SALT SDK TLS Cert Validation Bypass in COMOS, NX, Simcenter, Tecnomatix
CVE-2025-40801 Published on December 9, 2025
A vulnerability has been identified in COMOS V10.6 (All versions), COMOS V10.6 (All versions), JT Bi-Directional Translator for STEP (All versions), NX V2412 (All versions < V2412.8900 with Cloud Entitlement (bundled as NX X)), NX V2506 (All versions < V2506.6000 with Cloud Entitlement (bundled as NX X)), Simcenter 3D (All versions < V2506.6000 with Cloud Entitlement (bundled as Simcenter X Mechanical)), Simcenter Femap (All versions < V2506.0002 with Cloud Entitlement (bundled as Simcenter X Mechanical)), Simcenter Studio (All versions), Simcenter System Architect (All versions), Tecnomatix Plant Simulation (All versions < V2504.0007). The SALT SDK is missing server certificate validation while establishing TLS connections to the authorization server. This could allow an attacker to perform a man-in-the-middle attack.
Weakness Type
Improper Certificate Validation
The software does not validate, or incorrectly validates, a certificate. When a certificate is invalid or malicious, it might allow an attacker to spoof a trusted entity by interfering in the communication path between the host and client. The software might connect to a malicious host while believing it is a trusted host, or the software might be deceived into accepting spoofed data that appears to originate from a trusted host.
