Description

Cisco TelePresence Recording Server contains a vulnerability that could allow an unauthenticated, remote attacker to execute arbitrary commands with elevated privileges.

The vulnerability is due to errors when processing malicious requests.  An unauthenticated, remote attacker could exploit this vulnerability by sending malicious requests to a targeted device.  If successful, the attacker could execute arbitrary commands on the device with elevated privileges.

Cisco has confirmed this vulnerability in a security advisory and has released updated software.

 
Warning Indicators

Cisco TelePresence Recording Server software versions prior to 1.8.0 are vulnerable. 

 
IntelliShield Analysis

To be successful, an attacker would need access to an adjacent network and be able to send malicious requests to an affected device.  This device would most likely reside on an internal, trusted network, making a random attack less likely to occur.

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 Cisco bug ID CSCth85804 at the following link: cisco-sa-20120711-ctrs

 
Impact

An unauthenticated, remote attacker could exploit this vulnerability to perform a command injection attack, allowing the attacker to execute arbitrary commands with elevated privileges.

 
Technical Information

The vulnerability is in the administrative web interface and is triggered by malicious requests sent to the affected device.

An unauthenticated, remote attacker could perform a command injection attack by sending malicious requests to an affected device.  When the malicious requests are processed, the attacker could execute arbitrary commands with elevated privileges.

 
Safeguards

Administrators are advised to apply the appropriate updates.

Administrators are advised to allow only trusted users to have network access.

Administrators are advised to allow only privileged users to access administration or management systems.
