CVE-2024-6794

A deserialization of untrusted data vulnerability exists in NI VeriStand Waveform Streaming Server that may result in remote code execution. Successful exploitation requires an attacker to send a specially crafted message. These vulnerabilities affect NI VeriStand 2024 Q2 and prior versions.

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.
