CVE-2023-3660Public exploitNetwork attack vector

Administrator-session script execution via unneutralized username

Published Jul 13, 2023 · Updated Oct 23, 2024

Cross-site scripting in CampCodes Retro Cellphone Online Store 1.0 allows remote authenticated users to execute script via the un parameter. The /admin/add_user_modal.php endpoint renders the un username value in generated HTML without neutralizing browser-executable content. An authenticated administrator must submit the crafted parameter and a user must open the response; injected script then runs in that user's application origin.
