# Version: 3.0.3

##### Vulnerability #####
|
|
|
|
Secure Notepad - Private 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.
