CVE-2023-20888

Aria Operations for Networks contains an authenticated deserialization vulnerability. A malicious actor with network access to VMware Aria Operations for Networks and valid member role credentials may be able to perform a deserialization attack resulting in remote code execution.

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.
