Technical analysis, exploit verification, and patch instructions for CVE-2002-1979 impacting watchguard legacy_rssa. Evaluated with CVSS Base Score of 7.5 (UNKNOWN).

Original NVD Description

Source: NIST NVD
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.
