CVE-2023-43712Public exploitNetwork attack vector

Browser script execution via access_levels_name injection

Published Sep 30, 2023 · Updated Sep 23, 2024

Cross-site scripting in osCommerce 4.12.56860 allows remote authenticated users to execute scripts in another user's browser. The /admin/adminfiles/submit endpoint accepts script-bearing markup in access_levels_name and places it into executable page content. Administrative access and a victim opening the affected view are required; the script runs with the origin's browser privileges and can read or alter session-accessible data.
