Technical description
WatchGuard SOHO products running firmware 5.1.6 and earlier, and Vclass/RSSA using 3.2 SP1 and earlier, allows remote attackers to bypass firewall rules by sending a PASV command string as the argument of another command to an FTP server, which generates a response that contains the string, causing IPFilter to treat the response as if it were a legitimate PASV command from the server.
Remediation
Check the references section for vendor advisories and patches from watchguard. Update legacy_rssa to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
