Version Summary:Cisco Video Surveillance Manager contains a vulnerability that could allow an unauthenticated, remote attacker to conduct directory traversal attacks. Updates are available.
 
 
Description
A vulnerability in Cisco Video Surveillance Manager (VSM) could allow an unauthenticated, remote attacker to conduct directory traversal attacks and gain access to sensitive information.

The vulnerability is due to improper validation of user-supplied input processed by the affected software. An unauthenticated, remote attacker could exploit this vulnerability by convincing a targeted user to follow a crafted URL. If successful, the attacker could launch directory traversal attacks on the targeted device and access sensitive information from arbitrary files on the system. The attacker could use the information to conduct further attacks.

Cisco has confirmed the vulnerability in a security advisory and released software updates.
 
Warning Indicators
Cisco VSM versions prior to 7.0.0 are affected.
 
IntelliShield Analysis
To exploit the vulnerability, the attacker may provide a link that directs a user to a malicious site and use misleading language or instructions to persuade the user to follow the provided link.

Cisco indicates through the CVSS score that functional exploit code exists; however, the code is not known to be publicly available.
 
Vendor Announcements
Cisco has released a security advisory for bug ID CSCsv37163 at the following link: cisco-sa-20130724-vsm
 
Impact
An unauthenticated, remote attacker could exploit this vulnerability to access sensitive information on a targeted system. An attacker could use the information to gain administrative control on the device, which could be used to launch further attacks.
 
Technical Information
The vulnerability is due to insufficient validation of user-supplied input processed by the affected software.

An unauthenticated, remote attacker could exploit this vulnerability by convincing a user to follow a crafted URL on an affected system. If successful, the attacker could conduct directory traversal attacks that the attacker could use to gain unauthorized access to sensitive information on the system. The attacker could use the information to conduct further attacks on an affected device.
 
Safeguards
Administrators are advised to apply the appropriate updates.

Users are advised not to open email messages from suspicious or unrecognized sources. If users cannot verify that links or attachments included in email messages are safe, they are advised not to open them.

The Cisco Applied Intelligence team has created the following companion document to guide administrators in identifying and mitigating attempts to exploit this vulnerability prior to applying updated software: Identifying and Mitigating Exploitation of Multiple Vulnerabilities in the Cisco Video Surveillance Manager

Administrators may consider following the suggested mitigation or remediation steps as described in Securing Cisco Video Surveillance Manager Release 6.x: Best Practices and Recommendations, and removing the Broadware sample code as described in the "Workarounds" section of the security advisory.

Administrators are advised to monitor affected systems.
