Credential disclosure via weak password hashing
Published May 19, 2022 · Updated Apr 16, 2025
Weak password protection in Bachmann M-Base Controllers running MSYS 1.06.14 and later allows remote attackers to obtain password hashes. The built-in authentication handler protects device passwords with hashing that requires insufficient computational effort, enabling offline password recovery. Default Security Level 0 exposes hashes without authentication; Level 4 requires authenticated remote or unauthenticated physical access.

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.
