Loading vulnerability…
A stack-based buffer overflow exists in freeFTPd versions prior to 1.0.9 when logging is enabled. The vulnerability is triggered by sending an overly long USER command to the FTP service, which can overflow a stack buffer and potentially allow remote attackers to crash the application or execute arbitrary code.

This repository contains a single Metasploit module (freeftpd_user.rb) that exploits a stack buffer overflow vulnerability in freeFTPd 1.0 running on Windows systems. The exploit targets the FTP service by sending a specially crafted USER command to overflow the stack and execute arbitrary code. The module supports multiple Windows targets (2000, XP, NT, 2003 Server) and requires that logging is enabled on the freeFTPd service (which is not the default setting). The payload is customizable and can be any Metasploit payload fitting within 800 bytes and avoiding certain bad characters. The exploit is weaponized, as it is part of the Metasploit framework and provides a handler for post-exploitation. The only fingerprintable endpoint is the FTP service (typically port 21) on the target host.
