## Technical details

A local file read vulnerability in services_dyndns_edit.php allows authenticated users with the Dynamic DNS client privilege to specify a file:// URL as a custom update URL. When the _checkStatus() function logs the response to a non-matching Result Match string, file contents are written to the system log, readable by the attacker. This requires existing Dynamic DNS privileges and local network access but no additional authentication.
