Summary
The Open eClass platform (formerly known as GUnet eClass) is a complete course management system. Prior to version 4.2, a Stored Cross-Site Scripting (XSS) vulnerability allows authenticated high-privileged users (teachers or administrators) to inject malicious JavaScript into multiple user-controllable input fields across the application, which is executed when other users access affected pages.
