Cisco TelePresence System Status Collection Daemon Command Execution Vulnerability

 
Threat Type:CWE-78: OS Command Injections
IntelliShield ID:32461
Version:1
First Published:2014 January 22 16:10 GMT
Last Published:2014 January 22 16:10 GMT
Port: Not available
CVE:CVE-2014-0661
Urgency:Unlikely Use
Credibility:Confirmed
Severity:Moderate Damage
CVSS Base:8.3 CVSS Calculator
CVSS Version 2.0
CVSS Temporal:6.9
 
Version Summary:Cisco TelePresence System Software contains a vulnerability that could allow an unauthenticated, adjacent attacker to execute arbitrary commands with elevated privileges. Updates are available.
 
 
Description
A vulnerability in System Status Collection Daemon (SSCD) code could allow an unauthenticated, adjacent attacker to execute arbitrary commands with the privilege of the root user.

The vulnerability is due to improper validation of parameters passed to the SSCD code via an XML-remote procedure call (RPC). An attacker could exploit this vulnerability by sending crafted XML-RPC messages. An exploit could allow the attacker to execute arbitrary calls via stack corruption with the privilege of the root user.

Cisco has confirmed the vulnerability in a security advisory and released software updates.
 
Warning Indicators
Cisco TelePresence System Software versions prior to 1.10.2(42) running on the following Cisco TelePresence System hardware platforms are affected:
  • Cisco TelePresence System 500-37
  • Cisco TelePresence System 1000
  • Cisco TelePresence System 1300-65
  • Cisco TelePresence System 3000
  • Cisco TelePresence System 3010
  • Cisco TelePresence System 3200
  • Cisco TelePresence System 3210
Cisco TelePresence System Software versions prior to 6.0.4(11) running on the following Cisco TelePresence System hardware platforms are affected:
  • Cisco TelePresence System 500-32
  • Cisco TelePresence System 1300-47
  • Cisco TelePresence System TX1310 65
  • Cisco TelePresence System TX9000
  • Cisco TelePresence System TX9200
 
IntelliShield Analysis
To exploit this vulnerability, an attacker would need access to the same broadcast or collision domain of the targeted device. This access requirement decreases the likelihood 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 CSCui32796 at the following link: cisco-sa-20140122-cts
 
Impact
An unauthenticated, adjacent attacker could exploit this vulnerability to execute arbitrary commands with root privileges. A successful exploit could result in a complete system compromise.
 
Technical Information
The vulnerability is due to insufficient validation of parameters passed to the SSCD code of the affected software via an XML-RPC.

An unauthenticated, adjacent attacker could exploit this vulnerability by sending crafted XML-RPC messages. An exploit could allow the attacker to execute arbitrary calls via stack corruption with the privilege of the root user. A successful exploit could result in a complete system compromise.
 
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.
