FileZilla Server before 0.9.22 contains a remotely triggerable denial-of-service flaw in its handling of FTP command arguments. According to the provided vulnerability record, a wildcard argument supplied to the LIST or NLST commands can trigger a NULL pointer dereference and crash the server. The record also notes CVE analysis suggesting the issue might instead be related to a malformed PORT command, so the exact triggering input is not fully certain from the available information. In either case, the vulnerability affects FileZilla Server versions prior to 0.9.22 and results in process termination due to dereferencing a NULL pointer during command processing.

This repository contains a single Metasploit auxiliary module targeting a denial of service (DoS) vulnerability in FileZilla FTP Server versions 0.9.21 and earlier (CVE-2006-6565). The exploit works by sending a malformed PORT command followed by a LIST command to the FTP server, which causes the server to attempt to write to a NULL pointer, resulting in a crash. The module is written in Ruby and leverages Metasploit's FTP and DoS auxiliary components. The only file present is the exploit module itself, which is structured with an initialization method providing metadata and a 'run' method that performs the attack sequence. The attack vector is network-based, requiring access to the FTP service (typically on TCP port 21). No payload is delivered; the exploit's sole purpose is to crash the target service, making it a proof-of-concept (POC) DoS exploit.
