CVE-2010-20103 refers to a supply-chain compromise of the official ProFTPD 1.3.3c source tarball distributed between 2010-11-28 and 2010-12-02. A malicious backdoor was inserted into the released source package rather than arising from an inadvertent programming flaw in the upstream codebase. The implanted backdoor added a hidden FTP command trigger; when a specially crafted command was sent to a server built from the trojanized 1.3.3c source, the server executed arbitrary shell commands on the underlying operating system. Because ProFTPD commonly runs with elevated privileges, the injected functionality could execute commands as root. The issue therefore enabled remote, unauthenticated command execution against affected FTP servers compiled and deployed from the compromised tarball.

This repository contains a single Metasploit module targeting the ProFTPD 1.3.3c backdoor (CVE-2010-20103). The exploit leverages a malicious backdoor present in certain compromised ProFTPD 1.3.3c archives distributed between November 28th and December 2nd, 2010. The module connects to a target FTP server and sends the special command 'HELP ACIDBITCHEZ' to trigger the backdoor. If the server is vulnerable, it allows the attacker to execute arbitrary shell commands on the target system. The payload is customizable and can be any shell command, such as spawning a reverse shell. The exploit is operational and requires the target to be running the specific backdoored version of ProFTPD. The only fingerprintable endpoint is the unique backdoor trigger string 'HELP ACIDBITCHEZ'. The code is written in Ruby and is structured as a standard Metasploit exploit module.
