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 `remuneracao.php` endpoint of the WeGIA application. This vulnerability allows attackers to inject malicious scripts into the `descricao` 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 `remuneracao.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.
The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
