  # Exploit Title: minaliC 2.0.0 - Denial of Service (DoS)
  # Discovery by: Fernando Mengali
  # Discovery Date: 03 january 2024
  # Vendor Homepage: http://minalic.sourceforge.net/
  # Notification vendor: No reported
  # Tested Version: minaliC 2.0.0
  # Tested on: Window XP Professional - Service Pack 2 and 3 - English
  # Vulnerability Type: Denial of Service (DoS)
  # Vídeo: https://www.youtube.com/watch?v=R_gkEjvpJNw
  
  #1. Description
  
  #This technique works fine against Windows XP Professional Service Pack 2 and 3 (English).
  #For this exploit I have tried several strategies to increase reliability and performance:
  #Jump to a static 'call esp'
  #Backwards jump to code a known distance from the stack pointer.
  #The server did not properly handle request with large amounts of data via method GET to web server.
  #The following request sends a large amount of data to the web server to process across method GET, the server will crash as soon as it is received and processed, causing denial of service conditions.
  #Successful exploitation of these issues allows remote attackers to crash the affected server, denying service to legitimate users.
  
  #2. Proof of Concept - PoC
