Portabilis i-Educar Stored Cross-Site Scripting Vulnerability

A stored cross-site scripting vulnerability has been identified in Portabilis i-Educar version 2.10. The issue resides in the '/intranet/public_uf_cad.php' file, specifically within the 'nome' parameter. This vulnerability allows remote attackers to inject malicious scripts that are stored on the server and executed when the page is accessed by users. The lack of proper input validation and sanitization in the application enables this exploitation.

Impact

Exploitation of this vulnerability allows for stored cross-site scripting, where injected scripts are executed in the context of the user accessing the page. This could lead to session hijacking, theft of cookies, and execution of malicious scripts in the user's browser.

Reproduction

To reproduce this vulnerability, access the '/intranet/public_uf_cad.php' endpoint. Select 'Brasil' in the 'País' field, choose any option in the 'Sigla Uf' field, and insert a payload, such as an image tag with an 'onerror' event, into the 'Nome' field. After saving, the payload will be executed automatically when the '/intranet/public_uf_lst.php' page is accessed.
