CVE-2020-11858 is a privilege escalation vulnerability in Micro Focus Operations Bridge Manager (OBM) and Operations Bridge (containerized) products. The vulnerability arises from incorrect default folder permissions on Windows installations, where non-administrative users are allowed to write files to the installation directory and its subfolders. This misconfiguration enables local attackers to place malicious files, such as web shells, in sensitive directories (e.g., Tomcat webapps), which are then executed with SYSTEM privileges, resulting in code execution with escalated privileges.

This repository contains a single Metasploit module (Ruby) for exploiting a local privilege escalation vulnerability in Micro Focus Operations Bridge Manager (OBM) <= 2020.05 and Operations Bridge Reporter (OBR) <= 10.40 on Windows. The exploit leverages weak folder permissions, allowing an unprivileged user to drop a malicious JSP file into a web-accessible directory. The module then triggers the JSP via a local web request, resulting in code execution as SYSTEM. The exploit requires a meterpreter session and Powershell on the target. The module is operational, providing a working privilege escalation path, and includes references to CVE-2020-11858 and CVE-2020-11855. Key fingerprintable endpoints include the file paths where the JSP is dropped and the HTTP paths used to trigger the payload. The repository is structured as a single Metasploit exploit module file.
