Summary

=======

A vulnerability in the ACS Report component of Cisco Secure Access
Control System (ACS) could allow an unauthenticated, remote attacker to
execute arbitrary commands on an affected system. Commands executed by
the attacker are processed at the targeted user's privilege level.

The vulnerability is due to insufficient validation of the Action
Message Format (AMF) protocol. An attacker could exploit this
vulnerability by sending a crafted AMF message that contains malicious
code to a targeted user. A successful exploit could allow the attacker
to execute arbitrary commands on the ACS device.

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