IntelliShield ID:26342
Version:1
First Published:2012 July 11 16:19 GMT
Last Published:2012 July 11 16:19 GMT
Port: Not available

Version Summary:

Cisco TelePresence Multipoint Switch contains a vulnerability that could allow an unauthenticated, remote attacker to execute arbitrary code on an affected system.  Updates are available.

 
 
Description

Cisco TelePresence Multipoint Switch contains a vulnerability that could allow an unauthenticated,  remote attacker to execute arbitrary code on an affected system.

The vulnerability is due to insufficient sanitization of user-supplied input by the affected software.  An unauthenticated, remote attacker could exploit this vulnerability by sending specially crafted Cisco Discovery Protocol packets to a targeted device.  If successful, the attacker could execute arbitrary code with elevated privileges on the system.

Cisco has confirmed the vulnerability in a security advisory and released software updates.

 
Warning Indicators

Cisco TelePresence Multipoint Switch software versions prior to 1.9.0 are vulnerable.

 
IntelliShield Analysis

To exploit this vulnerability, an attacker must have a way to submit Ethernet frames directly to an affected device.  In most enterprise environments, these devices would be place on internal, trusted networks with firewall restrictions.  This access requirement would likely decrease the chances of a successful exploit.

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 CSCtz40965 at the following link: cisco-sa-20120711-ctms

 
Impact

An unauthenticated, remote attacker could exploit the vulnerability to execute arbitrary code with elevated privileges on an affected system.  Successful exploitation could allow the attacker to cause a complete system compromise.

 
Technical Information

The vulnerability is due to insufficient sanitization of user-supplied input by the affected software while processing malformed Cisco Discovery Protocol packets.

An unauthenticated, remote attacker could exploit this vulnerability by sending crafted Cisco Discovery Protocol packets to the affected software.  When processed, the packets could allow an attacker to execute arbitrary code 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 may consider using IP-based access control lists (ACLs) to allow only trusted systems to access the affected systems.

Administrators are advised to monitor affected systems.
