| الوصف | Multiples Stored Cross-Site Scripting (XSS) in educar_calendario_anotacao_cad.php
Summary
Multiples Stored Cross-Site Scripting (XSS) vulnerability was identified in the /intranet/educar_calendario_anotacao_cad.php endpoint of the i-Educar application. This vulnerability allows attackers to inject malicious scripts into the nm_anotacao and descricao 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: /intranet/educar_calendario_anotacao_cad.php
Parameter: nm_anotacao, descricao
Trigger Page: /intranet/educar_calendario_anotacao_lst.php
The application fails to properly validate and sanitize user inputs in the nm_anotacao and descricao 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.
