No fix is confirmed yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for the fix.

The SSH service on BSH ELP (Electronic Platform) modules contains a platform-specific vulnerability due to an improperly secured default configuration. An insecure, non-revocable SSH public key is included in the firmware's authorized_keys file for the root user. An attacker in possession of the corresponding private key could leverage it to bypass authentication and gain root-level access to the appliance.

Exploitation none (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact total (CISA Vulnrichment). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
