Remote decryption via weak SSH ciphers
Published Dec 13, 2022 · Updated Apr 21, 2025
Use of a Broken or Risky Cryptographic Algorithm in SICK AG RFU62x Firmware before 2.21 allows remote authenticated users to decrypt encrypted data via SSH. The SSH interface permits a low-privileged user to request weak cipher suites, causing protected traffic to be encrypted with algorithms that can be decrypted. Exploitation requires valid low-privilege SSH access and the weak-suite option; the documented impact is confidentiality loss without integrity or availability effects.

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.
