Authenticated script injection via unsanitized id parameter

Published Apr 15, 2023 · Updated Feb 5, 2025

Cross-site scripting in SourceCodester Vehicle Service Management System 1.0 allows remote authenticated users to inject script via id. The /classes/Users.php handler accepts the id parameter without adequate neutralization and places it in a generated web page. Execution requires a victim to view that page, where the script runs in the site's browser context and can expose session cookies.
