CVE-2002-1978 describes a firewall bypass vulnerability in IPFilter versions 3.1.1 through 3.4.28. Remote attackers can exploit this by sending a crafted FTP command containing a "PASV" string, tricking IPFilter into misinterpreting the FTP server's response as a legitimate PASV command and thus bypassing established firewall rules. This vulnerability carries a high CVSS score of 7.5, indicating a network-based attack with low complexity that could lead to partial compromise of confidentiality, integrity, and availability. While there is no evidence of active exploitation, public exploit code, or inclusion in the KEV catalog, the vulnerability has garnered significant community discussion, suggesting awareness among security researchers.
