Vulnerability from variot
The CGI implementation on Cisco TelePresence endpoint devices with software 1.2.x through 1.5.x allows remote attackers to execute arbitrary commands via a malformed request, related to "command injection vulnerabilities," aka Bug ID CSCtb31640. The problem is Bug ID CSCtb31640 It is a problem.Arbitrary commands may be executed by a third party via a malformed request. 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 8082. 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.
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. 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.

"data": "The CGI implementation on Cisco TelePresence endpoint devices with software 1.2.x through 1.5.x allows remote attackers to execute arbitrary commands via a malformed request, related to \"command injection vulnerabilities,\" aka Bug ID CSCtb31640. The problem is Bug ID CSCtb31640 It is a problem.Arbitrary commands may be executed by a third party via a malformed request. 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\u0027s TCP port 8082. Cisco TelePresence endpoint devices are prone to multiple vulnerabilities. \nAn 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\ncomponent is covered in each associated advisory. \n\nTo determine the current version of software that is running on the\nendpoint, access the device via SSH and issue the show version\ncommand. The output should resemble the following example. The\nversion that is active on the system will be marked by an asterisk\ncharacter (*). \n\n admin: show version\n primary\n Factory CTS 1.4.2(2194)\n *Slot 1 CTS 1.7.1(4750) P1\n Slot 2 CTS 1.6.2(2835) P1\n admin:\n\nIn the preceding example, the system has versions 1.4.2, 1.6.2, and\n1.7.1 loaded on the device and version 1.7.1 is currently active. A\ndevice is affected only by vulnerabilities that are present in the\nactive software version. \n\nProducts Confirmed Not Vulnerable\n+--------------------------------\n\nNo other Cisco products are currently known to be affected by these\nvulnerabilities. \n\nDetails\n=======\n\nThe Cisco TelePresence solution allows for immersive, in-person\ncommunication and collaboration over the network with colleagues,\nprospects, and partners even when they are located in opposite\nhemispheres. \n\nAn attacker must perform a three-way TCP handshake and establish a\nvalid session to exploit these vulnerabilities:\n\n * Cisco TelePresence endpoint - CSCtb31685 ( registered customers\n only) has been assigned the CVE identifier CVE-2011-0373. \n\nBecause the vulnerability is within a UDP based service, the attacker\nwould not be required to perform a handshake prior to making the\ncrafted request. However, due to the fact that this is an information\ndisclosure issue the attacker would need to supply a valid return IP\naddress to retrieve the information. An attacker with the ability\nto impersonate a Cisco TelePresence Manager system could remotely\ninject an invalid IP address into a configuration file that could\ncause a critical service on the device to crash. An endpoint affected\nby this issue will remain unusable until it has been manually\nrestored to a known good state. Restoration of service may require an\nadministrator to reload software on the affected device. The issue may require\nthat the attacker perform an ARP spoofing or other form of\nimpersonation attack. This vulnerability could allow an unauthenticated,\nadjacent attacker to trigger a buffer overflow condition. \n\nBecause Cisco Discovery Protocol functions at the Data-Link (L2)\nlayer, an attacker must submit an Ethernet frame directly to an\naffected device. This scenario may be possible when affected systems\nare part of a bridged network or connected to a nonpartitioned device\nsuch as a network hub. \n\nVulnerability Scoring Details\n+----------------------------\n\nCisco has provided scores for the vulnerabilities in this advisory\nbased on the Common Vulnerability Scoring System (CVSS). The CVSS\nscoring in this Cisco Security Advisory is done in accordance with\nCVSS version 2.0. \n\nCVSS is a standards-based scoring method that conveys vulnerability\nseverity and helps determine urgency and priority of response. \n\nCisco has provided a base and temporal score. Customers can then\ncompute environmental scores to assist in determining the impact of\nthe vulnerability in individual networks. \n\nCisco has provided an FAQ to answer additional questions regarding\nCVSS at:\n\nhttp://www.cisco.com/web/about/security/intelligence/cvss-qandas.html\n\nCisco has also provided a CVSS