Security readout for executives and security teams

This old issue could let an outside user learn the real internal IP address of an FTP server behind Cisco Secure PIX Firewall 5.2(2). It is an information disclosure weakness, not a confirmed remote code execution issue. Exposure appears limited to legacy Cisco Secure PIX Firewall 5.2(2) deployments protecting reachable FTP services. The source bundle does not identify broader affected versions or current supported products. Low to moderate for most organizations unless legacy PIX firewalls and exposed FTP services remain in production. Treat confirmed exposure as a legacy perimeter cleanup item. Mitigation focus: Check Cisco or vendor historical guidance for PIX 5.2(2) remediation details.; Retire or replace any internet-facing legacy PIX 5.2(2) firewall.; Limit external FTP exposure where business use does not require it..
