CVE-2023-45384Known exploitationNetwork attack vector

Unauthenticated code execution via unchecked PHP upload

Published Oct 19, 2023 · Updated Sep 12, 2024

Unrestricted file upload in KnowBand One Page SuperCheckout before 6.0.7 allows remote attackers to execute PHP through guest checkout. The SupercheckoutSupercheckoutModuleFrontController::saveFileTypeCustomField() method accepts a .php extension without blocking the executable file type. Guest access is sufficient; server-side execution can expose or alter store data, create administrator access, or interrupt the shop.