calculator to help compute the\nenvironmental impact for individual networks at:\n\nhttp://intellishield.cisco.com/security/alertmanager/cvss\n\n* CSCtb31640 - Unauthenticated CGI Access\n\nCVSS Base Score - 10\n Access Vector - Network\n Access Complexity - Low\n Authentication - None\n Confidentiality Impact - Complete\n Integrity Impact - Complete\n Availability Impact - Complete\n\nCVSS Temporal Score - 8.3\n Exploitability - Functional\n Remediation Level - Official-Fix\n Report Confidence - Confirmed\n\n* CSCtb31685 - CGI Command Injection \n\nCVSS Base Score - 9.0 \n Access Vector - Network\n Access Complexity - Low\n Authentication - Single\n Confidentiality Impact - Complete\n Integrity Impact - Complete\n Availability Impact - Complete\n\nCVSS Temporal Score - 7.4\n Exploitability - Functional\n Remediation Level - Official-Fix\n Report Confidence - Confirmed\n\n* CSCtb31659 - CGI Command Injection\n\nCVSS Base Score - 9.0\n Access Vector - Network\n Access Complexity - Low\n Authentication - Single\n Confidentiality Impact - Complete\n Integrity Impact - Complete\n Availability Impact - Complete\n\nCVSS Temporal Score - 7.4\n Exploitability - Functional\n Remediation Level - Official-Fix\n Report Confidence - Confirmed\n\n* CSCth24671 - CGI Command Injection\n\nCVSS Base Score - 9.0\n Access Vector - Network\n Access Complexity - Low\n Authentication - Single\n Confidentiality Impact - Complete\n Integrity Impact - Complete\n Availability Impact - Complete\n\nCVSS Temporal Score - 7.4\n Exploitability - Functional\n Remediation Level - Official-Fix\n Report Confidence - Confirmed\n\n* CSCte43876 - TFTP Information Disclosure\n\nCVSS Base Score - 10\n Access Vector - Network\n Access Complexity - Low\n Authentication - None\n Confidentiality Impact - Complete\n Integrity Impact - Complete\n Availability Impact - Complete\n\nCVSS Temporal Score - 8.3\n Exploitability - Functional\n Remediation Level - Official-Fix\n Report Confidence - Confirmed\n\n* CSCth03605 - Malicious IP Address Injection\n\nCVSS Base Score - 7.8\n Access Vector - Network\n Access Complexity - Low\n Authentication - None\n Confidentiality Impact - None\n Integrity Impact - None\n Availability Impact - Complete\n\nCVSS Temporal Score - 6.4\n Exploitability - Functional\n Remediation Level - Official-Fix\n Report Confidence - Confirmed\n\n* CSCtb52587 - XML-RPC Command Injection\n\nCVSS Base Score - 8.3\n Access Vector - Adjacent Network\n Access Complexity - Low\n Authentication - None\n Confidentiality Impact - Complete\n Integrity Impact - Complete\n Availability Impact - Complete\n\nCVSS Temporal Score - 6.9\n Exploitability - Functional\n Remediation Level - Official-Fix\n Report Confidence - Confirmed\n\n* CSCtd75754 - Cisco Discovery Protocol Remote Code Execution\n\nCVSS Base Score - 7.9\n Access Vector - Adjacent Network\n Access Complexity - Medium\n Authentication - None\n Confidentiality Impact - Complete\n Integrity Impact - Complete\n Availability Impact - Complete\n\nCVSS Temporal Score - 6.5\n Exploitability - Functional\n Remediation Level - Official-Fix\n Report Confidence - Confirmed\n\nImpact\n======\n\nSuccessful exploitation of the Unauthenticated CGI Access\n(CSCtb31640) vulnerability could allow an unauthenticated, remote\nattacker to take complete control of an affected device or system. \n\nSuccessful exploitation of the TFTP Information Disclosure\n(CSCte43876) vulnerability could allow an unauthenticated, remote\nattacker to take complete control of an affected system. \n\nSuccessful exploitation of the Malicious IP Address Injection\n(CSCth03605) vulnerability could allow an unauthenticated, remote\nattacker to cause a persistent denial of service condition on an\naffected system. \n\nSuccessful exploitation of the XML-RPC Command Injection (CSCtb52587)\nvulnerability could allow an unauthenticated, adjacent attacker to\ntake complete control of an affected system. \n\nSuccessful exploitation of the Cisco Discovery Protocol Remote Code\nExecution (CSCtd75754) vulnerability could allow an unauthenticated,\nadjacent attacker to take complete control of an affected system. \n\nSoftware Versions and Fixes\n===========================\n\nWhen considering software upgrades, also consult \nhttp://www.cisco.com/go/psirt and any subsequent advisories to \ndetermine exposure and a complete upgrade solution. \n\nIn all cases, customers should exercise caution to be certain the\ndevices to be upgraded contain sufficient memory and that current\nhardware and software configurations will continue to be supported\nproperly by the new release.
