| Summary | Snipe-IT: Maintenance Record Disclosure via Missing Authorization on GET ### Impact Any activated account in a company can read every maintenance record for that company (asset tag, supplier, purchase cost, free-text notes, dates) without holding any asset or maintenance permission. ## Summary `MaintenancesController::show()` renders a maintenance record without any authorization check. Every other action in the controller authorizes against the asset; `show()` does not. Any user in the asset's company can read maintenance detail (asset tag, supplier, purchase cost, notes, dates) by visiting `/maintenances/{id}`, regardless of permissions. ## Details ```php public function show(Maintenance $maintenance): View|RedirectResponse { return view('maintenances.view')->with('maintenance', $maintenance); } ``` No `authorize()` call. The sibling actions all gate on the asset: `index()` calls `authorize('view', Asset::class)` (line 33), and `edit()`/`update()`/`destroy()` call `authorize('update', $maintenance->asset)` (lines 139, 166, 286). The route is registered with only the auth guard: ```php Route::resource('maintenances', MaintenancesController::class, ['middleware' => ['auth']]); ``` (`routes/web/hardware.php:185`). Route-model binding still applies the company scope, so the read is bounded to the caller's company; the absent permission gate is the defect. Maintenance IDs are sequential and visible in the record URL. ## Proof of concept 1. As an administrator, create an asset in a company (here, `CompanyA`). Open the asset, choose Maintenances > Create, and add a record: name `MntA2`, supplier `SupA`, a purchase cost, and notes. The saved record opens at `/maintenances/{id}`. 2. As the administrator, create a test user assigned to CompanyA, with **every permission left unchecked**. Activate the account. 3. In a separate browser session, log in as the test user. Confirm it is unprivileged: the Assets and Maintenances navigation items are absent, and browsing to `/hardware` returns 403. 4. In the address bar, browse to `http://<host>/maintenances/{id}`. Observed: the maintenance view renders in full for the unprivileged account. ``` GET /maintenances/5 -> HTTP 200 OK Renders the "Maintenance" detail page for MntA2: Asset: AssetA Supplier: SupA Cost: <value> Notes: <text> Dates: <...> GET /hardware -> HTTP 403 (same account, asset list is gated) GET /maintenances -> HTTP 403 (same account, maintenance list is gated) GET /maintenances/2 -> HTTP 302 (record in CompanyB; company scope still hides it) ``` - The `test` account holds zero permissions and still reads the record. - Only the unguarded `show` route leaks: the list view and the asset pages return 403 for the same account. - A maintenance in a different company (CompanyB) redirects away, confirming the FMCS company scope still holds. ### Patches Patched in https://github.com/grokability/snipe-it/commit/69c50aa2aee25f837626556b4f4f3d05ec7ace96 |
