CVE-2019-11684 — Bosch Video Recording Manager security vulnerability

Critical CVSS 9.9

Improper Access Control in the RCP+ server of the Bosch Video Recording Manager (VRM) component allows arbitrary and unauthenticated access to a limited subset of certificates, stored in the underlying Microsoft Windows operating system. The fixed versions implement modified authentication checks. Prior releases of VRM software version 3.70 are considered unaffected. This vulnerability affects VRM v3.70.x, v3.71 < v3.71.0034 and v3.81 < 3.81.0050; DIVAR IP 5000 3.80 < 3.80.0039; BVMS all versions using VRM.

Matched remediation archetype

Authentication bypass and missing authentication

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map every affected endpoint and protocol path, including alternate ports, legacy routes, recovery flows, service accounts, and machine-to-machine access.
  • Confirm which deployments enable the affected authentication mode and whether the interface is reachable from untrusted networks.
  • Review session, token, credential, and proxy trust configuration without attempting account takeover.

Remediate safely

  • Apply the supported fix and centralize fail-closed authentication before protected request handling.
  • Remove default or embedded credentials, rotate affected secrets and sessions, and bind authentication decisions to the intended audience and channel.
  • Add negative tests for alternate routes, malformed or absent credentials, recovery flows, and proxy-derived identity.
