vendor credits Thomas Morin.

PPTP is only one of the supported tunneling protocols used to tunnel PPP frames within the VPDN solution. The first vulnerability is a memory leak that occurs as a result of PPTP session termination. The second vulnerability may consume all interface descriptor blocks on the affected device because those devices will not reuse virtual access interfaces. If these vulnerabilities are repeatedly exploited, the memory and/or interface resources of the attacked device may be depleted. Cisco has made free software available to address these vulnerabilities for affected customers. There are no workarounds available to mitigate the effects of these vulnerabilities. This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20080326-pptp.shtml Note: The March 26, 2008 publication includes five security advisories. The advisories all address vulnerabilities in Cisco's Internetwork Operating System (IOS) software. Each advisory lists the releases that correct the vulnerability described in the advisory, and also lists the releases that correct the vulnerabilities in the other five advisories. Please reference the following software table to find a release that fixes all published software advisories as of March 26th, 2008: * March 26th Bundled IOS Advisory Table http://www.cisco.com/warp/public/707/cisco-sa-20080326-bundle.shtml Individual publication links are listed below: * Cisco IOS Virtual Private Dial-up Network Denial of Service Vulnerability http://www.cisco.com/warp/public/707/cisco-sa-20080326-pptp.shtml * Multiple DLSw Denial of Service Vulnerabilities in Cisco IOS http://www.cisco.com/warp/public/707/cisco-sa-20080326-dlsw.shtml * Cisco IOS User Datagram Protocol Delivery Issue For IPv4/IPv6 Dual-stack Routers http://www.cisco.com/warp/public/707/cisco-sa-20080326-IPv4IPv6.shtml * Vulnerability in Cisco IOS with OSPF, MPLS VPN, and Supervisor 32, Supervisor 720, or Route Switch Processor 720 http://www.cisco.com/warp/public/707/cisco-sa-20080326-queue.shtml * Cisco IOS Multicast Virtual Private Network (MVPN) Data Leak http://www.cisco.com/warp/public/707/cisco-sa-20080326-mvpn.shtml Affected Products ================= Devices that are running certain Cisco IOS versions prior to 12.3 with VPDN enabled may be affected by these vulnerabilities. Vulnerable Products +------------------ Devices that are running affected versions of Cisco IOS with VPDN enabled and are configured to accept termination of PPTP sessions are vulnerable. To determine whether VPDN is enabled on your device, log in to the device and issue the command-line interface (CLI) command "show running-config". If the output contains "vpdn enable" along with a "vpdn-group <name>" command, VPDN is enabled on the device. The device will accept termination of PPTP sessions if the command "protocol any" or "protocol pptp" is defined under the "vpdn-group <name>" command. The following example shows a device that is running VPDN and will accept termination of PPTP sessions: Router#show running-config Building configuration... ! !--- Output truncated. ! vpdn enable ! vpdn-group test_only ! Default PPTP VPDN group accept-dialin protocol pptp virtual-template 1 ! !---Remaining output truncated. To determine the software version running on a Cisco product, log in to the device and issue the "show version" command to display the system banner. Cisco IOS software will identify itself as "Internetwork Operating System Software" or simply "IOS." On the next line of output, the image name will be displayed between parentheses, followed by "Version" and the IOS release name. Other Cisco devices will not have the "show version" command or will give different output. The following example identifies a Cisco product that is running Cisco IOS release 12.2(7): Cisco Internetwork Operating System Software IOS (tm) 7200 Software (C7200-IS-M), Version 12.2(7), RELEASE SOFTWARE (fc1) Copyright (c) 1986-2002 by cisco Systems, Inc. Compiled Tue 15-Jan-02 18:31 by pwade Image text-base: 0x600089C0, data-base: 0x613A6000 Additional information about Cisco IOS release naming can be found at http://www.cisco.com/warp/public/620/1.html. Products Confirmed Not Vulnerable +-------------------------------- Devices that are running Cisco IOS versions 12.3 and later are not affected by these vulnerabilities. Devices that are explicitly configured for VPDN protocols other than PPTP are not affected. Devices that are running Cisco IOS versions prior to 12.3 and do not have VPDN enabled are not affected by these vulnerabilities. Cisco IOS XR is not affected by these vulnerabilities. Details ======= VPDNs securely carry private data over a public network, allowing remote users to access a private network over a shared infrastructure such as the Internet. VPDNs maintain the same security and management policies as a private