Snipe-IT: Stored XSS via Custom Field name in asset-list column headers
Impact
A user with the "customfields.create" permission can store HTML/JS in a Custom Field name, which is later rendered as an asset-list column title WITHOUT escaping at app/Presenters/AssetPresenter.php line 364 ('title' => $field->name) and injected into the table header by the bundled bootstrap-table plugin. It executes for anyone who opens an asset list (e.g. /hardware), including superusers, on page load with no interaction. Since "customfields.create" can be granted to non-superusers, a lower-privileged user gets script execution in a superuser's session -> privilege escalation.
STEPS TO REPRODUCE
- As a user with "customfields.create", create a Custom Field named:
<img src=x onerror=alert(1)> - Add the field to a fieldset that is associated with an asset model.
- Open
/hardware-> the payload executes on load.
DEMONSTRATED IMPACT An account holding ONLY "customfields.create" (HTTP 403 on /users) planted a payload that, when a superuser opened /hardware, issued an authenticated request in that session and granted the attacker's own account the "superuser" permission (afterwards: GET /users = 200, isSuperUser() = true).
ROOT CAUSE
- Blade {{ }} encodes the data-columns attribute, but the browser decodes it back before bootstrap-table reads the title; bootstrap-table then renders the header title unescaped because its table-level "escape" option defaults to false and is never enabled. (The per-column 'escape' => true covers cell values, not the header title.)
