CVE-2024-5016

In WhatsUp Gold versions released before 2023.1.3, Distributed Edition installations can be exploited by using a deserialization tool to achieve a Remote Code Execution as SYSTEM.  The vulnerability exists in the main message processing routines NmDistributed.DistributedServiceBehavior.OnMessage for server and NmDistributed.DistributedClient.OnMessage for clients.

Weakness

The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.

Affected Software

Potential Mitigations

• Make fields transient to protect them from deserialization.
• An attempt to serialize and then deserialize a class containing transient fields will result in NULLs where the transient data should be. This is an excellent way to prevent time, environment-based, or sensitive variables from being carried over and used improperly.
