CVE-2018-18541

Estado: ModificadaAlta (7.5)—

En Teeworlds en versiones anteriores a la 0.6.5, podrían falsificarse paquetes de conexión. No ha habido un desafío-respuesta involucrado en el build up de conexión. Un atacante remoto podría enviar paquetes de conexión desde una dirección IP suplantada y ocupar todos los slots del servidor o emplearlos para un ataque de reflexión mediante paquetes de descarga de mapas.
