solidus_backend

SEVERITY

PATCHED VERSIONS

  • ~> 2.11.16

  • >= 3.1.6

DESCRIPTION

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.

Patches

Users should upgrade to solidus_backend v3.1.6, v3.0.6, or v2.11.16, depending on the major and minor versions in use.
