An improper handling of a malformed API answer packets to API clients in Bosch BT software products can allow an unauthenticated attacker to cause a Denial of Service (DoS) situation. To exploit this vulnerability an attacker has to replace an existing API server e.g. through Man-in-the-Middle attacks.

Information Disclosure in Operator Client application in BVMS 10.1.1, 11.0 and 11.1.0 and VIDEOJET Decoder VJD-7513 versions 10.23 and 10.30 allows man-in-the-middle attacker to compromise confidential video stream. This is only applicable for UDP encryption when target system contains cameras with platform CPP13 or CPP14 and firmware version 8.x.

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.

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.

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.
