Detailed vulnerability description
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.
The injected content is reflected into the HTML response, and the advisory demonstrates that opening a crafted link can overlay the application interface with attacker-controlled iframe content.
