This repository contains a single Metasploit module targeting a buffer overflow vulnerability (CVE-2003-0558) in LeapWare LeapFTP v2.7.3.600 for Windows. The exploit works by running a malicious FTP server that sends an overly long PASV reply to the client, triggering a buffer overflow and allowing arbitrary code execution. The module is written in Ruby and leverages Metasploit's TcpServer and SEH exploitation mixins. The payload is customizable (up to 1000 bytes) and avoids specific bad characters. The exploit targets LeapFTP clients running on Windows 2000 (SP0/SP4) and Windows XP (SP0). The only network endpoint is the attacker's FTP server, which listens on TCP port 21. The repository is operational and provides a working exploit for the specified vulnerability.
