List of CVEs: CVE-2020-28653, CVE-2021-3287
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 Ranking and Traits
Module Ranking:
- excellent: The exploit will never crash the service. This is the case for SQL Injection, CMD execution, RFI, LFI, etc. No typical memory corruption exploits should be given this ranking unless there are extraordinary circumstances. More information about ranking can be found here.
Reliability:
- repeatable-session: The module is expected to get a shell every time it runs.
Stability:
- crash-safe: Module should not crash the service.
Side Effects:
- artifacts-on-disk: Modules leaves a payload or a dropper on the target machine.

Vulnerable Application
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.
CVE-2020-28653
This vulnerability affects OpManager versions 12.1 - 12.5.232. The vulnerability involves sending a malicious PDU to the SmartUpdateManager handler that when deserialized executes an arbitary OS command.
CVE-2021-3287
This vulnerability is a patch bypass for CVE-2020-28653 and affects OpManager versions 12.5.233 - 12.5.328. When the
original vulnerability was patched, it was done so using a new ITOMObjectInputStream deserializer class. This object
has a flaw in its validation logic. The object works by requiring the caller to specify a list of one or more object
classes that can be deserialized. If an instance is used to perform more than one readObject call however, only the
first is protected because once a serialized object of an allowed type is read from the stream, the
ITOMObjectInputStream instance remains in a sort of authenticated state where subsequent objects can be read of any
type.
The exploit technique for this CVE leverages this by first sending a legitimate, serialized SUMPDU to create an instance
of the SUMServerIOAndDataAnalyzer object whose process method makes multiple readObject calls using the same
instance for each.
Unlike exploiting CVE-2020-28653, to exploit CVE-2021-3287 the target server must have the SUM server running. This is not the case for the standard installer, but is the case for "Central" variant. Without the SUM server running, the log handler is not initialized which causes the request handler to crash making the vulnerable code path inaccessible.
Setup (Windows)
- Download an affected version for either Windows or Linux from the archive
- Run the installer executable
- Accept the default values for all settings (skip registration), until the very end when prompted to start the application
- Unselect the option to start the application
- If this option is missed, just navigate to the tray icon where it will say that it's starting and select the option to stop it
- Start a command prompt as an administrative user
- Navigate to
C:\Program Files\ManageEngine\OpManager\bin, older versions useC:\ManageEngine\OpManager\bin - Run
run.bat - View and accept the license terms
- Press
fto run the product in Free mode
OpManager should start successfully after a few minutes. At that point the service can be exploited. In this case the
session will be opened in the context of the user that ran the service with run.bat. Once the server is restarted and
OpManager starts automatically, the vulnerability can be exploited to open a session in the context of NT
AUTHORITY\SYSTEM.
Setup (Linux)
- Download an affected version for either Windows or Linux from the archive
- Run the installer executable as root
- Accept the default values for all settings (skip registration)
- Navigate to
/opt/ManageEngine/OpManagerCentral/bin, older versions use/opt/ManageEngine/OpManager/bin - Run
run.shas root
Verification Steps
- Install the application
- Start msfconsole
- Do:
use exploit/multi/http/opmanager_sumpdu_deserialization - Set the
RHOSTS,TARGET,PAYLOADand payload-related options as necessary - Do:
run - You should get a shell.
