CVE-2023-35867 — Bosch Building Integration System Video Engine security vulnerability

Medium CVSS 5.9

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.

Matched remediation archetype

Resource exhaustion and denial of service

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

Check exposure

  • Identify attacker-influenced work factors including input size, nesting, compression, fan-out, regex cost, allocation, recursion, retries, and connection lifetime.
  • Map per-request and shared CPU, memory, disk, descriptor, thread, queue, and downstream-service limits.
  • Determine whether authentication, tenancy, quotas, and rate controls apply before expensive processing begins.

Remediate safely

  • Bound input size, nesting, expansion, work, concurrency, queue depth, retries, and execution time before resource-intensive processing.
  • Release resources on every success, error, cancellation, and timeout path and use backpressure instead of unbounded buffering.
  • Update affected components and add small deterministic tests that assert resource ceilings rather than exhausting a host.
