Detailsinfo

A vulnerability has been found in WWBN AVideo up to e01e41ecc and classified as problematic. Affected by this vulnerability is the function Live::canRestream of the file plugin/Live/view/Live_restreams/getLiveKey.json.php of the component Live Plugin. The manipulation of the argument token with an unknown input leads to a improper authentication vulnerability. The CWE definition for the vulnerability is CWE-287. When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. As an impact it is known to affect confidentiality. The summary by CVE is:

AVideo (current commit e01e41ecc and earlier) exposes stream credentials through the plugin/Live/view/Live_restreams/getLiveKey.json.php endpoint. Supplying a 'token' request parameter waives both the Live::canRestream() access gate and the restream ownership check, causing the endpoint to return any restream's stream_key and stream_url (credentials for external platforms such as YouTube, Facebook, and Twitch) without authentication. The token is merely encryptString() of an integer id with no user binding, expiry, or authentication tag. Because encryption uses AES-256-CBC with a deterministic IV and no MAC, and because intval() accepts any string beginning with a digit, an unauthenticated attacker can forge valid tokens using the public encryption oracle in view/url2Embed.json.php, disclosing arbitrary users' stream credentials.
