CVE-2021-46070Public exploitNetwork attack vector

Authenticated script execution via unsanitized service fields

Published Jan 6, 2022 · Updated Aug 4, 2024

Stored cross-site scripting in Vehicle Service Management System 1.0 allows remote authenticated users to execute script in a viewing user's browser. The Service Requests form stores Owner Contact, Address, Vehicle Name, Vehicle Registration Number, and Vehicle Model values without neutralizing script markup, then renders them in request and Report views. Management-panel access is required to save the payload, and later viewing of the stored request triggers the injected JavaScript in that viewer's browser.
