CVE-2023-1557Network attack vector

Authenticated restricted username-handler access via USERID

Published Mar 22, 2023 · Updated Aug 2, 2024

Improper access control in E-Commerce System 1.0 allows remote authenticated users to reach restricted username handling via USERID. The admin/user/controller.php?action=edit endpoint trusts a caller-supplied USERID when selecting the target, but the precise missing authorization check is undisclosed. A valid low-privilege session is required; the confirmed consequence is unauthorized access to the username handler, while the exact data exposure or modification remains undisclosed.
