TITLE

Cisco Video Surveillance Service disruption in cameras ( Device reload ) Vulnerabilities

DESCRIPTION

Cisco Video Surveillance 2421 and 2500 series cameras with software 1.1.x and 2.x before 2.4.0 and Video Surveillance 2600 series cameras with software before 4.2.0-13 allow remote attackers to cause a denial of service (device reload) by sending crafted RTSP packets over TCP, aka Bug IDs CSCtj96312, CSCtj39462, and CSCtl80175. Cisco Video Surveillance Camera has a service disruption ( Device reload ) There is a vulnerability that becomes a condition. The problem is Bug ID CSCtj96312 , CSCtj39462 ,and CSCtl80175 It is a problem.By a third party TCP Cleverly crafted via RTSP Service interruption due to packet transmission ( Device reload ) There is a possibility of being put into a state. An attacker can exploit this issue to prevent a vulnerable device from sending video streams, and cause it to reload, triggering a denial-of-service condition. This issue is tracked by Cisco Bug IDs CSCtj96312, CSCtj39462, and CSCtl80175. An unauthenticated, remote attacker could exploit this vulnerability by sending crafted RTSP TCP packets to an affected device. Successful exploitation prevents cameras from sending video streams, subsequently causing a reboot. The camera reboot is done automatically and does not require action from an operator. Mitigations that can be deployed on Cisco devices within the network are available. This advisory is posted at: http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20111026-camera Note: Effective October 18, 2011, Cisco moved the current list of Cisco Security Advisories and Responses published by Cisco PSIRT. The new location is: http://tools.cisco.com/security/center/publicationListing You can also navigate to this page from the Cisco Products and Services menu of the Cisco Security Intelligence Operations (SIO) Portal. Following this transition, new Cisco Security Advisories and Responses will be published to the new location. Although the URL has changed, the content of security documents and the vulnerability policy are not impacted. Cisco will continue to disclose security vulnerabilities in accordance with the published Security Vulnerability Policy. To check the version of system firmware that is running on the device and to determine device model, log in to the device with the web management interface, and navigate to the Status page. This vulnerability can be exploited from both wired and wireless segments. 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 * CSCtj96312, CSCtj39462, CSCtl80175 - Cisco Video Surveillance IP Cameras RTSP Crafted Packet Vulnerability CVSS Base Score - 7.8 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete CVSS Temporal Score - 6.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed Impact ====== Successful exploitation of the vulnerability may result in DoS condition. Subsequent exploitation may result in sustained DoS condition, as the cameras will continue to reload. Software Versions and Fixes =========================== When considering software upgrades, also consult: http://www.cisco.com/go/psirt As well as 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. Mitigations that can be deployed on Cisco devices within the network are available in the Cisco Applied Intelligence companion document for this advisory, which is available at the following location: http://tools.cisco.com/security/center/content/CiscoAppliedMitigationBulletin/cisco-amb-20111026-camera Obtaining Fixed Software ======================== Cisco has released free software updates that address these vulnerabilities.
