Loading vulnerability…
A privilege escalation vulnerability exists in OpenNMS Horizon 31.0.8 and earlier, and Meridian versions prior to 2023.1.5, where users with the ROLE_FILESYSTEM_EDITOR permission can escalate their privileges to ROLE_ADMIN or any other role. This allows an attacker with filesystem editor access to gain administrative control over the application.

This repository contains a single Metasploit module targeting OpenNMS Horizon (Linux) for authenticated remote code execution (RCE). The exploit leverages built-in functionality and, for versions <=32.0.1, can escalate privileges using CVE-2023-40315 or CVE-2023-0872. The module requires valid credentials for a user with specific roles and interacts with the OpenNMS web application via HTTP(S), manipulating configuration files and REST API endpoints to achieve code execution as the 'opennms' user. The default payload is a Meterpreter reverse shell, but the module supports any command payload. The exploit is weaponized, allowing for customizable payloads and automated cleanup. Key endpoints include the OpenNMS base path, REST API endpoints, and several XML configuration files. The code is written in Ruby and is structured as a standard Metasploit exploit module.
