ManageEngine OpManager SumPDU Java Deserialization



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.

Module Options

To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':

msf > use exploit/multi/http/opmanager_sumpdu_deserialization
msf exploit(opmanager_sumpdu_deserialization) > show targets
msf exploit(opmanager_sumpdu_deserialization) > set TARGET < target-id >
msf exploit(opmanager_sumpdu_deserialization) > show options
    ...show and set options...
msf exploit(opmanager_sumpdu_deserialization) > exploit

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.
