CVE-2022-33318

Deserialization of Untrusted Data vulnerability in ICONICS GENESIS64 versions 10.97.1 and prior and Mitsubishi Electric MC Works64 versions 4.04E (10.95.210.01) and prior allows a remote unauthenticated attacker to execute an arbitrary malicious code by sending specially crafted packets to the GENESIS64 server.

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.
