CVE intelligence and bounded remediation
CVE-2019-18833 — Barco ClickShare Button R9861500D01 devices before 1.9.0 allow Information exposure (issue 2 of 2)
Barco ClickShare Button R9861500D01 devices before 1.9.0 allow Information exposure (issue 2 of 2).. The encryption key of the media content which is shared between a ClickShare Button and a ClickShare Base Unit is randomly generated for each new session and communicated over a TLS connection. An attacker who is able to perform a Man-in-the-Middle attack between the TLS connection, is able to obtain the encryption key.

Matched remediation archetype
Cryptography, certificate, signature, and channel validation
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Inventory affected algorithms, key uses, trust stores, certificate validation settings, random sources, and plaintext channels across clients and services.
- Determine which secrets, identities, signatures, or data protections depend on the affected primitive or validation path.
- Check debug, compatibility, fallback, and hostname or audience override settings in build and runtime configuration.
Remediate safely
- Use a maintained platform cryptographic API with approved algorithms, modes, parameters, randomness, and full peer identity validation.
- Remove insecure fallback and validation bypasses; separate keys by purpose and load them from managed secret storage.
- Plan rotation or reissuance for affected keys, certificates, tokens, hashes, or ciphertext and document compatibility sequencing.
