Device takeover via brute-forced weak passwords
Published Jan 30, 2023 · Updated Feb 5, 2025
Weak password requirements in Schneider Electric C-Bus controllers before 1.10.0 allow remote attackers to gain device control by brute force. Schneider Electric identifies a deficient password policy but does not disclose which credential rules or authentication endpoint permit repeated guesses. Network reachability to the controller login service is required, and a successful guess grants control of building-automation 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.
