CVE-2025-7970Network attack vector

Traffic decryption via flawed authentication cryptography

Published Sep 9, 2025 · Updated Sep 9, 2025

Incorrect authentication cryptography in Rockwell Automation FactoryTalk Activation Manager 5.00 through 5.01 allows remote attackers to decrypt traffic. Rockwell Automation has not disclosed the affected protocol, algorithm, code locus, or specific cryptographic operation implemented incorrectly. Unauthenticated network reachability is sufficient, and successful exploitation exposes protected data or permits session hijacking without a reported availability impact.
