|---|
| Description | Multiples Stored Cross-Site Scripting (XSS) in educar_calendario_dia_motivo_cad.php
Summary
Multiples Stored Cross-Site Scripting (XSS) vulnerability was identified in the /intranet/educar_calendario_dia_motivo_cad.php endpoint of the i-Educar application. This vulnerability allows attackers to inject malicious scripts into the nm_motivo 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_dia_motivo_cad.php
Parameter: nm_motivo, descricao
Trigger Page: /intranet/educar_turma_tipo_lst.php
Other Affected Endpoint: /intranet/educar_calendario_dia_motivo_ det.php?cod_calendario_dia_motivo=[id]
The application fails to properly validate and sanitize user inputs in the nm_motivo 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.

Access vulnerable endpoint and select default option in first and second fields. Insert the payload in third field ("Motivo") and fifth field ("Descição"). Choose and type any values in other required fields, click on "Salvar" and the trigger page will be activated automatically.
