Summary
Cisco Secure Access Control System (ACS) releases earlier than the patched 5.8 update are affected by this flaw in how Java deserialization handles user-supplied data. An unauthenticated remote attacker could exploit it to run arbitrary commands on the device with root-level privileges, giving them full control over the system.

A vulnerability in Java deserialization used by Cisco Secure Access Control System (ACS) prior to release 5.8 patch 9 could allow an unauthenticated, remote attacker to execute arbitrary commands on an affected device. The vulnerability is due to insecure deserialization of user-supplied content by the affected software. An attacker could exploit this vulnerability by sending a crafted serialized Java object. An exploit could allow the attacker to execute arbitrary commands on the device with root privileges. Cisco Bug IDs: CSCvh25988.
