VSFTPD v2.3.4 Exploit | Backdoor Command Execution | CVE-2011-2523

This is an exploit recorded back in 2011 that took advantage of Unix/Linux users. There was a vulnerability in the FTP server. The vulnerability was in the download of the VSFTPD version 2.3.4 from a website that has long since been taken down.

Hackers were able to login to the server using a smiley face, colon and a closing parentheses, :). The attacker could switch the default FTP port, 21, to port 6200 and establish a backdoor connection. The video showing a demonstration of the exploit using Metasploit and NetCat is on Patreon.
