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 · unedited
Improper certificate validation in Zoom Workplace for Linux before version 6.4.13 may allow an unauthorized user to conduct an information disclosure via network access.

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 confidence

Improper certificate validation in Zoom Workplace for Linux allows an unauthenticated attacker to perform man-in-the-middle attacks by spoofing the server's SSL/TLS certificate. This enables interception of sensitive data transmitted between the client and server due to insufficient certificate chain verification.

MitigationUpgrade Zoom Workplace for Linux to version 6.4.13 or later to obtain the proper certificate validation fix.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Check if Zoom Workplace is installed
    Run: rpm -qa | grep -i zoom OR dpkg -l | grep -i zoom (depending on package manager)
    Affected if No Zoom package found means not applicable to this CVE
  2. Get installed Zoom version
    Run: rpm -qi zoom OR dpkg -s zoom-client (or check /opt/zoom/version.yml)
    Affected if Unable to determine version - cannot confirm status
  3. Compare version to affected range
    Identify the VERSION field from step 2 and compare numerically to 6.4.13
    Affected if Version is below 6.4.13 (e.g., 6.4.10, 6.3.0, etc.)
  4. Verify SSL/TLS is in use
    Confirm Zoom is configured to connect to Zoom servers (default behavior) - check network connections while Zoom is running using: ss -tnp | grep zoom OR lsof -i -P | grep -i zoom
    Affected if Zoom connects to network and transmits data (default behavior)

Environment is affected if Zoom Workplace for Linux is installed with a version lower than 6.4.13 and the client connects to Zoom servers over the network.
