Attackers can exploit this flaw when device authentication is disabled to persistently execute arbitrary script in the browser of any administrator who opens the web management interface, enabling theft of stored secrets such as web UI credentials, RTMP stream keys, publish URLs, and NFS/SMB share credentials, as well as hijacking of the authenticated session.
