CVE-2022-32521

A CWE 502: Deserialization of Untrusted Data vulnerability exists that could allow code to be remotely executed on the server when unsafely deserialized data is posted to the web server. Affected Products: Data Center Expert (Versions prior to V7.9.0)

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.
