The System Dashboard plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the Filename parameter in all versions up to, and including, 2.8.15 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick an administrative user into performing an action such as clicking on a link.
The System Dashboard WordPress plugin before 2.8.15 does not validate user input used in a path, which could allow high privilege users such as admin to perform path traversal attacks an read arbitrary files on the server
The System Dashboard WordPress plugin before 2.8.15 does not sanitise and escape some parameters when outputting them in the page, which could allow unauthenticated users to perform Cross-Site Scripting attacks.
