Buffer overflow in Cisco PIX Firewall 5.2.x to 5.2.8, 6.0.x to 6.0.3, 6.1.x to 6.1.3, and 6.2.x to 6.2.1 allows remote attackers to cause a denial of service via HTTP traffic authentication using (1) TACACS+ or (2) RADIUS.

Security readout for executives and security teams

This flaw can crash or disrupt affected Cisco PIX firewalls when they process certain HTTP traffic authentication involving TACACS+ or RADIUS. For executives, the concern is service availability: a firewall outage can interrupt business traffic. The sources do not provide CVSS scoring or evidence of active exploitation. Exposure is likely limited to organizations still running the listed legacy Cisco PIX versions and using HTTP traffic authentication with TACACS+ or RADIUS. Internet or untrusted network reachability would increase operational risk. Prioritize if affected PIX firewalls still protect production traffic. The issue is old, but confirmed exposure could create firewall availability risk. If no listed versions remain, business urgency is low. Mitigation focus: Identify any Cisco PIX devices running the listed affected versions.; Review Cisco's vendor advisory for fixed versions and official remediation guidance.; Upgrade or replace affected PIX deployments according to Cisco guidance..
