Vulnerability details
The vulnerability allows a remote attacker to execute arbitrary code in the victim's browser and perform ui redressing.
The vulnerability exists due to cross-site scripting in html/memorando/insere_despacho.php when processing the id_memorando GET parameter. A remote attacker can send a specially crafted link to execute arbitrary code in the victim's browser and perform ui redressing.
