ManageEngine OpManager SumPDU Java Deserialization
Description
An HTTP endpoint used by the Manage Engine OpManager Smart Update Manager component can be leveraged to deserialize an arbitrary Java object. This can be abused by an unauthenticated remote attacker to execute OS commands in the context of the OpManager application (NT AUTHORITY\SYSTEM on Windows or root on Linux). This vulnerability is also present in other products that are built on top of the OpManager application. This vulnerability affects OpManager versions 12.1 - 12.5.328. Automatic CVE selection only works for newer targets when the build number is present in the logon page. Due to issues with the serialized payload this module is incompatible with versions prior to 12.3.238 despite them technically being vulnerable.

- Collect and share all the information you need to conduct a successful and efficient penetration test
- Simulate complex attacks against your systems and users
- Test your defenses to make sure they’re ready
- Automate Every Step of Your Penetration Test
Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
