CVE-2025-57763Public exploitNetwork attack vector

Browser script execution via unsanitized sccs reflection

Published Aug 21, 2025 · Updated Aug 21, 2025

Reflected XSS in WeGIA before 3.4.7 allows remote attackers to execute scripts in a victim's browser via the sccs parameter. The insere_despacho.php endpoint returns the GET parameter directly in its HTML response without validating or neutralizing attacker-controlled markup. Exploitation requires a victim to open the crafted request, after which the script can read or modify data and perform actions available to that victim's WeGIA session.
