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 · unedited
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.

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 confidence

An authenticated administrative user on the VRM (Video Recording Manager) can execute a special command to gain access to extended debug functionality. This debug access allows modification of integrity or availability of installed software. The vulnerability affects DIVAR IP and BVMS systems with VRM installed.

MitigationRestrict administrative access to trusted personnel only and apply vendor-provided patches for VRM when available. Monitor for unauthorized use of debug commands.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Check if VRM is installed
    Look for the Video Recording Manager service or component on the system. On Windows, check for 'VRM' in installed programs via Control Panel or registry. On Linux, check for VRM processes or installation directories.
    Affected if VRM is not installed on the system, then the system is not affected.
  2. Determine VRM version
    Open the BVMS or VRM administration interface and navigate to the 'About' or 'System Info' section to view the installed VRM version. Alternatively, check the program's version information in the installation directory.
    Affected if The installed VRM version falls within any of these ranges: <= 3.81, 3.82 to 3.82.0057, 3.83 to 3.83.0021, or 4.0 to 4.00.0070.
  3. Determine BVMS version if VRM is part of BVMS
    If VRM is installed as part of Bosch Video Management System, check the BVMS version in the same 'About' or 'System Info' section of the management interface.
    Affected if The installed BVMS version is <= 9.0, 10.0 to < 10.0.2, 10.1, or 11.0.
  4. Verify administrative access to VRM
    Check whether any user accounts with administrative privileges exist on the VRM management interface. Review user accounts and their assigned roles in the 'Users' or 'Accounts' section.
    Affected if Administrative user accounts are present and accessible, enabling an authenticated attacker to potentially execute the debug command.

The system is affected if VRM (or BVMS with VRM) is installed with a version matching the affected ranges and administrative access to the VRM management interface exists.

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.

dbcve · scoped
Upgrade available Upgrade to 10.0.2 or later
Fixed in 10.0.2
Interim mitigation

Restrict administrative access to trusted personnel only and apply vendor-provided patches for VRM when available. Monitor for unauthorized use of debug commands.

Recommended fix Moderate confidence

BVMS: 10.0.2+, 10.2+, or 11.0.1+ | VRM: 3.82.0058+, 3.83.0022+, 4.00.0071+, or latest 4.x

  1. For Bosch Video Management System (BVMS): Upgrade to version 10.0.2 or higher, or upgrade to version 10.2 or higher, or upgrade to version 11.0.1 or higher
  2. For Video Recording Manager (VRM): If using VRM 3.82.x, upgrade to version 3.82.0058 or higher
  3. For Video Recording Manager (VRM): If using VRM 3.83.x, upgrade to version 3.83.0022 or higher
  4. For Video Recording Manager (VRM): If using VRM 4.0.x, upgrade to version 4.00.0071 or higher
  5. For Video Recording Manager (VRM): If using VRM versions 3.81 or earlier, upgrade to the latest VRM 4.x version
  6. Apply the upgrade through the Bosch update channels or contact Bosch support for patch files
  7. After upgrade, verify the debug functionality is no longer accessible to administrative users
