CVE-2022-28056Network attack vector

Unauthenticated system reinstallation via installer Add function

Published May 2, 2022 · Updated Aug 3, 2024

System reinstallation in ShopXO 2.2.5 and earlier allows remote attackers to overwrite application state through the web installer. The public record identifies the Add function in app/install/controller/Index.php but does not disclose which authorization or installed-state check fails. Unauthenticated network access is sufficient; successful reinstallation can replace configuration and interrupt the deployed storefront.
