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

A crafted configuration packet sent by an authenticated administrative user can be used to execute arbitrary commands in system context. This issue also affects installations of the VRM, DIVAR IP, BVMS with VRM installed, the VIDEOJET decoder (VJD-7513 and VJD-8000).

By executing a special command, an user with administrative rights can get access to extended debug functionality on the VRM allowing an impact on integrity or availability of the installed software. This issue also affects installations of the DIVAR IP and BVMS with VRM installed.

A recently discovered security vulnerability affects all Bosch Video Management System (BVMS) versions 9.0 and below, DIVAR IP 2000, 3000, 5000 and 7000, Video Recording Manager (VRM), Video Streaming Gateway (VSG), Configuration Manager, Building Integration System (BIS) with Video Engine, Access Professional Edition (APE), Access Easy Controller (AEC), Bosch Video Client (BVC) and Video SDK (VSDK).
