Name of the Vulnerable Software and Affected Versions Mercusys AC12G (EU) V1 firmware AC12G(EU) V1 200909
Description The UPnP AddPortMapping feature allows external ports to be forwarded to the router's own administration interface. This occurs because the system accepts the router's own IP (192.168.1.1) or localhost (127.0.0.1) as the InternalClient variable. An unauthenticated attacker on the local area network can expose the administration panel to the internet using a single SOAP request.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
