Cross-site request forgery (CSRF) vulnerability in apply.cgi in Belkin N300 (F7D7301v1) router allows remote attackers to hijack the authentication of administrators for requests that modify configuration.

The Belkin N300 (F7D7301v1) router allows remote attackers to bypass authentication and gain privileges via vectors related to incorrect validation of the HTTP Authorization header.

Belkin N300 Dual-Band Wi-Fi Range Extender with firmware before 1.04.10 allows remote authenticated users to execute arbitrary commands via the (1) sub_dir parameter in a formUSBStorage request; pinCode parameter in a (2) formWpsStart or (3) formiNICWpsStart request; (4) wps_enrolee_pin parameter in a formWlanSetupWPS request; or unspecified parameters in a (5) formWlanMP, (6) formBSSetSitesurvey, (7) formHwSet, or (8) formConnectionSetting request.

Multiple cross-site scripting (XSS) vulnerabilities in Belkin N300 router allow remote attackers to inject arbitrary web script or HTML via the Guest Access PSK field to wireless_guest2_print.stm or other unspecified vectors.

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.

In Belkin N300 Firmware 1.00.08, the script located at /setting_hidden.asp, which is accessible before and after configuring the device, exhibits multiple remote command injection vulnerabilities. The following parameters in the [form name] form; [list vulnerable parameters], are not properly sanitized after being submitted to the web interface in a POST request. With specially crafted parameters, it is possible to inject a an OS command which will be executed with root privileges, as the web interface, and all processes on the device, run as root.
