Loading vulnerability…
GuildFTPd 0.999.14 is vulnerable to a heap corruption issue when handling long arguments to the CWD and LIST FTP commands. The vulnerability arises from improper memory management, specifically an improper free call, which can lead to heap-based buffer overflows. This flaw may allow remote attackers to crash the service or potentially execute arbitrary code.

This repository contains a single Metasploit auxiliary module targeting a denial-of-service (DoS) vulnerability in Guild FTPd versions 0.999.8.11 and 0.999.14 on Windows (CVE-2008-4572). The exploit requires valid FTP credentials to log in to the target server. Once authenticated, it sends a specially crafted CWD command (with a long path) followed by a LIST command with a long argument, which triggers a heap corruption and crashes the FTP service. The module is written in Ruby and leverages Metasploit's FTP and DoS auxiliary components. The only file present is the exploit module itself, and it is structured as a typical Metasploit auxiliary module with options for FTP username and password. The attack vector is network-based, targeting the FTP service (port 21/tcp) on the vulnerable server.
