Missing Authentication for Critical Function in the Bosch Video Streaming Gateway (VSG) allows an unauthenticated remote attacker to retrieve and set arbitrary configuration data of the Video Streaming Gateway. A successful attack can impact the confidentiality and availability of live and recorded video data of all cameras configured to be controlled by the VSG as well as the recording storage associated with the VSG. This affects Bosch Video Streaming Gateway versions 6.45 <= 6.45.08, 6.44 <= 6.44.022, 6.43 <= 6.43.0023 and 6.42.10 and older. This affects Bosch DIVAR IP 3000, DIVAR IP 7000 and DIVAR IP all-in-one 5000 if a vulnerable VSG version is installed with BVMS. This affects Bosch DIVAR IP 2000 <= 3.62.0019 and DIVAR IP 5000 <= 3.80.0039 if the corresponding port 8023 has been opened in the device's firewall.

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

An error in a page handler of the VRM may lead to a reflected cross site scripting (XSS) in the web-based interface. To exploit this vulnerability an attack must be able to modify the HTTP header that is sent. This issue also affects installations of the DIVAR IP and BVMS with VRM installed.

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).
