Multiple Vulnerabilities in Cisco Secure Access Control System

Cisco Secure Access Control System (ACS) is affected by the following vulnerabilities:

Cisco Secure ACS RMI Privilege Escalation Vulernability
Cisco Secure ACS RMI Unauthenticated User Access Vulnerability

Cisco Secure ACS Operating System Command Injection Vulnerability

Cisco Secure ACS uses the Remote Method Invocation (RMI) interface for internode communication using TCP ports 2020 and 2030.

These vulnerabilities are independent of each other; a release that is affected by one of the vulnerabilities may not be affected by the other.

Cisco has released software updates that address these vulnerabilities. This advisory is available at the following link:

Network-based mitigations for the RMI-based vulnerabilities are outlined in the Cisco Applied Mitigation Bulletin: Identifying and Mitigating the Multiple Vulnerabilities in Cisco Secure Access Control System
