Deeper analysis
A deserialization of untrusted data vulnerability, tracked as CVE-2024-6794 and assigned CWE-502, affects the Waveform Streaming Server component of NI VeriStand. The flaw permits remote code execution when an attacker supplies a specially crafted message and impacts all versions through 2024 Q2. It carries a CVSS 3.1 base score of 9.8, reflecting network attack vector, low attack complexity, and no required privileges or user interaction.
An unauthenticated remote attacker can send the malicious message directly to the affected server, resulting in arbitrary code execution on the host with full confidentiality, integrity, and availability impact. No local access or authenticated session is needed for successful exploitation.
National Instruments has published an advisory detailing the issue and directing users to available critical and security updates for NI VeriStand. The EPSS score rose from a low baseline to a peak of 0.0796, indicating emerging exploitation interest after disclosure that warrants renewed attention.

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.
