This module exploits a remote buffer overflow vulnerability on several D-Link routers. The vulnerability exists in the handling of HTTP queries to the authentication.cgi with long password values. The vulnerability can be exploitable without authentication. This module has been tested successfully on D-Link firmware DIR645A1_FW103B11. Other firmwares such as the DIR865LA1_FW101b06 and DIR845LA1_FW100b20 are also vulnerable.

To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':
msf > use exploit/linux/http/dlink_authentication_cgi_bof
msf exploit(dlink_authentication_cgi_bof) > show targets
...targets...
msf exploit(dlink_authentication_cgi_bof) > set TARGET < target-id >
msf exploit(dlink_authentication_cgi_bof) > show options
...show and set options...
msf exploit(dlink_authentication_cgi_bof) > exploit
Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
