Summary
=======
A vulnerability in the restricted shell of the Cisco Identity Services Engine (ISE) that is accessible via SSH could allow an authenticated, local attacker to run arbitrary CLI commands with elevated privileges.

The vulnerability is due to incomplete input validation of the user input for CLI commands issued at the restricted shell. An attacker could exploit this vulnerability by authenticating to the targeted device and executing commands that could lead to elevated privileges. An attacker would need valid user credentials to the device to exploit this vulnerability.

Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