network, while providing a cost-effective method for point-to-point connections between remote users and a central network. PPTP is a network protocol that enables the secure transfer of data from a remote client to a private enterprise server by creating a VPDN across TCP/IP-based data networks. PPTP supports on-demand, multiprotocol, virtual private networking over public networks, such as the Internet. Details regarding the two known vulnerabilities in Cisco IOS devices that are running affected versions of system software follow: * Memory Leak due to PPTP Session Termination Upon completion of a PPTP session, memory is leaked from the processor memory on the terminating device. This is shown in the output of "show process memory" under the *Dead* process. The *Dead* process is not a real process. Its function is to account for the memory that is allocated under the context of another process which has terminated, in this case PPTP. When the administrator is logged into the device, if the device is under exploitation, the Holding entry of the *Dead* process under the "show process memory" command will be increasing. Following is an example showing a device that is holding *Dead* memory: Router#show process memory Total: 199718560, Used: 11147828, Free: 188570732 PID TTY Allocated Freed Holding Getbufs Retbufs Process 0 0 99812 1848 8415816 0 0 *Init* 0 0 444 778840 444 0 0 *Sched* 0 0 17481700 4930848 819672 180908 0 *Dead* 1 0 284 284 3828 0 0 Load Meter !--- Output truncated. The CLI command "show memory dead" allows administrators to examine the contents of *Dead*. The output will display many occurrences of PPTP in the output if the PPTP process is causing the leak. The following example shows the dead memory for a device that has been exploited by the vulnerability Router#show memory dead Head Total(b) Used(b) Free(b) Lowest(b) Largest(b) Processor 6225FF40 224002240 11906736 212095504 212082872 212084464 I/O 20000000 33554440 994136 32560304 32560304 32560252 I/O-2 F800000 8388616 1020632 7367984 7367984 7367932 Processor memory Address Bytes Prev Next Ref PrevF NextF Alloc PC what 62275DC8 0000000048 62275D68 62275E24 001 ------- ------- 60654230 PPTP create idb 62275E24 0000000052 62275DC8 62275E84 001 ------- ------- 60654230 PPTP create idb 62275E84 0000000052 62275E24 62275EE4 001 ------- ------- 60654230 PPTP create idb .... !--- remaining output truncated. This vulnerability is documented in Cisco bug ID CSCsj58566 and Common Vulnerabilities and Exposures (CVE) identifier CVE-2008-1151 has been assigned to this vulnerability. * Virtual Access Interfaces Are Not Re-used Upon completion of a PPTP session, affected devices do not remove the virtual access interface that is associated with the PPTP session and do not reuse the interfaces in any future connections. This situation can result in an exhaustion of the interface descriptor block (IDB) limit, which will prevent any new interfaces being created within Cisco IOS, effectively blocking all new VPDN connections, even though the router may still have enough processor memory to remain up and running. A reload of the device is required to remove the interfaces. An IDB is a Cisco IOS internal data structure that contains information such as the IP address, interface state, and packet statistics. Cisco IOS software maintains one IDB for each interface present on a platform and one IDB for each subinterface. Further documentation on Cisco IOS IDBs can be found at: http://www.cisco.com/en/US/products/sw/iosswrel/ps1835/products_tech_note09186a0080094322.shtml This vulnerability is documented in Cisco bug ID CSCdv59309 and Common Vulnerabilities and Exposures (CVE) identifier CVE-2008-1150 has been assigned to this vulnerability. Vulnerability Scoring Details ============================= Cisco is providing 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. Cisco will provide a base and temporal score. Customers can then compute environmental scores to assist in determining the impact of the vulnerability in individual networks. CVSS is a standards based scoring method that conveys vulnerability severity and helps determine urgency and priority of response. 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 CSCsj58566 - Memory Leak due to PPTP Session Termination CVSS Base Score - 7.1 Access Vector: Network Access Complexity: Medium Authentication: None Confidentiality Impact: None Integrity Impact: None Availability Impact: Complete CVSS Temporal Score - 5.9 Exploitability: Functional Remediation Level: Official-Fix Report Confidence: Confirmed CSCdv59309 - Virtual Access Interfaces Are Not Re-used CVSS Base Score - 4.3 Access Vector: Network Access Complexity: Medium Authentication: None Confidentiality Impact: None Integrity Impact: None Availability Impact: Partial CVSS Temporal Score - 3.6 Exploitability: Functional Remediation Level: Official-Fix Report Confidence: Confirmed Impact ====== Successful exploitation of the vulnerability may result in a memory leak of processor memory or consumption of all available IDBs on the device. With continued exploitation, the device will deplete its processor memory or reach an IDB limit. Both impacts would result in a denial of service condition for the device. 