Google Chrome before 9.0.597.107 does not properly handle tables, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via unknown vectors that lead to a "stale node.". Google Chrome is prone to multiple vulnerabilities. Attackers may exploit these issues to execute arbitrary code in the context of the browser or cause denial-of-service conditions; other attacks are also possible. Chrome versions prior to 9.0.597.107 are vulnerable. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - ------------------------------------------------------------------------- Debian Security Advisory DSA-2189-1 security@debian.org http://www.debian.org/security/ Giuseppe Iuculano March 10, 2011 http://www.debian.org/security/faq - ------------------------------------------------------------------------- Package : chromium-browser Vulnerability : several Problem type : remote Debian-specific: no CVE ID : CVE-2011-1108 CVE-2011-1109 CVE-2011-1113 CVE-2011-1114 CVE-2011-1115 CVE-2011-1121 CVE-2011-1122 Several vulnerabilities were discovered in the Chromium browser.

Buffer overflow in the PPP Access Concentrator (PPPAC) on the SEIL/x86 with firmware 1.00 through 1.61, SEIL/B1 with firmware 1.00 through 3.11, SEIL/X1 with firmware 1.00 through 3.11, SEIL/X2 with firmware 1.00 through 3.11, SEIL/Turbo with firmware 1.80 through 2.10, and SEIL/neu 2FE Plus with firmware 1.80 through 2.10 might allow remote attackers to execute arbitrary code via a PPPoE packet. SEIL Series routers contain a buffer overflow vulnerability. Accoding to the developer, all versions of SEIL/86, SEIL/B1, SEIL/X1, SEIL/X2 3.00 through 3.11 process PPPoE packets in a non-administrative mode of operation, therefore the affect of this vulnerability is limited to the PPPAC service being stopped. A security vulnerability exists in the SEIL router that allows malicious users to compromise the target system. Sending a specially crafted message can execute arbitrary code in the context of the application. Multiple SEIL products, including SEIL/x86, SEIL/B1, SEIL/X1, SEIL/X2, Turbo, and neu 2FE Plus are prone to a buffer-overflow vulnerability. Failed exploit attempts will result in a denial-of-service condition. SEIL Router is a router produced by Japanese SEIL manufacturer. ---------------------------------------------------------------------- Meet Secunia @ Microsoft Management Summit (MMS) in Las Vegas, USA (21-25 March). http://secunia.com/company/events/mms_2011/ ---------------------------------------------------------------------- TITLE: SEIL Routers PPP Access Concentrator Buffer Overflow Vulnerability SECUNIA ADVISORY ID: SA43494 VERIFY ADVISORY: Secunia.com http://secunia.com/advisories/43494/ Customer Area (Credentials Required) https://ca.secunia.com/?page=viewadvisory&vuln_id=43494 RELEASE DATE: 2011-03-18 DISCUSS ADVISORY: http://secunia.com/advisories/43494/#comments AVAILABLE ON SITE AND IN CUSTOMER AREA: * Last Update * Popularity * Comments * Criticality Level * Impact * Where * Solution Status * Operating System / Software * CVE Reference(s) http://secunia.com/advisories/43494/ ONLY AVAILABLE IN CUSTOMER AREA: * Authentication Level * Report Reliability * Secunia PoC * Secunia Analysis * Systems Affected * Approve Distribution * Remediation Status * Secunia CVSS Score * CVSS https://ca.secunia.com/?page=viewadvisory&vuln_id=43494 ONLY AVAILABLE WITH SECUNIA CSI AND SECUNIA PSI: * AUTOMATED SCANNING http://secunia.com/vulnerability_scanning/personal/ http://secunia.com/vulnerability_scanning/corporate/wsus_sccm_3rd_third_party_patching/ DESCRIPTION: A vulnerability has been reported in SEIL Routers, which can be exploited by malicious people to compromise a vulnerable system.

