Some firewall configurations may block the outgoing connection to port 6200. In that case, the exploit fails. This is why GitHub scripts sometimes include a "reverse shell" variation, where the target connects back to you instead.

: Several repositories provide rewritten scripts or dedicated labs for practice: vsftpd-backdoor-exploit

The vsftpd 2.3.4 backdoor, often mistakenly referred to as a "2.0.8 exploit" in CTF challenges, allows remote command execution by logging in with a username ending in :) , which spawns a shell on port 6200.
