CVE-2022-38650

A remote unauthenticated insecure deserialization vulnerability exists in VMware Hyperic Server 5.8.6. Exploitation of this vulnerability enables a malicious party to run arbitrary code or malware within Hyperic Server and the host operating system with the privileges of the Hyperic server process. NOTE: This vulnerability only affects products that are no longer supported by the maintainer.

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.
