This module exploits a stack buffer overflow in fingerd on 4.3BSD. This vulnerability was exploited by the Morris worm in 1988-11-02. Cliff Stoll reports on the worm in the epilogue of The Cuckoo's Egg. Currently, only bsd/vax/shell_reverse_tcp is supported.

To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':
msf > use exploit/bsd/finger/morris_fingerd_bof
msf exploit(morris_fingerd_bof) > show targets
...targets...
msf exploit(morris_fingerd_bof) > set TARGET < target-id >
msf exploit(morris_fingerd_bof) > show options
...show and set options...
msf exploit(morris_fingerd_bof) > 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.
