Version Summary:Cisco Wide Area Application Services (WAAS) Mobile contains a vulnerability that could allow an unauthenticated, remote attacker to execute arbitrary code on a targeted system. Updates are available.
 
 
Description
A vulnerability in the web management interface of Cisco WAAS Mobile server could allow an unauthenticated, remote attacker to execute arbitrary code on the affected system.

The vulnerability is due to insufficient validation of user-supplied data in the body of an HTTP POST request. An attacker could exploit this vulnerability by crafting an HTTP POST request for content upload that would result in an uncontrolled directory traversal. An exploit could allow the attacker to execute arbitrary code on the WAAS Mobile server with the privileges of the IIS web server.

Cisco has confirmed the vulnerability in a security advisory and released software updates.
 
Warning Indicators
Cisco WAAS Mobile versions prior to 3.5.5 are vulnerable.
 
IntelliShield Analysis
To exploit the vulnerability, the attacker must be able to send malicious HTTP requests to the web management console. Environments that block access to the devices or the web management console could prevent attempts to exploit the vulnerability, reducing the risk of exploitation.

Only server devices are affected by the vulnerability; client software is not affected.
