Impact
CSRF vulnerability allowing attackers to change the state of an order’s adjustments if they hold its number, and the execution happens on a store administrator’s computer.
Reproduction steps:
- Take an order’s number.
- Log in as an administrator.
- Visit that order’s adjustments section (Orders -> {Click on number} -> Adjustments) and check that its adjustments are finalized (closed padlock under the State column).
- On another tab, visit
{your_site_url}/admin/orders/{order_number}/adjustments/unfinalize
. - Notice how the adjustments are unfinalized (open padlock), even if the previous was a
GET
request which could have been linked from any other site. - Visit
{your_site_url}/admin/orders/{order_number}/adjustments/finalize
. - Notice how the adjustments are again finalized.
That happened because both routes were handled as GET
requests, which are skipped by Rails anti-forgery protection.