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 given 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 | | Release | Releases | |------------+---------------------------| | Affected | First Fixed | Recommended | | 12.0-Based | Release | Release | | Releases | | | |------------+-------------+-------------| | 12.0 | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0DA | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0DB | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0DC | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0S | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0SC | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0SL | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0SP | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0ST | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0SX | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0SY | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0SZ | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0T | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0W | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0WC | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0WT | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0XA | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0XB | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0XC | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0XD | Not | | | | Vulnerable | | |------------+-------------+-------------| | | Releases | | | | prior to | | | | 12.0(7)XE2 | | | | are | | | 12.0XE | vulnerable, | | | | release | | | | 12.0(7)XE2 | | | | and later | | | | are not | | | | vulnerable;

Cisco recommends upgrading to the fixed version of Cisco IOS. Obtaining Fixed Software ======================== Cisco will make free software available to address this vulnerability for affected customers. This advisory will be updated as fixed software becomes available. Prior to deploying software, customers should consult their maintenance provider or check the software for feature set compatibility and known issues specific to their environment. Customers may only install and expect support for the feature sets they have purchased. By installing, downloading, accessing or otherwise using such software upgrades, customers agree to be bound by the terms of Cisco's software license terms found at http://www.cisco.com/public/sw-license-agreement.html or as otherwise set forth at Cisco.com Downloads at http://www.cisco.com/public/sw-center/sw-usingswc.shtml. Do not contact either "psirt@cisco.com" or "security-alert@cisco.com" for software upgrades. Customers with Service Contracts +------------------------------- Customers with contracts should obtain upgraded software through their regular update channels. For most customers, this means that upgrades should be obtained through the Software Center on Cisco's worldwide website at http://www.cisco.com. Customers using Third Party Support Organizations +------------------------------------------------ Customers whose Cisco products are provided or maintained through prior or existing agreement with third-party support organizations such as Cisco Partners, authorized resellers, or service providers should contact that support organization for guidance and assistance with the appropriate course of action in regards to this advisory. The effectiveness of any workaround or fix is dependent on specific customer situations such as product mix, network topology, traffic behavior, and organizational mission. Due to the variety of affected products and releases, customers should consult with their service provider or support organization to ensure any applied workaround or fix is the most appropriate for use in the intended network before it is deployed. Customers without Service Contracts +---------------------------------- Customers who purchase direct from Cisco but who do not hold a Cisco service contract and customers who purchase through third-party vendors but are unsuccessful at obtaining fixed software through their point of sale should get their upgrades by contacting the Cisco Technical Assistance Center (TAC). TAC contacts are as follows. * +1 800 553 2447 (toll free from within North America) * +1 408 526 7209 (toll call from anywhere in the world) * e-mail: tac@cisco.com Have your product serial number available and give the URL of this notice as evidence of your entitlement to a free upgrade.

