CVE-2024-3467

There is a vulnerability in AVEVA PI Asset Framework Client that could allow malicious code to execute on the PI System Explorer environment under the privileges of an interactive user that was socially engineered to import XML supplied by an attacker.

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.
