Technical details
A reflected Cross-Site Scripting (XSS) vulnerability exists in WeGIA versions prior to 3.7.0 within the 'lista_arquivos_etapa.php' component. The root cause is the improper neutralization of the 'id_processo' GET parameter, which is directly echoed into a hidden HTML input field without sanitization or encoding. An unauthenticated remote attacker can exploit this by inducing a victim to visit a crafted URL containing malicious JavaScript. Successful exploitation allows for the execution of arbitrary code in the context of the victim's browser session, potentially leading to session hijacking (CWE-79). The issue is resolved in version 3.7.0.
