FTP proxy in Squid before 2.4.STABLE6 does not compare the IP addresses of control and data connections with the FTP server, which allows remote attackers to bypass firewall rules or spoof FTP server responses.

Security readout for executives and security teams

This old Squid FTP proxy flaw could let a remote party abuse FTP proxy behavior to get around firewall intent or make FTP responses appear to come from the server. The main concern is legacy infrastructure: modern estates are unlikely to run Squid before 2.4.STABLE6, but forgotten proxies can create exposure. Exposure is most likely where legacy Squid versions before 2.4.STABLE6 still proxy FTP traffic. Risk is higher if Squid is used as a firewall-enforcing boundary for FTP or where FTP server response integrity matters. Prioritize as a legacy exposure check, not an emergency unless old Squid FTP proxying is present. If found on a network boundary, remediation should be scheduled promptly because the flaw undermines firewall policy enforcement. Mitigation focus: Upgrade Squid to 2.4.STABLE6 or later where affected legacy versions remain.; Review the Squid advisory and relevant operating-system vendor errata for package-specific fixes.; Disable FTP proxying where it is no longer business-required..
