> DESCRIPTION

WWBN AVideo is an open source video platform. In versions up to and including 29.0, plugin/CloneSite/cloneClient.json.php echoes the local CloneSite shared secret ($objClone->myKey, a constant md5($global['systemRootPath'] . $global['salt'])) into the HTTP response body on every unauthenticated request. The unauthenticated error branch was intended to reject non-admin callers without a valid key, but the rejection message interpolates the expected key before die(). When the victim has CloneSite configured with a remote cloneSiteURL (standard federation/backup setup), the leaked myKey is exactly the credential that authenticates the victim to that remote server's cloneServer.json.php, allowing the attacker to impersonate the victim and trigger a full mysqldump of the remote's database to the remote's public videos/clones/ directory Commit e6566f56a28f4556b2a0a09d03717a719dcb49da contains an updated fix.
