This vulnerability is due to improper handling of XML External Entity (XXE) entries when parsing certain XML files. An attacker could exploit this vulnerability by uploading a crafted XML file that contains references to external entities. A successful exploit could allow the attacker to retrieve files from the local system, resulting in the disclosure of sensitive information, or cause the web application to perform arbitrary HTTP requests on behalf of the attacker."}, {"lang": "es", "value": "Una vulnerabilidad en la interfaz de administraci\u00f3n basada en web de Cisco Identity Services Engine (ISE) podr\u00eda permitir a un atacante remoto autenticado acceder a informaci\u00f3n confidencial o realizar un ataque de tipo server-side request forgery (SSRF) mediante un dispositivo afectado.
