CVE-2024-12741

A deserialization of untrusted data vulnerability exists in NI DAQExpress that may result in remote code execution. Successful exploitation requires an attacker to get a user to open a specially crafted project file. This vulnerability affects DAQExpress 5.1 and prior versions.  Please note that DAQExpress is an EOL product and will not receive any updates.

Weakness

The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.

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.
