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.
Affected products
