CVE-2019-12633
Estado: ModificadaAlta (7.5)—
A vulnerability in Cisco Unified Contact Center Express (Unified CCX) could allow an unauthenticated, remote attacker to bypass access controls and conduct a server-side request forgery (SSRF) attack on a targeted system. The vulnerability is due to improper validation of user-supplied input on the affected system. An attacker could exploit this vulnerability by sending the user of the web application a crafted request. If the request is processed, the attacker could access the system and perform unauthorized actions.

La vulnerabilidad es debido a la comprobación inapropiada de la entrada suministrada por el usuario sobre el sistema afectado. Un atacante podría explotar esta vulnerabilidad mediante el envío al usuario de la aplicación web de una petición diseñada. Si la petición es procesada, el atacante podría acceder al sistema y realizar acciones no autorizadas."
