Detailsinfo

A vulnerability was found in WWBN AVideo up to 29.0 and classified as problematic. Affected by this issue is an unknown function of the file plugin/MobileManager/oauth2.php of the component Password Hash Handler. The manipulation with an unknown input leads to a use of get request method with sensitive query strings vulnerability. Using CWE to declare the problem leads to CWE-598. The web application uses the HTTP GET method to process a request and includes sensitive information in the query string of that request. Impacted is confidentiality, integrity, and availability. CVE summarizes:

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=&pass= where 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.
