BACnet service disruption via weak configuration permissions
Published Nov 18, 2024 · Updated Aug 27, 2025
Incorrect permissions in WAGO controller firmware allow remote authenticated users to alter BACnet service properties through SSH. The embedded Linux system fails to enforce the administrator-only restriction shown by the web interface, leaving BACnet configuration writable to user-level accounts. User-level SSH access is required, and disabling or changing the service can interrupt BACnet communication without affecting other device functions.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=0.0.0 <=4.5.10 (FW27)
