VU#756733: Calix GS7 XGS GS5239XG residential router contains missing authentication vulnerability
CERT/CC warns Calix GS7 XGS GS5239XG routers on firmware EXOS/6.6.47 expose an unauthenticated UPnP WANIPConnection service on the public WAN interface.
CERT/CC issued VU#756733 for a missing authentication vulnerability in the Calix GS7 XGS GS5239XG residential gateway running EXOS/6.6.47. The device's UPnP service, implemented with MiniUPnPd 2.3.7, is exposed on the WAN interface by default and does not require authentication, potentially letting remote attackers alter port mappings through the WANIPConnection service. The flaw affects routing, NAT, and firewall functionality for home networks.
