CVE-2020-6770 — Bosch Bosch Video Management System Mobile Video Service security vulnerability

Critical CVSS 10

Deserialization of Untrusted Data in the BVMS Mobile Video Service (BVMS MVS) allows an unauthenticated remote attacker to execute arbitrary code on the system. This affects Bosch BVMS versions 10.0 <= 10.0.0.1225, 9.0 <= 9.0.0.827, 8.0 <= 8.0.0.329 and 7.5 and older. This affects Bosch DIVAR IP 3000 and DIVAR IP 7000 if a vulnerable BVMS version is installed.

Unsafe deserialization and object reconstruction

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

Check exposure

  • Inventory serialization formats accepted from requests, queues, caches, files, cookies, and cross-service messages.
  • Trace whether untrusted input can select classes, types, callbacks, constructors, or object hooks during decoding.
  • Identify signing, schema validation, trust-boundary, and compatibility settings for each decoder.

Remediate safely

  • Replace native object deserialization with a data-only format and explicit schema validation.
  • If replacement is not immediate, use a safe decoder with a minimal type allowlist and disable polymorphic or executable hooks.
  • Update the affected library and add inert tests for unknown types, extra fields, malformed nesting, and unsigned data.
