The default configuration of Widcomm Bluetooth for Windows (BTW) 4.0.1.1500 and earlier, as installed on Belkin Bluetooth Software 1.4.2 Build 10 and ANYCOM Blue USB-130-250 Software 4.0.1.1500, and possibly other devices, sets null Authentication and Authorization values, which allows remote attackers to send arbitrary audio and possibly eavesdrop using the microphone via the Hands Free Audio Gateway and Headset profile.
Belkin F5D7232-4 and F5D7230-4 wireless routers with firmware 4.03.03 and 4.05.03, when a legitimate administrator is logged into the web management interface, allow remote attackers to access the management interface without authentication.
Belkin 54g wireless routers do not properly set an administrative password, which allows remote attackers to gain access via the (1) Telnet or (2) web administration interfaces.
Belkin 54G (F5D7130) wireless router allows remote attackers to access restricted resources by sniffing URIs from UPNP datagrams, then accessing those URIs, which do not require authentication.
Belkin F5D5230-4 4-Port Cable/DSL Gateway Router 1.20.000 modifies the source IP address of internal packets to that of the router's external interface when forwarding a request from an internal host to an internal web server, which allows remote attackers to hide which host is being used to access the web server.
Belkin F5D6130 Wireless Network Access Point running firmware AP14G8 allows remote attackers to cause a denial of service (connection loss) by sending several SNMP GetNextRequest requests.