If a Virtual Switching System (VSS) is used to allow two physical Cisco Catalyst 6500 Series Switches to operate as a single logical virtual switch, the "show module switch all" command can display the software version of all FWSMs that belong to switch 1 and switch 2. The output from this command will be similar to the output from "show module <slot number>" but will include module information for the modules in each switch in the VSS. The FWSM offers firewall services with stateful packet filtering and deep packet inspection. Each row of the following Cisco FWSM software table describes a major Cisco FWSM software train and the earliest possible release in that train that contains the fix (the "First Fixed Release") and the anticipated date of availability (if not currently available) in the First Fixed Release column. A device that is running a release that is earlier than the release in a specific column (earlier than the First Fixed Release) is known to be vulnerable. Cisco has released free software updates that address these vulnerabilities. This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20110223-asa.shtml. A separate Cisco Security Advisory has been published to disclose the vulnerability that affects the Cisco FWSM. That advisory is available at http://www.cisco.com/warp/public/707/cisco-sa-20110223-fwsm.shtml. Affected versions of Cisco ASA Software vary depending on the specific vulnerability. Vulnerable Products +------------------ For specific version information, refer to the Software Versions and Fixes section of this advisory. Transparent Firewall Packet Buffer Exhaustion Vulnerability +---------------------------------------------------------- A packet buffer exhaustion vulnerability affects multiple versions of Cisco ASA Software when a security appliance is configured to operate in the transparent firewall mode. Transparent firewall mode is enabled on the appliance if the command "firewall transparent" is present in the configuration. The default firewall mode is routed, not transparent. Administrators can determine if SCCP inspection is enabled by issuing the "show service-policy | include skinny" command and confirming that output, such as what is displayed in the following example, is returned. ciscoasa# show service-policy | include skinny Inspect: skinny, packet 0, drop 0, reset-drop 0 Alternatively, a device that has SCCP inspection enabled has a configuration similar to the following: class-map inspection_default match default-inspection-traffic ! policy-map global_policy class inspection_default ... inspect skinny ... ! service-policy global_policy global Note: The service policy could also be applied to a specific interface instead of globally, which is displayed in the previous example. SCCP inspection is enabled by default. The following example displays an affected configuration (Cisco ASA Software version 8.0 and 8.1): router rip ... ! phone-proxy <instance name> media-termination address <IP address> ... <Rest of phone proxy feature configuration> Or (Cisco ASA Software version 8.2 and later): router rip ... ! media-termination <instance name> address <IP address> ! <Rest of phone proxy feature configuration> A security appliance is vulnerable if it is processing RIP messages ("router rip") and if a global media termination address is configured for the Cisco Phone Proxy feature (refer to previous example). Note that Cisco ASA Software versions 8.0 and 8.1 only allow a global media termination address. However, in Cisco ASA Software version 8.2 and later, it is possible to tie a media termination address to an interface. This configuration, which is accomplished by issuing the command "address <IP address> interface <interface name>" in media termination configuration mode, is not affected. Neither RIP nor the Cisco Phone Proxy feature is enabled by default. An affected configuration consists of the following minimum commands: crypto ca trustpoint <trustpoint name> keypair <keypair name> crl configure crypto ca server crypto ca certificate chain <trustpoint name> certificate ca 01 ... ! http server enable The local CA server is not enabled by default. Because Cisco PIX 500 Series Security Appliances reached the end of software maintenance releases milestone on July 28, 2009, no further software releases will be available. For more information, refer to the End of Life announcement at http://www.cisco.com/en/US/prod/collateral/vpndevc/ps5708/ps5709/ps2030/end_of_life_notice_cisco_pix_525_sec_app.html. How to Determine Software Versions +--------------------------------- To determine whether a vulnerable version of Cisco ASA