Browser script execution via unsanitized country name
Published Sep 30, 2023 · Updated Sep 20, 2024
Cross-site scripting in osCommerce 4.12.56860 allows remote authenticated users to execute scripts in another user’s browser. The administrative country-save handler accepts countries_name[1] without sufficient validation or output neutralization before the value reaches a generated page. Low-privileged access to the administrative handler and a user loading the affected page are required; successful exploitation runs attacker-controlled script in the site origin.
