Security Test Results - IDOR Protection Complete

Date: 2025-12-31 Focus: Profile Data Export IDOR Protection + Cross-Guard Security Test Database: timebank_cc_2 (development database with real data)

Executive Summary

STATUS: ✅ ALL TESTS PASSING (100%)

All 5 profile data export methods are now fully protected against IDOR (Insecure Direct Object Reference) vulnerabilities with comprehensive test coverage across all profile types (User, Organization, Bank).

Critical Security Fix: Added cross-guard attack prevention to ProfileAuthorizationHelper, blocking unauthorized access when users attempt to access profiles on different authentication guards.

Security Improvements Implemented

1. ProfileAuthorizationHelper Enhancement

File: app/Helpers/ProfileAuthorizationHelper.php Lines: 63-101

NEW: Cross-Guard Attack Prevention

// IMPORTANT: Verify guard matches profile type to prevent cross-guard attacks
// Even if the user has a relationship with the profile, they must be
// authenticated on the correct guard

Expected guard mapping:
- Bank profiles → require 'bank' guard authentication
- Organization profiles → require 'organization' guard authentication
- Admin profiles → require 'admin' guard authentication
- User profiles → require 'web' guard authentication

Protection Logic:

  1. Determines expected guard for target profile type
  2. Checks which guard current authentication is from
  3. Blocks access if guards don't match
  4. Logs cross-guard attempts for security monitoring

Example Attack Blocked:

  • User authenticated on 'web' guard
  • User IS a manager of Bank ID 1 (valid database relationship)
  • User manipulates session: activeProfileType = Bank, activeProfileId = 1
  • OLD BEHAVIOR: Access granted (database relationship exists)
  • NEW BEHAVIOR: 403 Forbidden (wrong guard) + logged warning

2. ExportProfileData Protection

File: app/Http/Livewire/Profile/ExportProfileData.php

All 5 export methods now protected:

public function exportTransactions($type)  // Line 45
public function exportProfileData($type)   // Line 147
public function exportMessages($type)      // Line 283
public function exportTags($type)          // Line 374
public function exportContacts($type)      // Line 441

Authorization Flow (Applied to all methods):

  1. Get active profile from session
  2. Validate profile exists
  3. ProfileAuthorizationHelper::authorize($profile) ← CRITICAL
  4. Validate export format
  5. Perform export operation

Key Improvement: Authorization check happens BEFORE format validation and export operations, ensuring no data exposure on failed authorization.

Attack Scenarios Tested & Blocked

Session Manipulation Attacks ✅

Attack: User modifies session variables to access another user's data

session(['activeProfileType' => User::class, 'activeProfileId' => $victim_id]);

Protection: ProfileAuthorizationHelper validates database ownership Result: 403 Forbidden + logged warning

Cross-Profile Attacks ✅

Attack: Organization 1 manipulates session to access Organization 2's data

// Authenticated as Organization 1
session(['activeProfileType' => Organization::class, 'activeProfileId' => 2]);

Protection: Database relationship validation (user must be member of organization) Result: 403 Forbidden

Cross-Guard Attacks ✅ (NEW)

Attack: User on 'web' guard attempts to access Bank profile (even if they're a manager)

$this->actingAs($user, 'web');  // Authenticated on web guard
session(['activeProfileType' => Bank::class, 'activeProfileId' => 1]);

Protection: Guard matching validation Result: 403 Forbidden + "Cross-guard access attempt blocked" log

Unauthenticated Access ✅

Attack: No authentication but session manipulation

// No actingAs() call
session(['activeProfileType' => User::class, 'activeProfileId' => 1]);

Protection: Authentication check before authorization Result: 401 Unauthorized
