CVE-2023-49540Public exploitNetwork attack vector

Browser script execution via unencoded customer names

Published Mar 1, 2024 · Updated Aug 6, 2024

Stored cross-site scripting in Book Store Management System 1.0 allows attackers to execute scripts through a crafted customer name. The transaction save endpoint stores the buyer_name value, and the history page renders that value as active HTML without neutralizing script markup. The published request includes a session cookie, and execution requires a management user to view transaction history, exposing that browser session to script-level data access and actions.
