提交 #618639: Portabilis i-Educar 2.10 Cross Site Scripting

Summary
A Stored Cross-Site Scripting (XSS) vulnerability was identified in the agenda.php endpoint of the I-educar application 2.8,2.9 and 2.10. This vulnerability allows attackers to inject malicious scripts into the agenda_rap_conteudo and agenda_rap_titulo parameters. The injected scripts are stored on the server and executed automatically whenever the affected page is accessed by users, posing a significant security risk.

Details
Vulnerable Endpoint: agenda.php Parameters: agenda_rap_conteudo and agenda_rap_titulo

The application fails to properly validate and sanitize user inputs in the agenda_rap_conteudo and agenda_rap_titulo parameters. This lack of validation allows attackers to inject malicious scripts, which are then stored on the server. Whenever the affected page is accessed, the malicious payload is executed in the victim's browser, potentially compromising the user's data and system.
