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
Pexip Infinity before 23.4 has a lack of input validation, leading to temporary denial of service via H.323.

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 confidence

Pexip Infinity versions prior to 23.4 contain a lack of input validation vulnerability in the H.323 protocol handling. This allows remote attackers to cause a temporary denial of service by sending specially crafted H.323 messages that trigger the validation failure.

MitigationUpgrade Pexip Infinity to version 23.4 or later to obtain the fixed codebase with proper input validation for H.323 protocol messages.

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 Pexip Infinity version
    Log into the Pexip Infinity admin interface and navigate to 'About' or 'System > Overview' to view the installed version number. Alternatively, use the command line: 'pexip --version' or check the web UI footer.
    Affected if The installed version is any version prior to 23.4 (e.g., 23.3, 23.2, etc.)
  2. Verify H.323 protocol is enabled
    In the Pexip Infinity admin interface, go to 'Call Routing > Call Routing Profiles' or 'Locations > [Location] > Services' to inspect whether H.323 calling is enabled. Check for any H.323-related service configurations.
    Affected if H.323 protocol calling is enabled and the version is prior to 23.4
  3. Review H.323 gateway settings
    Navigate to 'Call Routing > H.323' or 'Conferencing > H.323 Gatekeeper' in the admin interface to review H.323 gateway or gatekeeper configuration settings.
    Affected if An H.323 gateway or gatekeeper is configured and the version is prior to 23.4

A user is affected if they are running Pexip Infinity version below 23.4 AND have H.323 protocol calling or gateway functionality enabled in their deployment.
