CVE-2021-23862
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA 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).
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceAuthenticated administrative users can send specially crafted configuration packets that enable execution of arbitrary commands with system-level privileges. This command injection vulnerability affects VRM, DIVAR IP, BVMS with VRM installed, and VIDEOJET decoders (VJD-7513 and VJD-8000).

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed Bosch video security productCheck Windows Programs and Features or system documentation for presence of BVMS, VRM, DIVAR IP, or Videojet Decoder softwareAffected if Any of these products are installed
-
Determine BVMS versionOpen BVMS Configuration Client, go to System > About, or check the version in Windows Programs and Features under 'Bosch Video Management System'Affected if Version is <= 9.0, or >= 10.0 and < 10.0.2, or = 10.1, or = 11.0
-
Determine VRM versionOpen BVMS Configuration Client and check VRM version under Devices > VRM, or check Windows Programs and Features for 'Bosch Video Recording Manager' versionAffected if Version is <= 3.81, or >= 3.82 and <= 3.82.0057, or >= 3.83 and <= 3.83.0021, or >= 4.0 and <= 4.00.0070
-
Determine Videojet Decoder firmware versionAccess the decoder web interface and check the firmware version under System > Information, or use the decoder's serial number label and consult device documentationAffected if Videojet Decoder 7513 firmware is <= 10.22.0038, or Videojet Decoder 8000 firmware is <= 10.01.0036
-
Assess administrative access exposureReview network configuration to determine if the BVMS/VRM management interfaces or decoder admin web portals are accessible from untrusted networksAffected if Administrative interfaces are exposed to network segments that include untrusted users, enabling authenticated attackers to send malicious configuration packets
The environment is affected if any Bosch video product (BVMS, VRM, DIVAR IP, or Videojet Decoder) is running an affected version AND administrative interfaces are accessible to potential attackers.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor data10.0.2
Restrict administrative access to trusted personnel only, implement network segmentation to limit exposure, and apply vendor patches when released. Monitor configuration change logs for suspicious administrative activity.