Software is running on an appliance, administrators can issue the "show version" command. It offers firewall, intrusion prevention system (IPS), anti-X, and virtual private network (VPN) services. The number of available packet buffers may decrease when a security appliance receives IPv6 traffic and is not configured for IPv6 operation. IPv6 transit traffic does not cause a problem. Administrators can check packet buffer utilization by issuing the command "show blocks" and inspecting the output for the number of available 1,550-byte blocks. If the number of blocks is zero (indicated by 0 in the CNT column), then the security appliance may be experiencing this issue. For example: ciscoasa# show blocks SIZE MAX LOW CNT 0 400 360 400 4 200 199 199 80 400 358 400 256 1412 1381 1412 1550 6274 0 0 ... This vulnerability is documented in Cisco bug ID CSCtj04707 and has been assigned Common Vulnerabilities and Exposures (CVE) ID CVE-2011-0393. Appliances are only vulnerable if SCCP inspection is enabled. Only transit traffic can trigger this vulnerability; traffic that is destined to the appliance will not trigger the vulnerability. This vulnerability is documented in Cisco bug ID CSCtg69457 and has been assigned Common Vulnerabilities and Exposures (CVE) ID CVE-2011-0394. Appliances are vulnerable only if both RIP and the Cisco Phone Proxy feature are enabled. Note: the affected configuration requires that a global media termination address is configured, which is the only possible configuration option in Cisco ASA Software versions 8.0 and 8.1. However, it is possible to tie a media termination address to an interface in Cisco ASA Software version 8.2 and later. This configuration is not vulnerable. This vulnerability is documented in Cisco bug ID CSCtg66583 and has been assigned Common Vulnerabilities and Exposures (CVE) ID CVE-2011-0395. but not system:) when the security appliance is configured as a local CA server. No authentication is required. File systems could contain sensitive information, such as backup device configurations (which may contain passwords or shared secrets), Cisco ASA Software images, or digital certificates. This vulnerability is documented in Cisco bug ID CSCtk12352 and has been assigned Common Vulnerabilities and Exposures (CVE) ID CVE-2011-0396.

The CGI implementation on Cisco TelePresence endpoint devices with software 1.2.x through 1.6.x allows remote authenticated users to execute arbitrary commands via a malformed request, related to "command injection vulnerabilities," aka Bug ID CSCth24671. Cisco TelePresence is a telepresence conferencing solution developed by Cisco. To exploit these vulnerabilities, an attacker must send a malformed request to the affected device's TCP port 443. An attacker must perform three TCP handshakes and establish a legitimate session to exploit these vulnerabilities. Cisco TelePresence endpoint devices are prone to multiple vulnerabilities. An attacker can exploit these issues to execute arbitrary commands, disclose potentially sensitive information, or cause denial-of-service conditions. The solution provides components such as audio and video spaces, which can provide remote participants with a "face-to-face" virtual meeting room effect. The defect that is related to each component is covered in each associated advisory. To determine the current version of software that is running on the endpoint, access the device via SSH and issue the show version command. The output should resemble the following example. The version that is active on the system will be marked by an asterisk character (*). admin: show version primary Factory CTS 1.4.2(2194) *Slot 1 CTS 1.7.1(4750) P1 Slot 2 CTS 1.6.2(2835) P1 admin: In the preceding example, the system has versions 1.4.2, 1.6.2, and 1.7.1 loaded on the device and version 1.7.1 is currently active. A device is affected only by vulnerabilities that are present in the active software version. Products Confirmed Not Vulnerable +-------------------------------- No other Cisco products are currently known to be affected by these vulnerabilities. Details ======= The Cisco TelePresence solution allows for immersive, in-person communication and collaboration over the network with colleagues, prospects, and partners even when they are located in opposite hemispheres. Because the vulnerability is within a UDP based service, the attacker would not be required to perform a handshake prior to making the crafted request. However, due to the fact that this is an information disclosure issue the attacker would need to supply a valid return IP address to retrieve the information. An attacker