CVE-2020-11853 is a critical vulnerability in multiple Micro Focus products, including Operations Bridge Manager (OBM), Universal CMDB, Application Performance Management, Data Center Automation, Hybrid Cloud Management, and Service Management Automation. The vulnerability arises from insecure Java deserialization in numerous endpoints and services, particularly in UCMDB and related components. Attackers can exploit these flaws to achieve remote code execution as root or SYSTEM, either with or without authentication, depending on the endpoint. The use of outdated and insecure Java libraries (such as Apache Commons BeanUtils, BeanShell, and C3P0) further facilitates exploitation by providing known gadget chains. The vulnerability affects both Windows and Linux installations, with some privilege escalation vectors specific to Windows due to incorrect default folder permissions.

This repository contains a single Metasploit module (Ruby) that exploits an authenticated Java deserialization vulnerability (CVE-2020-11853) in Micro Focus Operations Bridge Manager (OBM) and related products. The exploit requires a valid authenticated session (LWSSO_COOKIE_KEY) and targets specific HTTP(S) endpoints on the OBM server. Upon successful exploitation, it achieves remote code execution as a privileged user (root/SYSTEM) by leveraging a C3P0 gadget generated with ysoserial and delivering a Java Meterpreter reverse shell payload. The module is weaponized, allowing for customizable payloads and is suitable for post-authentication exploitation scenarios. The code is structured as a standard Metasploit module, with clear separation of initialization, checking, and exploitation logic. The main endpoints targeted are '/legacy/topaz/sitescope/conf/registration' and '/legacy/topaz/sitescope/conf/download'.
This repository contains a single Metasploit module (Ruby file) that exploits two chained vulnerabilities (CVE-2020-11853 and CVE-2020-11854) in Micro Focus UCMDB (part of Operations Bridge Manager) versions 2020.05 and below. The exploit first authenticates using a hardcoded 'diagnostics' user, then leverages a Java deserialization vulnerability to achieve unauthenticated remote code execution. The module supports both Windows and Linux targets, delivering a reverse shell payload (Meterpreter for Windows, Python for Linux). The attack is performed over HTTPS (default port 8443), targeting various UCMDB service endpoints. The code is weaponized, allowing for easy payload customization and integration into the Metasploit framework. The repository is structured as a single Ruby file compatible with Metasploit, and all logic is contained within this file.
