Portabilis i-Educar Cross-Site Scripting Vulnerability in User List Endpoint

A reflected cross-site scripting vulnerability has been identified in Portabilis i-Educar versions through 2.9. The issue arises in the `/intranet/educar_usuario_lst.php` file, where the application fails to properly validate and sanitize user inputs for the `nm_pessoa`, `matricula`, and `matricula_interna` parameters. This lack of input validation allows for the injection of malicious scripts, which are then executed in the context of the user's browser. The vulnerability can be exploited remotely, and a public exploit is available.

Impact

Exploitation of this vulnerability allows for reflected cross-site scripting, where injected scripts are executed in the context of the user's browser. This can lead to various consequences, such as stealing cookies, manipulating account information, or executing malicious code on the user's device.

Reproduction

To reproduce this vulnerability, send a GET request to the `/intranet/educar_usuario_lst.php` endpoint with a crafted payload in one of the vulnerable parameters: `nm_pessoa`, `matricula`, or `matricula_interna`. The injected script will be reflected in the response and executed in the browser.
