      "value": "A vulnerability in the External RESTful Services (ERS) API of the Cisco Identity Services Engine (ISE) could allow an authenticated, remote attacker to generate arbitrary certificates signed by the Internal Certificate Authority (CA) Services on ISE. This vulnerability is due to an incorrect implementation of role-based access control (RBAC). An attacker could exploit this vulnerability by crafting a specific HTTP request with administrative credentials. A successful exploit could allow the attacker to generate a certificate that is signed and trusted by the ISE CA with arbitrary attributes. The attacker could use this certificate to access other networks or assets that are protected by certificate authentication."

Esta vulnerabilidad es debido a una implementaci\u00f3n inadecuada del control de acceso basado en roles (RBAC). Un atacante podr\u00eda explotar esta vulnerabilidad al crear una solicitud HTTP espec\u00edfica con credenciales administrativas.

El atacante podr\u00eda usar este certificado para acceder a otras redes o activos que est\u00e1n protegidos por autenticaci\u00f3n de certificado."
