Version Summary:Cisco has released updates for some affected systems that addresses the Cisco TelePresence System default credentials vulnerability.
 
 
Description
A vulnerability in Cisco TelePresence System could allow a remote attacker to access the web server via a user account that is created with default credentials.

The vulnerability is due to a default user account being created at installation time. An attacker could exploit this vulnerability by remotely accessing the web server and using the default account credentials. An exploit could allow the attacker to log in with the default credentials, which gives them full administrative rights to the system.

Cisco has confirmed the vulnerability in a security advisory and has released software updates for some affected products.
 
Warning Indicators
Cisco TelePresence System Software versions 1.8.1 through 1.10.1 are vulnerable while running on the following Cisco TelePresence System models:
  • CTS 500-37
  • CTS 1300
  • CTS 1X00
  • CTS 3X00
  • CTS 30X0
Cisco TelePresence System Software versions 6.0.3 and prior are vulnerable while running on the following Cisco TelePresence models:
  • TX 1310
  • TX 9X00
  • CTS 500-32
 
IntelliShield Analysis
To exploit this vulnerability, an attacker would likely need access to trusted, internal networks in which the targeted device may reside. This access requirement could limit the likelihood of a successful exploit.
 
Vendor Announcements
Cisco has released a security advisory for bug ID CSCui43128 at the following link: cisco-sa-20130807-tp
 
Impact
A remote attacker could exploit this vulnerability to gain unauthorized access to the affected device. Successful exploitation could allow the attacker to modify system configuration and settings that could result in a complete system compromise.
 
Technical Information
The vulnerability is due to insufficient security restrictions imposed by the affected software. As a result, the password recovery administrator account is enabled by default and accessible from the web server.

A remote attacker could exploit this vulnerability by logging in with the default credentials from the web server. Successful exploitation could allow the attacker to modify the system configuration and settings, which could be used to completely compromise the targeted system.
 
Safeguards
Administrators are advised to apply the appropriate updates.

Administrators are advised to contact the vendor regarding future updates and releases.

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.

An additional workaround is available for customers using TelePresence codecs registered with Cisco Unified Communications Manager (Unified CM). Details on implementing this workaround are described in the "Workarounds" section of the vendor advisory.

Administrators are advised to monitor affected systems.
