: A repository containing simple proof-of-concept (PoC) scripts to demonstrate the vulnerability.

The following article provides the technical details, history, and relevant GitHub links for the most notorious vsftpd exploit, which is version 2.3.4. The Notorious vsftpd 2.3.4 Backdoor (CVE-2011-2523)

Are you setting up a specific (like Metasploitable 2 or an HackTheBox instance)? vsftpd 208 exploit github link

Always check the MD5/SHA256 checksums of source code before compiling. If you are interested, I can:

injected into the source code by an unknown attacker who compromised the official vsftpd download site between June 30 and July 3, 2011. How it works

The script asks for the IP interactively and works even on systems where the FTP banner does not explicitly show the version. Always check the MD5/SHA256 checksums of source code

Version 2.0.8 is frequently referenced in VulnHub CTF writeups as a service running on target machines like "Stapler," where the goal is usually to find misconfigurations rather than a direct code-execution exploit in that specific version. PwnHouse/OSVDB-73573/README.md at master - GitHub

If a user logs into the FTP server and provides a username ending with a smiley face—specifically :) —the backdoor is triggered. Version 2

The easiest way to test this vulnerability is by downloading , a deliberately vulnerable Linux virtual machine created by Rapid7 for security training. It includes the backdoored version of VSFTPD 2.3.4 out of the box. 2. Isolate the Network

(Note: The module name may vary slightly; check search vsftpd in msfconsole.)

Explain how to set up a environment to test this.

In late June 2011, an unknown attacker managed to compromise the master download server for
