CVE-2021-44077 is a critical unauthenticated remote code execution vulnerability affecting Zoho ManageEngine ServiceDesk Plus before 11306, ServiceDesk Plus MSP before 10530, and SupportCenter Plus before 11014. The flaw is associated with handling of /RestAPI endpoints in a servlet and the ImportTechnicians action in the Struts configuration. Available reporting indicates exploitation can be performed with two unauthenticated remote requests: one request uploads an attacker-controlled executable through the exposed REST API path, and a second request causes the server to execute that uploaded payload. The issue therefore allows code execution in the context of the vulnerable application without prior authentication.

This repository contains a single Metasploit module targeting CVE-2021-44077, an unauthenticated remote code execution vulnerability in ManageEngine ServiceDesk Plus (up to build 11305). The exploit works by first checking for the presence of a vulnerable endpoint (/RestAPI/ImportTechnicians), then uploading a malicious Windows executable (msiexec.exe) via a POST request, and finally triggering its execution through another endpoint (/RestAPI/s247action). The payload is generated by Metasploit and typically provides a reverse shell or similar access as SYSTEM. The module is operational and provides full remote code execution if the target is vulnerable. The code is written in Ruby and is structured as a standard Metasploit exploit module, with clear separation of check, exploit, upload, and execution logic. No hardcoded IPs or domains are present; the exploit is configurable for the target's base path and port.
This repository provides a working exploit for CVE-2021-44077, a pre-authentication remote code execution vulnerability in ManageEngine ServiceDesk Plus versions prior to build 11306. The exploit is implemented in a single Python script ('exploit.py') that takes two arguments: the base URL of the target ServiceDesk Plus instance and the path to a Windows executable payload. The script uploads the payload to a specific REST API endpoint and then triggers its execution via another endpoint, resulting in arbitrary code execution on the target server. The README provides detailed usage instructions, including how to generate a payload (e.g., with msfvenom) and how to set up a listener for a reverse shell. The exploit requires the 'requests' Python library and is operational, allowing attackers to run arbitrary code on vulnerable systems. No detection or scanning functionality is present; the script is solely for exploitation. The repository is well-structured, with clear documentation and a single exploit script as the main code file.