Severity: HIGH
The data-link switching (DLSw) component in Cisco IOS 12.0 through 12.4 allows remote attackers to cause a denial of service (device restart or memory consumption) via crafted (1) UDP port 2067 or (2) IP protocol 91 packets. A vulnerability in the way Cisco IOS handles IPv6 packets could result in a remotely exploitable denial of service. Cisco IOS is prone to multiple remote denial-of-service vulnerabilities because the software fails to properly handle malformed network datagrams. Successfully exploiting these issues allows remote attackers to trigger memory leaks or crashes in targeted devices. This will lead to denial-of-service conditions. These issues are tracked by Cisco Bug ID CSCsk73104. ---------------------------------------------------------------------- A new version (0.9.0.0 - Release Candidate 1) of the free Secunia PSI has been released. The new version includes many new and advanced features, which makes it even easier to stay patched. 1) A memory leak exists in the handling of completed PPTP sessions, which can be exploited to exhaust memory on an affected system. 2) An error exists in the handling of PPTP sessions when virtual access interfaces are not removed from the interface descriptor block (IDB) and are not reused. This can result in an exhaustion of the interface descriptor block (IDB) limit. This can be exploited to cause a reload of the system or a memory leak. Successful exploitation of this vulnerability requires that IPv6 and certain IPv4 UDP services are enabled. 5) An error exists in the implementation of Multicast Virtual Private Networks (MVPN), which can be exploited to create extra multicast states on the core routers via specially crafted Multicast Distribution Tree (MDT) Data Join messages. This can also be exploited to receive multicast traffic from VPNs that are not connected to the same Provider Edge (PE). Successful exploitation of the multicast traffic leak requires that the attacker knows or guesses the Border Gateway Protocol (BGP) peering IP address of a remote PE router and the address of the multicast group that is used in other MPLS VPNs. SOLUTION: Update to the fixed version (please see the vendor's advisories for details).

Please reference the following software table to find a release which fixes all published Security Advisories as of March 26th, 2008. * March 26th bundled IOS Advisory Table http://www.cisco.com/warp/public/707/cisco-sa-20080326-bundle.shtml Individual publication links are listed below: * Cisco IOS Virtual Private Dial-up Network Denial of Service Vulnerability http://www.cisco.com/warp/public/707/cisco-sa-20080326-pptp.shtml * Multiple DLSw Denial of Service Vulnerabilities in Cisco IOS http://www.cisco.com/warp/public/707/cisco-sa-20080326-dlsw.shtml * Cisco IOS User Datagram Protocol Delivery Issue For IPv4/IPv6 Dual-stack Routers http://www.cisco.com/warp/public/707/cisco-sa-20080326-IPv4IPv6.shtml * Vulnerability in Cisco IOS with OSPF, MPLS VPN, and Supervisor 32, Supervisor 720, or Route Switch Processor 720 http://www.cisco.com/warp/public/707/cisco-sa-20080326-queue.shtml * Cisco IOS Multicast Virtual Private Network (MVPN) Data Leak http://www.cisco.com/warp/public/707/cisco-sa-20080326-mvpn.shtml Affected Products ================= Vulnerable Products +------------------ This security advisory applies to all Cisco products that run any version of affected Cisco IOS software configured for DLSw. Systems that contain the DLSw feature, but do not have it enabled, are not affected. Routers enabled for DLSw contain a line in the configuration defining a local DLSw peer. This configuration can be observed by issuing the command "show running-config". Systems configured for DLSw contain lines similar to the following: "dlsw local-peer" or "dlsw local-peer peer-id <IP address>" Any version of Cisco IOS prior to the versions which are listed in the Software Versions and Fixes section below is vulnerable. To determine the version of Cisco IOS software running on a Cisco product, log in to the device and issue the show version command to display the system banner. Cisco IOS Software will identify itself as "Internetwork Operating System Software" or simply "IOS". On the next line of output, the image name will be displayed between parentheses, followed by "Version" and the IOS release name. Other Cisco devices will not have the "show version" command or will give different output. The following