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
No proper validation of the length of user input in http_server_get_content_type_from_extension.

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.

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.

Recommended fix Moderate confidence

Zephyr 3.7.1 or later (any version > 3.7.0 that includes the security fix)

  1. 1. Identify all Zephyr-based devices/systems using Zephyr version 3.7.0 or earlier that implement the HTTP server functionality
  2. 2. Review the application's code to identify any calls to http_server_get_content_type_from_extension function
  3. 3. If using Zephyr's HTTP server module, ensure no untrusted user input is passed to content type extension parsing until patched
  4. 4. Update Zephyr to version 3.7.1 or later which contains the fix for proper length validation in http_server_get_content_type_from_extension
  5. 5. After upgrading, rebuild and redeploy the firmware to affected devices
Caveat Verify any custom HTTP server extensions or content type handling code remains compatible with the updated version
