Advisory ID: cisco-sa-20130724-vsm

http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20130724-vsm

Revision 1.0

For Public Release 2013 July 24 16:00  UTC (GMT)


Summary

The Cisco Video Surveillance Manager (VSM) allows operations managers and system integrators to build customized video surveillance networks to meet their needs. Cisco VSM provides centralized configuration, management, display, and control of video from Cisco and third-party surveillance endpoints. Multiple security vulnerabilities exist in versions of Cisco VSM prior to 7.0.0, which may allow an attacker to gain full administrative privileges on the system.

More information on Cisco VSM can be found at http://www.cisco.com/en/US/products/ps10818/index.html.

Cisco has released software updates that address these vulnerabilities. Workarounds that mitigate these vulnerabilities are available.

This advisory is available at the following link: http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20130724-vsm

Affected Products

Vulnerable Products

Cisco VSM versions prior to 7.0.0 are affected by the vulnerabilities disclosed in this advisory.

Products Confirmed Not Vulnerable

No other Cisco products are currently known to be affected by these vulnerabilities.

Details

Cisco VSM is affected by the following classification vulnerabilities:

    Information Disclosure Through Directory Traversal
    Cisco VSM does not properly validate user input to a number of pages, which may be used to gain access to sensitive system files. An unauthenticated, remote attacker may use a crafted URL to access sensitive system files. This vulnerability is documented in Cisco bug ID: CSCsv37163 (registered customers only) and has been assigned the Common Vulnerabilities Enumerator (CVE) ID: CVE-2013-3429.

    Insufficient Authentication to Sensitive Information
    Cisco VSM does not require authentication to access potentially sensitive information such as configuration, monitoring pages archives, and system logs. An unauthenticated, remote attacker may exploit these vulnerabilities to create, modify and remove camera feeds, archives, logs and users. These vulnerabilities are documented in Cisco bug IDs: CSCsv37288 (registered customers only) and CSCsv40169 (registered customers only) and has been assigned the CVE IDs: CVE-2013-3430 and CVE-2013-3431.

Vulnerability Scoring Details

Cisco has scored the vulnerabilities in this advisory based on the Common Vulnerability Scoring System (CVSS). The CVSS scoring in this security advisory is in accordance with CVSS version 2.0.

CVSS is a standards-based scoring method that conveys vulnerability severity and helps organizations determine the urgency and priority of a response.

Cisco has provided a base and temporal score. Customers can also compute environmental scores that help determine the impact of the vulnerability in their own networks.

Cisco has provided additional information regarding CVSS at the following link:

http://www.cisco.com/web/about/security/intelligence/cvss-qandas.html

Cisco has also provided a CVSS calculator to compute the environmental impact for individual networks at the following link:

Impact

Successful exploitation of the vulnerabilities may allow an unauthenticated, remote attacker to gain administrative control of Cisco VSM. This access could allow an attacker to create, modify and remove camera feeds, archives, logs and users on the VSM.

Software Versions and Fixes

Customers are encouraged to follow the suggestions in the Securing Cisco Video Surveillance Manager Release 6.x: Best Practices and Recommendations or upgrade to Cisco VSM version 7.0.1.
 
Cisco VSM 7.0 and Cisco VSM 7.0.1 releases are available to replace previous versions of Cisco VSM. Contact your Cisco representative for more information on how to obtain VSM 7.0 or 7.0.1 software and for assistance in updating from previous versions of Cisco VSM. When considering software upgrades, customers are advised to consult the Cisco Security Advisories, Responses, and Notices archive at http://www.cisco.com/go/psirt and review subsequent advisories to determine exposure and a complete upgrade solution. If the information is not clear, customers are advised to contact the Cisco Technical Assistance Center (TAC) or their contracted maintenance providers.


Workarounds

The vulnerabilities described in this document can be mitigated or remediated by following the suggestions in the guide Securing Cisco Video Surveillance Manager Release 6.x: Best Practices and Recommendations and removing the Broadware sample code.

The Broadware package name differs by the version of Cisco VSM and can be removed by issuing the command:
rpm -e [package.rpm]
The following example shows Cisco VSM software version 6.3.2(20) with the removal command:
# rpm -qa | grep -i Cisco_VSBWT
Cisco_VSBWT-6.3.2-20

# rpm -e Cisco_VSBWT-6.3.2-20

Obtaining Fixed Software

Cisco has released software updates that address the vulnerabilities described in this advisory. Prior to deploying software, customers are advised to consult their maintenance providers or check the software for feature set compatibility and known issues that are specific to their environments. Cisco VSM 7.0 and Cisco VSM 7.0.1 releases are available to replace previous versions of Cisco VSM. Contact your Cisco representative for more information on how to obtain VSM 7.0 or 7.0.1 software and for assistance in updating from previous versions of Cisco VSM.

Customers may only install and expect support for feature sets they have purchased. By installing, downloading, accessing, or otherwise using such software upgrades, customers agree to follow the terms of the Cisco software license at http://www.cisco.com/en/US/docs/general/warranty/English/EU1KEN_.html.

Customers with Service Contracts

Customers with contracts should obtain updated software through their regular update channels. For most customers, updates should be obtained through the Software Navigator on Cisco.com at http://www.cisco.com/cisco/software/navigator.html.

Customers Using Third-Party Support Organizations

Customers with Cisco products that are provided or maintained through prior or existing agreements with third-party support organizations, such as Cisco Partners, authorized resellers, or service providers, should contact that organization for assistance with the appropriate course of action.

The effectiveness of any workaround or fix depends on specific customer situations, such as product mix, network topology, traffic behavior, and organizational mission. Because of the variety of affected products and releases, customers should consult their service providers or support organizations to ensure that any applied workaround or fix is the most appropriate in the intended network before it is deployed.

Customers Without Service Contracts

Customers who purchase directly from Cisco but do not hold a Cisco service contract and customers who make purchases through third-party vendors but are unsuccessful in obtaining fixed software through their point of sale should obtain updates by contacting the Cisco Technical Assistance Center (TAC):

  • +1 800 553 2447 (toll free from within North America)
  • +1 408 526 7209 (toll call from anywhere in the world)
