CVE-2023-47309Network attack vector

Stored XSS via unescaped mobile number

Published Nov 15, 2023 · Updated Aug 29, 2024

Stored XSS in Nukium nkmgls before 3.0.2 allows remote authenticated users to execute JavaScript when an administrator views an order. NkmGlsCheckoutModuleFrontController::displayAjaxSavePhoneMobile stores the unvalidated gls_customer_mobile value, and a back-office Smarty template inserts it into an HTML attribute without escaping. Exploitation requires a paid GLS order and an administrator to open the affected back-office screen, exposing the administrator session to attacker-controlled script actions.
