Am I affected?
Debian, Ubuntu or Red Hat sometimes backport a fix without changing the upstream version number: such a version reads « to verify », never « affected ».With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.
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. For a list of modified CVSS scores, please see the official Bosch Advisory Appendix chapter Modified CVSS Scores for CVE-2021-23859