example identifies a Cisco product running Cisco IOS Software Release 12.3(6) with an installed image name of C3640-IS-M: Cisco Internetwork Operating System Software IOS (tm) 3600 Software (C3640-IS-M), Version 12.3(6), RELEASE SOFTWARE (fc3) The next example shows a product running Cisco IOS Software Release 12.3(11)T3 with an image name of C3845-ADVIPSERVICESK9-M: Cisco IOS Software, 3800 Software (C3845-ADVIPSERVICESK9-M), Version 12.3(11)T3, RELEASE SOFTWARE (fc4) Technical Support: http://www.cisco.com/techsupport Copyright (c) 1986-2005 by Cisco Systems, Inc. Additional information about Cisco IOS release naming can be found at http://www.cisco.com/warp/public/620/1.html. Products Confirmed Not Vulnerable +-------------------------------- Cisco IOS devices that are not configured for DLSw are not vulnerable. No other Cisco products are currently known to be affected by these vulnerabilities. Details ======= Data-link switching (DLSw) provides a means of transporting IBM Systems Network Architecture (SNA) and network basic input/output system (NetBIOS) traffic over an IP network. Cisco implementation of DLSw also uses UDP port 2067 and IP Protocol 91 for Fast Sequenced Transport (FST). These vulnerabilities do not affect TCP packet processing. A successful exploitation may result in a reload of the system or a memory leak on the device, leading to a denial of service (DoS) condition. Cisco IOS devices configured for DLSw with "dlsw local-peer" automatically listen for IP protocol 91 packets. Cisco IOS devices listen to IP protocol 91 packets when DLSw is configured. However, it is only used if DLSw is configured for Fast Sequenced Transport (FST). A DLSw FST peer configuration will contain the following line: "dlsw remote-peer 0 fst <ip-address>" It is possible to disable UDP processing in DLSw with the "dlsw udp-disable" command. However, disabling UDP only prevents the sending of UDP packets, it does not prevent the device from receiving and processing incoming UDP packets. 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 CSCsk73104 - Handling of malformed packets by DLSW 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 these vulnerabilities may result in the reload of the device or memory leaks, leading to a DoS condition. 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 given 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 | | Release | Releases | |------------+---------------------------| | Affected | First Fixed | Recommended | | 12.0-Based | Release | Release | | Releases | | | |------------+-------------+-------------| | | Vulnerable;

Workarounds =========== The workaround consists of filtering UDP packets to port 2067 and IP protocol 91 packets. Filters can be applied at network boundaries to filter all IP protocol 91 packets and UDP packets to port 2067 or can be applied on individual affected devices to permit such traffic only from trusted peer IP addresses. However, since both of the protocols are connectionless, it is possible for an attacker to spoof malformed packets from legitimate peer IP addresses. As soon as DLSw is configured, the Cisco IOS device begins listening on IP protocol 91. However, this protocol is only used if DLSw is configured for Fast Sequenced Transport (FST). A DLSw FST peer configuration will contain the following line: "dlsw remote-peer 0 fst <ip-address>" If FST is used, filtering IP protocol 91 will break the operation, so filters need to permit protocol 91 traffic from legitimate peer IP addresses. It is possible to disable UDP processing in DLSw with the "dlsw udp-disable" command. However, disabling UDP only prevents the sending of UDP packets, it does not prevent the receiving and processing of incoming UDP packets. To protect a vulnerable device from malicious packets via UDP port 2067, both of the following actions must be taken: 1. Disable UDP outgoing packets with the "dlsw udp-disable" command, AND 2. Filter UDP 2067 in the vulnerable device using infrastructure ACL. Additional mitigation techniques that can be deployed on Cisco devices within the network are available in the Cisco Applied Mitigation Bulletin companion document for this advisory: http://www.cisco.com/warp/public/707/cisco-amb-20080326-dlsw.shtml Using Control Plane Policing on Affected Devices +----------------------------------------------- Control Plane Policing (CoPP) can be used to block untrusted DLSw traffic to the device. Cisco IOS