CVE-2023-43707Public exploitNetwork attack vector

Authenticated script execution via stored catalog-page name

Published Sep 30, 2023 · Updated Sep 23, 2024

Stored cross-site scripting in osCommerce 4.12.56860 allows remote authenticated users to execute JavaScript in another user's browser. The catalog-page editor stores the CatalogsPageDescriptionForm[1][name] value without neutralizing injected script markup and renders it as executable content. An authenticated attacker must alter a catalog-page name and have another user view the stored value, enabling actions or data access within that user's browser context.
