CVE-2022-45217Public exploitNetwork attack vector

Script execution via crafted Level parameter

Published Dec 7, 2022 · Updated Apr 23, 2025

Cross-site scripting in Book Store Management System 1.0.0 allows remote authenticated users to execute scripts through the Level field. The Add New System User module accepts the crafted Level value as page-generating input without neutralizing executable HTML or JavaScript. A low-privilege account and another user's interaction are required, exposing data and permitting page-content changes within that user's session.
