ZOHO ManageEngine OpManager 11.5 build 11600 and earlier contains a vulnerability where the IntegrationUser account is configured with a hardcoded password ('plugin'). This allows any remote authenticated user who knows this password to gain administrator access to the application.

This repository contains a single Metasploit module targeting ManageEngine OpManager (versions 11.0 and 11.4-11.6) on Windows. The exploit leverages two vulnerabilities: a default hidden administrator account ('IntegrationUser' with password 'plugin') and an SQL query abuse that allows arbitrary file writes. The module authenticates using the default credentials, retrieves an API key, and abuses the SQL query interface to write a malicious WAR file (containing a Java payload) to the Tomcat webapps directory. The payload is then triggered via HTTP, resulting in remote code execution on the server. The module is operational and provides a shell or Meterpreter session to the attacker. The main attack vector is network-based, targeting the OpManager web interface. The code is structured as a typical Metasploit exploit module, with clear separation of version checking, authentication, SQL abuse, payload deployment, and cleanup routines.
