Summary

Multiple unspecified vulnerabilities in the CSRadius service in Cisco Secure Access Control Server (ACS) for Windows before 4.1 and ACS Solution Engine before 4.1 allow remote attackers to cause a denial of service (crash) via a crafted RADIUS Access-Request packet. At least one issue is a heap-based buffer overflow involving the Tunnel-Password attribute.

Risk Assessment

The vulnerability can lead to unavailability of the RADIUS authentication service, preventing users from accessing the network and systems, and potentially disrupting IT infrastructure operations.

Recommendation

Update Cisco Secure ACS for Windows and ACS Solution Engine to version 4.1 or later as soon as possible. Until patching, restrict access to the CSRadius service to trusted IP addresses only.
