Solution and Mitigations****Software Updates

The recommended approach is to update the affected Bosch software to a fixed version. If an update is not possible in timely manner, users are recommended to follow the mitigation described in the following section.

Firewalling

For CVE-2021-23859 disallowing connections to Port 40080 - 40099 TCP to the software / appliance by means of a firewall prevents the attacker from accessing the vulnerable interface. If protected by a firewall the attack is limited to local signed-in users.

Vulnerability Details****CVE-2021-23859

CVE description: An unauthenticated attacker is able to send a special HTTP request, that causes a service to crash.

In case of a standalone VRM or BVMS with VRM installation this crash also opens the possibility to send further unauthenticated commands to the service.

On some products the interface is only local accessible lowering the CVSS base score.