with the ability to impersonate a Cisco TelePresence Manager system could remotely inject an invalid IP address into a configuration file that could cause a critical service on the device to crash. An endpoint affected by this issue will remain unusable until it has been manually restored to a known good state. Restoration of service may require an administrator to reload software on the affected device. The issue may require that the attacker perform an ARP spoofing or other form of impersonation attack. This vulnerability could allow an unauthenticated, adjacent attacker to trigger a buffer overflow condition. Because Cisco Discovery Protocol functions at the Data-Link (L2) layer, an attacker must submit an Ethernet frame directly to an affected device. This scenario may be possible when affected systems are part of a bridged network or connected to a nonpartitioned device such as a network hub. 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 Cisco 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 * CSCtb31640 - Unauthenticated CGI Access CVSS Base Score - 10 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - Complete Integrity Impact - Complete Availability Impact - Complete CVSS Temporal Score - 8.3 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed * CSCtb31685 - CGI Command Injection CVSS Base Score - 9.0 Access Vector - Network Access Complexity - Low Authentication - Single Confidentiality Impact - Complete Integrity Impact - Complete Availability Impact - Complete CVSS Temporal Score - 7.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed * CSCtb31659 - CGI Command Injection CVSS Base Score - 9.0 Access Vector - Network Access Complexity - Low Authentication - Single Confidentiality Impact - Complete Integrity Impact - Complete Availability Impact - Complete CVSS Temporal Score - 7.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed * CSCth24671 - CGI Command Injection CVSS Base Score - 9.0 Access Vector - Network Access Complexity - Low Authentication - Single Confidentiality Impact - Complete Integrity Impact - Complete Availability Impact - Complete CVSS Temporal Score - 7.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed * CSCte43876 - TFTP Information Disclosure CVSS Base Score - 10 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - Complete Integrity Impact - Complete Availability Impact - Complete CVSS Temporal Score - 8.3 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed * CSCth03605 - Malicious IP Address Injection 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 * CSCtb52587 - XML-RPC Command Injection CVSS Base Score - 8.3 Access Vector - Adjacent Network Access Complexity - Low Authentication - None Confidentiality Impact - Complete Integrity Impact - Complete Availability Impact - Complete CVSS Temporal Score - 6.9 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed * CSCtd75754 - Cisco Discovery Protocol Remote Code Execution CVSS Base Score - 7.9 Access Vector - Adjacent Network Access Complexity - Medium Authentication - None Confidentiality Impact - Complete Integrity Impact - Complete Availability Impact - Complete CVSS Temporal Score - 6.5 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed Impact ====== Successful exploitation of the Unauthenticated CGI Access (CSCtb31640) vulnerability could allow an unauthenticated, remote attacker to take complete control of an affected device or system. Successful exploitation of the TFTP Information Disclosure (CSCte43876) vulnerability could allow an unauthenticated, remote attacker to take complete control of an affected system. Successful exploitation of the Malicious IP Address Injection (CSCth03605) vulnerability could allow an unauthenticated, remote attacker to cause a persistent denial of service condition on an affected system. Successful exploitation of the XML-RPC Command Injection (CSCtb52587) vulnerability could allow an unauthenticated, adjacent attacker to take complete control of an affected system. Successful exploitation of the Cisco Discovery Protocol Remote Code Execution (CSCtd75754) vulnerability could allow an unauthenticated, adjacent attacker to take complete control of an affected system. 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.

