Summary

The SSH server on SCALANCE devices (all versions < V5.5.2) is configured to offer weak ciphers by default. This could allow an unauthorized attacker in a man-in-the-middle position to read and modify data passed between legitimate clients and the affected device.

Risk Assessment

An attacker could intercept or modify authentication and configuration data transmitted over SSH, potentially leading to confidentiality and integrity breaches.

Recommendation

Update SCALANCE device firmware to version V5.5.2 or later. Until updated, consider disabling weak ciphers in the SSH configuration.
