Descriptions

A deserialization of untrusted data vulnerability exists in common code used by FlexLogger and InstrumentStudio 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 NI FlexLogger 2024 Q1 and prior versions as well as NI InstrumentStudio 2024 Q1 and prior versions.

Existe una vulnerabilidad de deserialización de datos no confiables en el código común utilizado por FlexLogger e InstrumentStudio que puede resultar en la ejecución remota de código. La explotación exitosa requiere que un atacante consiga que un usuario abra un archivo de proyecto especialmente manipulado. Esta vulnerabilidad afecta a NI FlexLogger 2024 Q1 y versiones anteriores, así como a NI InstrumentStudio 2024 Q1 y versiones anteriores.

This vulnerability allows remote attackers to execute arbitrary code on affected installations of NI FlexLogger. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the parsing of FLXPROJ files. The issue results from the lack of proper validation of user-supplied data, which can result in deserialization of untrusted data. An attacker can leverage this vulnerability to execute code in the context of the current process.
