CVE-2023-5111Public exploitNetwork attack vector

Browser script execution via featured type 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 via an admin request. The /admin/featured-types/save endpoint accepts featured_type_name[1] without sufficient neutralization, causing supplied markup to execute when the affected page is accessed. Low-privileged access and user interaction are required, and the demonstrated consequence is script execution in the victim's browser context.
