Deeper analysis
A deserialization of untrusted data vulnerability, tracked as CVE-2024-4044 and assigned CWE-502, exists in common code shared by NI FlexLogger and NI InstrumentStudio. The flaw affects FlexLogger 2024 Q1 and earlier releases along with InstrumentStudio 2024 Q1 and earlier releases, and carries a CVSS 3.1 base score of 7.8 reflecting local attack vector, low attack complexity, and high impact on confidentiality, integrity, and availability.
An attacker can exploit the issue by persuading a user to open a specially crafted project file, resulting in remote code execution on the victim system. The attack requires the victim to possess local access and to interact with the malicious file, after which the attacker obtains full control over the affected application and host.
Advisories published by NI at https://ni.com/r/CVE-2024-4044 address the vulnerability and are the authoritative source for mitigation guidance and any available patches or workarounds.
The EPSS score for this CVE rose from a low baseline to a peak of 0.2007 before settling at the current value of 0.1510, indicating that exploitation interest increased after public disclosure.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Penetration testing supplies malicious serialized objects, detecting unsafe deserialization and supporting corrective actions.
Evaluation of untrusted data handling (deserialization testing) reveals unsafe processing, which the required remediation process addresses.
Untrusted serialized data can be deserialized and observed inside the chamber, blocking gadget-chain exploitation outside the sandbox.
Validates or rejects untrusted serialized data before deserialization occurs.
Identifies and blocks malicious code introduced through deserialization of untrusted data at system boundaries.
Integrity verification of serialized information can detect tampering before deserialization occurs.
Provenance of associated data allows detection of untrusted sources before deserialization or processing occurs.
