      "value": "WWBN AVideo is an open source video platform. In versions up to and including 29.0, plugin/MobileManager/oauth2.php completes an OAuth login by sending an HTTP 302 Location: oauth2Success.php?user=<email>&pass=<HASH> where <HASH> is the victim's stored password hash (md5(hash(\"whirlpool\", sha1(password)))) read directly from the users table. AVideo's own login endpoint (objects/login.json.php) accepts an encodedPass=1 flag that bypasses hashing and performs a direct string comparison between the supplied value and the stored hash. Anyone who captures the redirect URL — via server logs, referrer leakage, or browser history — therefore obtains a credential equivalent to the plaintext password and can fully take over the account, including admin accounts. Commit 977cd6930a97571a26da4239e25c8096dd4ecbc1 contains an updated fix."

      "value": "WWBN AVideo es una plataforma de video de código abierto. En versiones hasta la 29.0 inclusive, plugin/MobileManager/oauth2.php completa un inicio de sesión OAuth enviando una ubicación HTTP 302: oauth2Success.php?user=[email]&pass=[HASH] donde [HASH] es el hash de la contraseña almacenada de la víctima (md5(hash(“whirlpool”, sha1(contraseña)))) leído directamente de la tabla de usuarios. El propio endpoint de inicio de sesión de AVideo (objects/login.json.php) acepta una bandera encodedPass=1 que omite el hashing y realiza una comparación directa de cadenas entre el valor proporcionado y el hash almacenado. Cualquiera que capture la URL de redirección - a través de registros del servidor, fuga de referer o historial del navegador - por lo tanto, obtiene una credencial equivalente a la contraseña en texto plano y puede tomar el control total de la cuenta, incluidas las cuentas de administrador. El commit 977cd6930a97571a26da4239e25c8096dd4ecbc1 contiene una corrección actualizada."
