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
WWBN AVideo is an open source video platform. In versions up to and including 26.0, the `createKeys()` function in the LoginControl plugin's PGP 2FA system generates 512-bit RSA keys, which have been publicly factorable since 1999. An attacker who obtains a target user's public key can factor the 512-bit RSA modulus on commodity hardware in hours, derive the complete private key, and decrypt any PGP 2FA challenge issued by the system — completely bypassing the second authentication factor. Additionally, the `generateKeys.json.php` and `encryptMessage.json.php` endpoints lack any authentication checks, exposing CPU-intensive key generation to anonymous users. Commit 00d979d87f8182095c8150609153a43f834e351e contains a patch.

Recommended fix Moderate confidence

Version greater than 26.0 that includes commit 00d979d87f8182095c8150609153a43f834e351e

  1. 1. Identify the currently running AVideo version (likely <= 26.0)
  2. 2. Navigate to the AVideo repository at https://github.com/WWBN/AVideo
  3. 3. Look for a release version newer than 26.0 that includes commit 00d979d87f8182095c8150609153a43f834e351e
  4. 4. Pull the latest code or download the updated release package
  5. 5. Backup the current installation database and files
  6. 6. Deploy the updated version containing the patch
  7. 7. Verify that the LoginControl plugin now uses RSA keys of at least 2048 bits
  8. 8. Confirm that generateKeys.json.php and encryptMessage.json.php now require authentication
