CVE-2021-46079Public exploitNetwork attack vector

Authenticated HTML injection via unrestricted image uploads

Published Jan 6, 2022 · Updated Aug 4, 2024

Unrestricted file upload in Sourcecodester Vehicle Service Management System 1.0 allows remote authenticated users to inject HTML. The account-profile, User List, system-logo, and website-cover handlers accept an HTML file through image fields and store it for direct browser retrieval without restricting the file type. Administrator access is required to reach the documented upload forms, and the injected content executes only when the stored avatar or branding file is opened.
