CVE-2023-39214
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 · uneditedExposure of sensitive information in Zoom Client SDK's before 5.15.5 may allow an authenticated user to enable a denial of service 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 · moderate confidenceThe Zoom Client SDK before version 5.15.5 contains a vulnerability that allows an authenticated user to cause denial of service via network access. The issue involves exposure of sensitive information that can be exploited to trigger the DoS condition.

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.
-
Identify Zoom Client SDK usageSearch your application codebase, dependencies, or build artifacts for the Zoom Meeting SDK (sometimes listed as zoom-sdk or meeting-sdk). Check package.json, pom.xml, requirements.txt, or similar dependency files for zoom-related packages and note the version number found.Affected if The SDK version listed is below 5.15.5 or no version is specified (implying an older release).
-
Check Zoom Meeting Software versionOpen the Zoom desktop application, click your profile picture, then 'Check for Updates' or look in 'About Zoom' to see the installed version number. Alternatively, check the Windows Programs and Features list or macOS Applications folder for the Zoom version.Affected if The installed Zoom version is below 5.15.5.
-
Check Zoom Rooms installationIf you deploy Zoom Rooms conference room systems, locate the Zoom Rooms controller application or the dedicated Zoom Rooms device and check its version in the settings or about section.Affected if Zoom Rooms version is below 5.15.5.
-
Verify network exposureDetermine if the Zoom client or SDK is configured to accept incoming network connections or if it communicates over network interfaces beyond localhost. Check firewall rules and client settings for any non-default network binding configurations.Affected if The Zoom client or SDK has enabled network listening or is accessible over network interfaces beyond typical client-server communication.
You are affected if any Zoom Meeting Software, Zoom Rooms, or Zoom Client SDK in your environment is installed at a version below 5.15.5 and the network-facing components are in use.
