Version Summary:Cisco Identity Services Engine contains a vulnerability that could allow an authenticated, remote attacker to execute arbitrary commands. Updates are available.
 
 
Description
A vulnerability in the web framework of Cisco Identity Services Engine (ISE) could allow an authenticated, remote attacker to execute arbitrary commands on the underlying operating system.

The vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by injecting arbitrary commands and execute the affected function. An exploit could allow the attacker to run arbitrary commands on the affected system with the privilege of the root user.

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