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
VSeeFace through 1.13.38.c2 allows attackers to cause a denial of service (application hang) via a spoofed UDP packet containing at least 10 digits in JSON data.

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

VSeeFace through version 1.13.38.c2 contains a denial of service vulnerability in its UDP packet handling logic. Attackers can send spoofed UDP packets containing JSON data with at least 10 digits, which causes the application to hang. The vulnerability stems from insufficient input validation or improper handling of malformed JSON data received over UDP, a protocol that allows source address spoofing without authentication.

MitigationImplement strict input validation on all UDP packet data before JSON parsing, including length limits, character whitelisting, and exception handling for malformed input. Consider adding rate limiting or authentication mechanisms for UDP-based communication to prevent abuse.

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. Identify VSeeFace installation
    Look for VSeeFace application files on the system - check common installation directories such as Program Files, or search for executable files named VSeeFace or related files with .exe extension.
    Affected if VSeeFace is found installed on the system
  2. Determine installed version
    Open VSeeFace and navigate to its About or Help section to view the version number, or check the executable file properties for version information.
    Affected if The version is 1.13.38.c2 or any earlier version through 1.13.38.c2 (verify against affected range)
  3. Check if UDP communication is enabled
    Observe VSeeFace running and check network activity using tools like netstat or Wireshark to see if the application is listening on any UDP ports or actively receiving UDP packets.
    Affected if UDP ports are open or UDP traffic is being processed by VSeeFace

If VSeeFace version 1.13.38.c2 or earlier is installed AND the application has UDP communication enabled or is listening on UDP ports, the environment is affected by this CVE.

Mitigation

Implement strict input validation on all UDP packet data before JSON parsing, including length limits, character whitelisting, and exception handling for malformed input. Consider adding rate limiting or authentication mechanisms for UDP-based communication to prevent abuse.

Recommended fix Moderate confidence

Any version after 1.13.38.c2 (check official VSeeFace releases for the specific fixed version)

  1. 1. Identify the current VSeeFace version in use by checking the application or its installation directory
  2. 2. Download the latest version of VSeeFace from the official source (https://vseeface.icu/)
  3. 3. Backup any existing configuration files, custom assets, and settings before upgrading
  4. 4. Uninstall or replace the current VSeeFace installation with the newer version
  5. 5. Restore the backed-up configuration and settings
  6. 6. Test that the application starts and functions correctly
  7. 7. Verify that the application no longer hangs when receiving spoofed UDP packets with JSON data containing 10+ digits
