CVE-2002-1978 Information

Description

IPFilter 3.1.1 through 3.4.28 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.
