Description

This module exploits a stack buffer overflow in mIRC 6.1. By submitting an overly long and specially crafted URL to the 'irc' protocol, an attacker can overwrite the buffer and control program execution.

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/browser/mirc_irc_url
msf exploit(mirc_irc_url) > show targets
    ...targets...
msf exploit(mirc_irc_url) > set TARGET < target-id >
msf exploit(mirc_irc_url) > show options
    ...show and set options...
msf exploit(mirc_irc_url) > 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.
