CVE-2025-54818

Credential theft via cleartext management protocol

Published Sep 18, 2025 · Updated Sep 18, 2025

Cleartext transmission in Cognex In-Sight products 5.x through 6.5.1 allows adjacent attackers to intercept credentials on TCP port 1069. The proprietary management protocol sends registered usernames and passwords without transport encryption during user-management operations. Exploitation requires adjacent network access and passive user interaction; intercepted credentials grant device access and enable management operations.
