CVE-2024-4044

Code execution via unvalidated project-file deserialization

Published May 10, 2024 · Updated Aug 1, 2024

Deserialization in NI FlexLogger and InstrumentStudio 2024 Q1 and earlier allows remote attackers to execute code via a crafted project file. The shared project-file parser accepts user-supplied content without sufficient validation and deserializes it inside the application process. A user must open the malicious project file; successful exploitation runs arbitrary code in the affected application's process context.
