mIRC PRIVMSG Handling Stack Buffer Overflow

Disclosed

Description

This module exploits a buffer overflow in the mIRC IRC Client v6.34 and earlier. By enticing a mIRC user to connect to this server module, an excessively long PRIVMSG command can be sent, overwriting the stack. Due to size restrictions, ordinal payloads may be necessary. This module is based on the code by SkD.

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.
