      "value": "A vulnerability in the API gateway of the Cisco Digital Network Architecture (DNA) Center could allow an unauthenticated, remote attacker to bypass authentication and access critical services. The vulnerability is due to a failure to normalize URLs prior to servicing requests. An attacker could exploit this vulnerability by submitting a crafted URL designed to exploit the issue. A successful exploit could allow the attacker to gain unauthenticated access to critical services, resulting in elevated privileges in DNA Center. This vulnerability affects Cisco DNA Center Software Releases prior to 1.1.2. Cisco Bug IDs: CSCvi09394."

      "value": "Una vulnerabilidad en el gateway API de Cisco Digital Network Architecture (DNA) Center podría permitir que un atacante remoto no autenticado omita la autenticación y acceder a servicios críticos. La vulnerabilidad se debe a un error a la hora de normalizar URL antes de las peticiones de servicio. Un atacante podría explotar esta vulnerabilidad enviando una URL diseñada para explotar este problema. Su explotación con éxito podría permitir que el atacante obtenga acceso no autenticado a servicios críticos, lo que resulta en privilegios elevados en DNA Center. Esta vulnerabilidad afecta a Cisco DNA Center Software si ejecuta cualquier distribución anterior a 1.1.2. Cisco Bug IDs: CSCvi09394."
