Description
The vulnerability allows a remote attacker to bypass authentication and control live streams.
The vulnerability exists due to improper authentication in plugin/Live/standAloneFiles/control.json.php when processing a user-supplied streamerURL parameter for token verification. A remote attacker can supply a crafted streamerURL that redirects token verification to an attacker-controlled server to bypass authentication and control live streams.
The issue can be used to drop active publishers, start or stop recordings, probe stream existence, and trigger server-side requests to attacker-controlled URLs.
