Cross-site request forgery (CSRF) vulnerability in util_system.html in Belkin N900 router allows remote attackers to hijack the authentication of administrators for requests that change configuration settings including passwords and remote management ports.

Belkin wireless routers Surf N150 Model F7D1301v1, N900 Model F9K1104v1, N450 Model F9K1105V2, and N300 Model F7D2301v1 generate a predictable default WPA2-PSK passphrase based on eight digits of the WAN MAC address, which allows remote attackers to access the network by sniffing the beacon frames.

The WPA2 implementation on the Belkin N900 F9K1104v1 router establishes a WPS PIN based on 6 digits of the LAN/WLAN MAC address, which makes it easier for remote attackers to obtain access to a Wi-Fi network by reading broadcast packets, a different vulnerability than CVE-2012-4366.

Multiple cross-site scripting (XSS) vulnerabilities in Belkin N900 router allow remote attackers to inject arbitrary web script or HTML via the (1) ssid2 parameter to wl_channel.html or (2) guest_psk parameter to wl_guest.html.

Symlink Traversal vulnerability in Belkin N900 due to misconfiguration in the SMB service.
