Let us exploit try the below exploit.. Disclaimer: I did an intense NMAP scan for FTP port and did a couple of trial and errors before figuring out that the port 21 has the “vstfpd_234_backdoor” vulnerability that can be exploited: Exploiting Unix “vstfpd_234_backdoor” vulnerability of Metasploitable 2 using Armitage. The end result being, the exploited host now presents its shell prompt via which we were able to create our own directory.
