CVE-2023-31222

Deserialization of untrusted data in Microsoft Messaging Queuing Service in Medtronics Paceart Optima versions 1.11 and earlier on Windows allows an unauthorized user to impact a healthcare delivery organization’s Paceart Optima system cardiac device causing data to be deleted, stolen, or modified, or the Paceart Optima system being used for further network penetration via network connectivity.

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.
