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
Sunshine is a self-hosted game stream host for Moonlight. Clients that experience a MITM attack during the pairing process may inadvertantly allow access to an unintended client rather than failing authentication due to a PIN validation error. The pairing attempt fails due to the incorrect PIN, but the certificate from the forged pairing attempt is incorrectly persisted prior to the completion of the pairing request. This allows access to the certificate belonging to the attacker.

Recommended fix Moderate confidence

Latest Sunshine release newer than 2024-05-27 that includes commit 5fcd07ecb1428bfe245ad6fa349aead476c7e772

  1. 1. Navigate to the Sunshine releases page on GitHub (https://github.com/LizardByte/Sunshine/releases)
  2. 2. Identify the latest stable release that is newer than the 2024-05-27 affected version
  3. 3. Download the release corresponding to your operating system
  4. 4. Uninstall the current (vulnerable) version of Sunshine
  5. 5. Install the newer version that includes the fix from commit 5fcd07ecb1428bfe245ad6fa349aead476c7e772
  6. 6. After installation, verify the pairing process works correctly - ensure certificates are only persisted after successful PIN validation
  7. 7. If using existing paired clients, consider re-pairing to ensure clean state
Caveat Minor: Existing paired clients should continue to work, but re-pairing may be recommended for security verification
