CVE-2020-9016Public exploitNetwork attack vector

Authenticated browser script execution via reflected request inputs

Published Feb 16, 2020 · Updated Aug 4, 2024

Cross-site scripting in Dolibarr 11.0 allows remote authenticated users to execute script in another user's browser via crafted requests. The application reflects the joinfiles, topic, and code parameters or the HTTP Referer header into generated pages without neutralizing executable markup. A logged-in attacker must supply the payload and induce another user to view the affected response, enabling actions or data access within that user's session.
