A Reflected Cross-site Scripting (XSS) vulnerability exists in the themeSet.php file of ProjectsAndPrograms School Management System 1.0. The application fails to sanitize user-supplied input in the theme POST parameter, allowing an attacker to inject and execute arbitrary JavaScript in a victim's browser.
The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
