WinVNC Web Server GET Overflow

Description

This module exploits a buffer overflow in the AT&T WinVNC version <= v3.3.3r7 web server. When debugging mode with logging is enabled (non-default), an overly long GET request can overwrite the stack. This exploit does not work well with VNC payloads!

Module Options

To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':

msf > use exploit/windows/vnc/winvnc_http_get
msf exploit(winvnc_http_get) > show targets
    ...targets...
msf exploit(winvnc_http_get) > set TARGET < target-id >
msf exploit(winvnc_http_get) > show options
    ...show and set options...
msf exploit(winvnc_http_get) > 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.
