This vulnerability has a CVSS 3.1 base score of 6.8, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

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.
