WeGIA Stored Cross-Site Scripting Vulnerability in atendido_parentesco_adicionar.php

A stored cross-site scripting vulnerability has been identified in the WeGIA application, specifically within the atendido_parentesco_adicionar.php endpoint. This issue allows attackers to inject malicious scripts into the descricao parameter, which are then stored on the server. The injected scripts are executed automatically when the affected page is accessed by users, creating a significant security risk. The vulnerability affects WeGIA versions prior to 3.2.15 and has been patched in version 3.2.16.

Impact

Exploitation of this vulnerability allows for stored cross-site scripting, where injected scripts are executed in the context of the user accessing the page.

Reproduction

To reproduce this vulnerability, send a POST request to the atendido_parentesco_adicionar.php endpoint with a payload in the descricao parameter that includes a script tag. Once the payload is injected, it will be executed automatically when the page is accessed by users.

Remediation

Users can update to WeGIA version 3.2.16 to address this vulnerability.
