TITLE

Cisco Video Surveillance Stream Manager Service disruption in (DoS) Vulnerabilities

DESCRIPTION

The Cisco Video Surveillance Stream Manager firmware before 5.3, as used on Cisco Video Surveillance Services Platforms and Video Surveillance Integrated Services Platforms, allows remote attackers to cause a denial of service (reboot) via a malformed payload in a UDP packet to port 37000, related to the xvcrman process, aka Bug ID CSCsj47924. The problem is Bug ID : CSCsj47924 It is a problem.Port by third party 37000 To UDP Denial of service via malformed payload in packet (DoS) There is a possibility of being put into a state. An attacker can exploit this issue to trigger an affected device to reboot, causing denial-of-service conditions. This issue is documented by Cisco Bug ID CSCsj47924. Cisco Video Surveillance 2500 Series IP Cameras contain an information disclosure vulnerability that could allow an authenticated user to view any file on a vulnerable camera. Cisco has released free software updates that address these vulnerabilities. There are no workarounds that mitigate these vulnerabilities. An attacker could exploit this vulnerability by sending a crafted packet to UDP port 37000, which could cause the crash of a critical process and result in a system reboot. An authenticated user may be able to access a vulnerable camera and view any file through the embedded web server on TCP ports 80 (HTTP) and/or 443 (HTTPS), depending on the camera configuration. This vulnerability is documented in Cisco Bug IDs CSCsu05515 and CSCsr96497 (Wireless Cameras) and has been assigned Common Vulnerabilities and Exposures (CVE) identifier CVE-2009-2046. 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 CSCsj47924 - Malformed payload to xvcrman process causes reboot 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 CSCsu05515 - SD Camera Web Server Will Display any File on System CVSS Base Score - 6.8 Access Vector - Network Access Complexity - Low Authentication - Single Confidentiality Impact - Complete Integrity Impact - None Availability Impact - None CVSS Temporal Score - 5.6 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed CSCsr96497 - Wireless Camera HTTP Server Will Display any File on System CVSS Base Score - 6.8 Access Vector - Network Access Complexity - Low Authentication - Single Confidentiality Impact - Complete Integrity Impact - None Availability Impact - None CVSS Temporal Score - 5.6 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed Impact ====== Successful exploitation of the Cisco Video Surveillance Stream Manager firmware vulnerability could cause a system reboot. Repeated exploitation may result in an extended DoS condition, which could prevent administrators from viewing video surveillance feeds. Successful exploitation of the Cisco Video Surveillance 2500 Series IP Cameras vulnerability could allow an authenticated user to view any file on a vulnerable camera. This vulnerability could allow a non-privileged user to obtain privileged access. 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. On Cisco Video Surveillance 2500 Series IP Cameras, administrators are advised to restrict access to TCP ports 80 and 443 to trusted hosts. Additional mitigations that can be deployed on Cisco devices within the network are available in the Cisco Applied Mitigation Bulletin companion document for this advisory, which is available at the following link: http://www.cisco.com/warp/public/707/cisco-amb-20090624-video.shtml Obtaining Fixed Software ======================== Cisco has released free software updates that address these vulnerabilities. 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/en/US/docs/general/warranty/English/EU1KEN_.html or as otherwise set forth at Cisco.com Downloads at: http://www.cisco.com/public/sw-center/sw-usingswc.shtml Do not contact psirt@cisco.com or security-alert@cisco.com for software upgrades.
