Loading vulnerability…
A stack-based buffer overflow exists in the implementation of the 'site chmod' command in Serv-U FTP Server versions prior to 4.2. The vulnerability is triggered when a remote attacker supplies an overly long filename as an argument to the 'site chmod' command, resulting in a buffer overflow on the stack. This can allow for the execution of arbitrary code with the privileges of the Serv-U process.

This repository contains a single Metasploit module (Ruby file) that exploits a stack buffer overflow vulnerability in the SITE CHMOD command of Serv-U FTP Server versions prior to 4.2 (CVE-2004-2111). The exploit targets Windows 2000 (SP0-4 EN) and Windows XP (SP0-1 EN) platforms. To use the exploit, valid FTP credentials are required. The module uses an egghunter technique to deliver a customizable payload, which can result in arbitrary code execution on the target system. After exploitation, the FTP service becomes non-functional. The main attack vector is network-based, targeting the FTP service via the SITE CHMOD command. The code is operational and leverages Metasploit's payload system for flexibility.
