Cross-Site Scripting (XSS) Stored endpoint 'adicionar_tipo_quadro_horario.php' parameter 'tipo' in WeGIA

WeGIA is an open source web manager with a focus on the Portuguese language and charitable institutions. A Stored Cross-Site Scripting (XSS) vulnerability was identified in the adicionar_tipo_quadro_horario.php endpoint of the WeGIA application. This vulnerability allows attackers to inject malicious scripts into the tipo parameter. The injected scripts are stored on the server and executed automatically whenever the affected page is accessed by users, posing a significant security risk. The application fails to properly validate and sanitize user inputs in the adicionar_tipo_quadro_horario.php parameter. 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. This issue has been addressed in version 3.2.6. All users are advised to upgrade. There are no known workarounds for this vulnerability.
