Affected Product Code Base

WeGIA < v3.2.0

Vulnerability Description

A stored Cross-Site Scripting (XSS) vulnerability was identified in the WeGIA application. This vulnerability allows unauthorized scripts to be executed within the user's browser context. Stored XSS is particularly critical, as the malicious code is permanently stored on the server and executed whenever a compromised page is loaded, affecting all users accessing this page.

POC

To reproduce the issue, insert the following payloads into the vulnerable field of the URL and save the changes:

<script>alert('Alert: XSS');</script>

After saving the input, the injected script will be stored on the server and automatically executed for any user accessing the html/geral/documentos_funcionario.php, confirming the stored XSS.

File: documentos_funcionario.php

Payload:

<script>alert('Alert: XSS');</script>

Trigger in: html/geral/documentos_funcionario.php

Endpoint: id
