CVE-2016-5669 — Crestron Dm-Txrx-100-Str Firmware security vulnerability
Critical
CVSS 9.8
Crestron Electronics DM-TXRX-100-STR devices with firmware before 1.3039.00040 use a hardcoded 0xb9eed4d955a59eb3 X.509 certificate from an OpenSSL Test Certification Authority, which makes it easier for remote attackers to conduct man-in-the-middle attacks against HTTPS sessions by leveraging the certificate's trust relationship.

General vulnerability remediation
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Confirm the affected component, deployment paths, reachable interfaces, and enabled features from inventories and configuration, without probing production destructively.
- Compare the advisory's affected conditions with the repository lockfiles, build manifests, artifacts, and runtime inventory.
- Identify data sensitivity, trust boundaries, and privilege level for every confirmed affected deployment.
Remediate safely
- Apply a vendor-supported fix or remove the affected component or feature; record the selected change and its source in the repository.
- Update direct and transitive dependency locks, generated artifacts, deployment manifests, and asset inventories together.
- Add a regression test for the documented unsafe condition using inert inputs and preserve rollback instructions.
