MajorDoMo (Major Domestic Module) before commit 0662e5e contains an unauthenticated command execution vulnerability in thumb.php. According to the provided content, the issue is triggered via shell metacharacters supplied to thumb.php, indicating insufficient neutralization of attacker-controlled input before it is incorporated into an OS command. This allows remote attackers to inject shell syntax and execute arbitrary commands in the context of the web application. The content explicitly notes that this CVE is unrelated to the Majordomo mailing-list manager.

This repository contains a single Metasploit module targeting a command injection vulnerability (CVE-2023-50917) in MajorDoMo home automation software (versions before commit 0662e5e). The exploit leverages a vulnerable GET parameter ('transport') in the /modules/thumb/thumb.php endpoint to inject and execute arbitrary shell commands on the target system. The module includes a check method to verify the presence of MajorDoMo by requesting /favicon.ico and checking its MD5 hash, and then tests for the vulnerability by timing a sleep command. The exploit is operational, allowing remote command execution as the web server user. The code is written in Ruby and structured as a standard Metasploit exploit module.
This repository provides a working exploit for CVE-2023-50917, a critical unauthenticated remote code execution (RCE) vulnerability in MajorDoMo's thumb.php module. The exploit consists of a Python script (exploit.py) that interacts with the vulnerable endpoint '/modules/thumb/thumb.php' on a target MajorDoMo instance. The script provides an interactive shell-like interface, allowing the attacker to send arbitrary system commands to the target server via the 'transport' parameter, which is vulnerable to command injection due to lack of input sanitization. The exploit leverages a base64-encoded 'url' parameter to bypass initial validation and injects commands using a crafted 'transport' value. The output of the executed command is extracted from the HTTP response and displayed to the attacker. The repository also includes a README.md with a detailed technical write-up and a requirements.txt listing Python dependencies. The exploit is operational and can be used to gain remote shell access to unpatched MajorDoMo installations.
