Full technical detail▾

Overview

Hirschmann HiLCOS devices OpenBAT, WLC, BAT300, BAT54 prior to 8.80 and OpenBAT prior to 9.10 are shipped with identical default SSH and SSL keys that cannot be changed, allowing unauthenticated remote attackers to decrypt or intercept encrypted management communications. Attackers can perform man-in-the-middle attacks, impersonate devices, and expose sensitive information by leveraging the shared default cryptographic keys across multiple devices.