The TFTP implementation on Cisco TelePresence endpoint devices with software 1.2.x through 1.5.x, 1.6.0, and 1.6.1 allows remote attackers to obtain sensitive information via a GET request, aka Bug ID CSCte43876. The problem is Bug ID CSCte43876 It is a problem.By a third party GET Important information may be obtained through a request. Cisco TelePresence is a telepresence conferencing solution developed by Cisco. The attacker must send a TFTP GET request to the UDP port 69 of the affected device. An attacker can exploit these issues to execute arbitrary commands, disclose potentially sensitive information, or cause denial-of-service conditions. The solution provides components such as audio and video spaces, which can provide remote participants with a "face-to-face" virtual meeting room effect. This advisory addresses Cisco TelePresence endpoint devices and details the following vulnerabilities: * Unauthenticated Common Gateway Interface (CGI) Access * CGI Command Injection * TFTP Information Disclosure * Malicious IP Address Injection * XML-Remote Procedure Call (RPC) Command Injection * Cisco Discovery Protocol Remote Code Execution Duplicate Issue Identification in Other Cisco TelePresence Advisories +-------------------------------------------------------------------- The Cisco Discovery Protocol Remote Code Execution vulnerability affects Cisco TelePresence endpoint devices, Manager, Multipoint Switch, and Recording Server. The defect that is related to each component is covered in each associated advisory. To determine the current version of software that is running on the endpoint, access the device via SSH and issue the show version command. The output should resemble the following example. The version that is active on the system will be marked by an asterisk character (*). admin: show version primary Factory CTS 1.4.2(2194) *Slot 1 CTS 1.7.1(4750) P1 Slot 2 CTS 1.6.2(2835) P1 admin: In the preceding example, the system has versions 1.4.2, 1.6.2, and 1.7.1 loaded on the device and version 1.7.1 is currently active. A device is affected only by vulnerabilities that are present in the active software version. Products Confirmed Not Vulnerable +-------------------------------- No other Cisco products are currently known to be affected by these vulnerabilities. Details ======= The Cisco TelePresence solution allows for immersive, in-person communication and collaboration over the network with colleagues, prospects, and partners even when they are located in opposite hemispheres. Unauthenticated CGI Access Multiple CGI command injection vulnerabilities exist in Cisco TelePresence endpoint devices that could allow a remote, authenticated attacker to execute arbitrary commands with elevated privileges. An attacker must perform a three-way TCP handshake and establish a valid session to exploit this vulnerability. * Cisco TelePresence endpoint - CSCtb31640 ( registered customers only) has been assigned the CVE identifier CVE-2011-0372 CGI Command Injection Multiple CGI command injection vulnerabilities exist in Cisco TelePresence endpoint devices that could allow a remote, authenticated attacker to execute arbitrary commands with elevated privileges. An attacker must perform a three-way TCP handshake and establish a valid session to exploit these vulnerabilities: * Cisco TelePresence endpoint - CSCtb31685 ( registered customers only) has been assigned the CVE identifier CVE-2011-0373. Because the vulnerability is within a UDP based service, the attacker would not be required to perform a handshake prior to making the crafted request. However, due to the fact that this is an information disclosure issue the attacker would need to supply a valid return IP address to retrieve the information. An attacker with the ability to impersonate a Cisco TelePresence Manager system could remotely inject an invalid IP address into a configuration file that could cause a critical service on the device to crash. An endpoint affected by this issue will remain unusable until it has been manually restored to a known good state. Restoration of service may require an administrator to reload software on the affected device. An attacker must perform a three-way TCP handshake and establish a valid session to exploit this vulnerability. An attacker must perform a three-way TCP handshake and establish a valid session to exploit this vulnerability. The issue may require that the attacker perform an ARP spoofing or other form of impersonation attack. This vulnerability could allow an unauthenticated, adjacent attacker to trigger a buffer overflow condition. To exploit this vulnerability, the attacker must submit a malicious Cisco Discovery Protocol packet to an affected system. Because Cisco Discovery Protocol functions at the Data-Link (L2) layer, an attacker must submit an Ethernet frame directly to an affected device. This scenario may be possible when affected systems are part of a bridged network or connected to a nonpartitioned device such as a network hub.

