Store-owner privilege escalation via admin path check
Published Nov 24, 2021 · Updated Aug 3, 2024
Improper access control in EC-CUBE 2 series 2.11.2 through 2.17.1 allows remote authenticated users to alter system settings. The management session authorization routine resolves permission paths against a fixed admin directory, so store-owner accounts can bypass intended checks and reach system-setting actions. Exploitation requires a valid product login; the demonstrated consequence is integrity loss through unauthorized configuration changes, with no reported confidentiality or availability impact.
