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. For a list of modified CVSS scores, please see the official Bosch Advisory Appendix chapter Modified CVSS Scores for CVE-2021-23859