The XML-RPC implementation on Cisco TelePresence endpoint devices with software 1.2.x through 1.5.x allows remote attackers to execute arbitrary commands via a TCP request, related to a "command injection vulnerability," aka Bug ID CSCtb52587. The problem is Bug ID CSCtb52587 It is a problem.By a third party TCP An arbitrary command may be executed through a request. Cisco TelePresence is a telepresence conferencing solution developed by Cisco. An attacker can exploit these issues to execute arbitrary commands, disclose potentially sensitive information, or cause denial-of-service conditions. The solution provides components such as audio and video spaces, which can provide remote participants with a "face-to-face" virtual meeting room effect. The defect that is related to each component is covered in each associated advisory. To determine the current version of software that is running on the endpoint, access the device via SSH and issue the show version command. The output should resemble the following example. The version that is active on the system will be marked by an asterisk character (*). admin: show version primary Factory CTS 1.4.2(2194) *Slot 1 CTS 1.7.1(4750) P1 Slot 2 CTS 1.6.2(2835) P1 admin: In the preceding example, the system has versions 1.4.2, 1.6.2, and 1.7.1 loaded on the device and version 1.7.1 is currently active. A device is affected only by vulnerabilities that are present in the active software version. Products Confirmed Not Vulnerable +-------------------------------- No other Cisco products are currently known to be affected by these vulnerabilities. Details ======= The Cisco TelePresence solution allows for immersive, in-person communication and collaboration over the network with colleagues, prospects, and partners even when they are located in opposite hemispheres. To exploit these vulnerabilities, an attacker must submit a malformed request to an affected device via TCP port 8082. An attacker must perform a three-way TCP handshake and establish a valid session to exploit this vulnerability. To exploit these vulnerabilities, an attacker must submit a malformed request to an affected device via TCP port 443. An attacker must perform a three-way TCP handshake and establish a valid session to exploit these vulnerabilities: * Cisco TelePresence endpoint - CSCtb31685 ( registered customers only) has been assigned the CVE identifier CVE-2011-0373. The attacker would need to have the ability to submit a TFTP GET request via UDP port 69 to the affected device. Because the vulnerability is within a UDP based service, the attacker would not be required to perform a handshake prior to making the crafted request. However, due to the fact that this is an information disclosure issue the attacker would need to supply a valid return IP address to retrieve the information. An attacker with the ability to impersonate a Cisco TelePresence Manager system could remotely inject an invalid IP address into a configuration file that could cause a critical service on the device to crash. An endpoint affected by this issue will remain unusable until it has been manually restored to a known good state. Restoration of service may require an administrator to reload software on the affected device. The attacker would need the ability to submit a malformed SOAP request to an affected device via TCP port 8081 or TCP port 9501. An attacker must perform a three-way TCP handshake and establish a valid session to exploit this vulnerability. The attacker would need the ability to submit a request to an affected system via TCP port 61441 or TCP port 61445. An attacker must perform a three-way TCP handshake and establish a valid session to exploit this vulnerability. The issue may require that the attacker perform an ARP spoofing or other form of impersonation attack. This vulnerability could allow an unauthenticated, adjacent attacker to trigger a buffer overflow condition. To exploit this vulnerability, the attacker must submit a malicious Cisco Discovery Protocol packet to an affected system. Because Cisco Discovery Protocol functions at the Data-Link (L2) layer, an attacker must submit an Ethernet frame directly to an affected device. This scenario may be possible when affected systems are part of a bridged network or connected to a nonpartitioned device such as a network hub. Vulnerability Scoring Details +---------------------------- Cisco has provided scores for the vulnerabilities in this advisory based on the Common Vulnerability Scoring System (CVSS).

To determine the current version of software that is running on the Cisco TelePresence Recording Server, SSH into the device and issue the show version active and the show version inactive commands. The output should resemble the following example: admin: show version active Active Master Version: 1.7.0.0-151 Active Version Installed Software Options: No Installed Software Options Found. admin: show version inactive Inactive Master Version: 1.6.2.0-237 Inactive Version Installed Software Options: No Installed Software Options Found. In the preceding example, the system has versions 1.6.2 and 1.7.0 loaded on the device and version 1.7.0 is currently active. A device is affected only by vulnerabilities that are present in the active software version. Products Confirmed Not Vulnerable +-------------------------------- No other Cisco products are currently known to be affected by these vulnerabilities. These vulnerabilities are independent of each other. Unauthenticated Java Servlet Access +---------------------------------- A number of sensitive Java Servlets delivered via a Java Servlet framework within the Cisco TelePresence Recording Server could allow a remote, unauthenticated attacker to perform actions that should be restricted to administrative users. To successfully exploit this vulnerability, the attacker would need the ability to submit a crafted request to an affected device on TCP port 80, TCP port 443, or TCP port 8080. An attacker must perform a three-way TCP handshake and establish a valid session to exploit these vulnerabilities. To successfully exploit this vulnerability the attacker would need the ability to submit a malformed request to an affected device via TCP port 443. An attacker must perform a three-way TCP handshake and establish a valid session to exploit these vulnerabilities. An unauthenticated, remote attacker could place content to arbitrary locations on the device by submitting crafted requests to the affected device.