software releases 12.0S, 12.2SX, 12.2S, 12.3T, 12.4, and 12.4T support the CoPP feature. CoPP may be configured on a device to protect the management and control planes to minimize the risk and effectiveness of direct infrastructure attacks by explicitly permitting only authorized traffic sent to infrastructure devices in accordance with existing security policies and configurations. The following example, which uses 192.168.100.1 to represent a trusted host, can be adapted to your network. If FST is not used, protocol 91 may be completely filtered. Additionally, if UDP is disabled with the "dlsw udp-disable" command, UDP port 2067 may also be completely filtered. !--- Deny DLSw traffic from trusted hosts to all IP addresses !--- configured on all interfaces of the affected device so that !--- it will be allowed by the CoPP feature access-list 111 deny udp host 192.168.100.1 any eq 2067 access-list 111 deny 91 host 192.168.100.1 any !--- Permit all other DLSw traffic sent to all IP addresses !--- configured on all interfaces of the affected device so that it !--- will be policed and dropped by the CoPP feature access-list 111 permit udp any any eq 2067 access-list 111 permit 91 any any !--- Permit (Police or Drop)/Deny (Allow) all other Layer 3 and Layer 4 !--- traffic in accordance with existing security policies and !--- configurations for traffic that is authorized to be sent !--- to infrastructure devices !--- Create a Class-Map for traffic to be policed by !--- the CoPP feature class-map match-all drop-DLSw-class match access-group 111 !--- Create a Policy-Map that will be applied to the !--- Control-Plane of the device. policy-map drop-DLSw-traffic class drop-DLSw-class drop !--- Apply the Policy-Map to the Control-Plane of the !--- device control-plane service-policy input drop-DLSw-traffic In the above CoPP example, the access control entries (ACEs) which match the potential exploit packets with the "permit" action result in these packets being discarded by the policy-map "drop" function, while packets that match the "deny" action (not shown) are not affected by the policy-map drop function. Please note that in the Cisco IOS 12.2S and 12.0S trains the policy-map syntax is different: policy-map drop-DLSw-traffic class drop-DLSw-class police 32000 1500 1500 conform-action drop exceed-action drop Additional information on the configuration and use of the CoPP feature is available at http://www.cisco.com/en/US/products/ps6642/products_white_paper0900aecd804fa16a.shtml and http://www.cisco.com/en/US/products/sw/iosswrel/ps1838/products_feature_guide09186a008052446b.html. Using Infrastructure ACLs at Network Boundary +-------------------------------------------- Although it is often difficult to block traffic transiting your network, it is possible to identify traffic that should never be allowed to target your infrastructure devices and block that traffic at the border of your network. iACLs are a network security best practice and should be considered as a long-term addition to good network security as well as a workaround for this specific vulnerability. The iACL example shown below should be included as part of the deployed infrastructure access-list that will protect all devices with IP addresses in the infrastructure IP address range. If FST is not used, protocol 91 may be completely filtered. Additionally, if UDP is disabled with the "dlsw udp-disable" command, UDP port 2067 may also be completely filtered. !--- Permit DLSw (UDP port 2067 and IP protocol 91) packets !--- from trusted hosts destined to infrastructure addresses. access-list 150 permit udp TRUSTED_HOSTS MASK INFRASTRUCTURE_ADDRESSES MASK eq 2067 access-list 150 permit 91 TRUSTED_HOSTS MASK INFRASTRUCTURE_ADDRESSES MASK !--- Deny DLSw (UDP port 2067 and IP protocol 91) packets from !--- all other sources destined to infrastructure addresses. access-list 150 deny udp any INFRASTRUCTURE_ADDRESSES MASK eq 2067 access-list 150 deny 91 any INFRASTRUCTURE_ADDRESSES MASK !--- Permit/deny all other Layer 3 and Layer 4 traffic in accordance !--- with existing security policies and configurations !--- Permit all other traffic to transit the device. access-list 150 permit ip any any interface serial 2/0 ip access-group 150 in The white paper entitled "Protecting Your Core: Infrastructure Protection Access Control Lists" presents guidelines and recommended deployment techniques for infrastructure protection access lists.
