cgi-bin/setupdns.exe on the Belkin F5D7230-4 router with firmware 9.01.10 does not require authentication, which allows remote attackers to perform administrative actions, as demonstrated by changing a DNS server via the dns11, dns12, dns13, and dns14 parameters. NOTE: it was later reported that F5D7632-4V6 with firmware 6.01.08 is also affected.
The control panel on the Belkin F5D7230-4 router with firmware 9.01.10 maintains authentication state by IP address, which allows remote attackers to bypass authentication by establishing a session from a source IP address of a previously authenticated user, a different vulnerability than CVE-2005-3802.
cgi-bin/setupvirtualserver.exe on the Belkin F5D7230-4 router with firmware 9.01.10 allows remote attackers to cause a denial of service (control center outage) via an HTTP request with invalid POST data and a "Connection: Keep-Alive" header.
The web server in Belkin Wireless G Plus MIMO Router F5D9230-4 does not require authentication for SaveCfgFile.cgi, which allows remote attackers to read and modify configuration via a direct request to SaveCfgFile.cgi.
