Vulnerability Note VU#952422

Cisco Identity Services Engine contains an input validation vulnerability

Original Release date: 28 Oct 2013 | Last revised: 12 Nov 2013


Cisco Identity Services Engine contains an input validation vulnerability (CWE-20).


CWE-20: Improper Input Validation

Cisco Identity Services Engine (ISE) contains an input validation vulnerability. The ISE device contains a TCP Dump option for analyzing traffic on the device. By using a proxy to modify the HTTP request, a remote authenticated attacker can encode commands into the vulnerable format parameter which could allow them to run arbitrary code on the affected system with the privilege of the root user.


A remote authenticated attacker may be able to execute arbitrary code as root on the device.
