Version Summary:Cisco Unified Computing System contains a vulnerability that could allow an authenticated, local attacker to execute commands on the underlying operating system with elevated privileges. Updates are available.
 
 
Description
A vulnerability in the Cisco Management Controller of the Cisco Unified Computing System could allow an authenticated, local attacker to execute commands on the underlying operation system with elevated privileges.

The vulnerability is due to improper parameter input validation. An attacker could exploit this vulnerability by providing invalid parameters to the MCTools application from the CLI of a Fabric Interconnect device. A successful exploit could allow the attacker to inject arbitrary commands to the underlying operating system with elevated privileges.

Cisco has confirmed the vulnerability in a security notice and released software updates.
 
Warning Indicators
At the time this alert was first published, Cisco Unified Computing System Software versions 1.4 and prior were vulnerable. Later releases of Cisco Unified Computing System Software may also be vulnerable.
 
IntelliShield Analysis
To exploit this vulnerability, an attacker must be able to authenticate and have local access to the targeted device. These access requirements limits 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 notice at the following link: CVE-2012-4082

Customers are advised to consult Cisco bug ID CSCtg20749 for the most complete list of affected product versions.
 
Impact
An authenticated, local attacker could exploit this vulnerability to execute arbitrary commands on the underlying operating system of a targeted device with elevated privileges. Successful exploit could result in a complete system compromise.
 
Technical Information
The vulnerability is due to improper input validation on parameters sent to the MCTools application from the CLI of a Fabric Interconnect device.

An authenticated, local attacker with access to the CLI of a Fabric Interconnect device could exploit this vulnerability by providing invalid parameters to the MCTools application. Successful exploitation could allow the attacker to inject arbitrary commands to the underlying operating system with elevated privileges, which could allow the attacker to completely compromise the targeted device.
 
Safeguards
Administrators are advised to apply the appropriate updates.

Administrators are advised to allow only trusted users to access local systems.

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

Administrators are advised to monitor affected systems.
