CVE-2021-29656
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedPexip Infinity Connect before 1.8.0 mishandles TLS certificate validation. The allow list is not properly checked.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidencePexip Infinity Connect versions prior to 1.8.0 fail to properly validate TLS certificates by not correctly checking the certificate allow list, which could enable connections to unauthorized or malicious servers due to improper trust validation.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check installed Pexip Infinity Connect versionOpen the Pexip Infinity Connect application and navigate to Help > About, or check the installed package version through your system's software management toolAffected if The displayed version is earlier than 1.8.0
-
Verify client usage contextDetermine whether the client is used to connect to remote Pexip conferencing nodes, as TLS certificate validation occurs during server connectionsAffected if The client is used to connect to remote Pexip servers and the version is below 1.8.0
-
Review connection logs for certificate validationExamine Pexip Infinity Connect connection logs for any TLS handshake or certificate validation errors or warnings related to server connectionsAffected if The version is below 1.8.0 and connections to external servers are being established
You are affected if Pexip Infinity Connect version is below 1.8.0 and the client is used to connect to remote Pexip conferencing servers over TLS.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped1.8.0
Upgrade Pexip Infinity Connect to version 1.8.0 or later to remediate the TLS certificate validation bypass.
Pexip Infinity Connect 1.8.0 or later
- 1. Identify all deployed instances of Pexip Infinity Connect in your environment
- 2. Check the current version of each Infinity Connect installation
- 3. For any instance running a version prior to 1.8.0, obtain the version 1.8.0 or later from the official Pexip distribution channels
- 4. Follow the standard Pexip upgrade procedure for Infinity Connect clients
- 5. After upgrade, verify that TLS certificate validation is functioning correctly
- 6. Confirm the version has been updated to 1.8.0 or higher
