Descriptions

A vulnerability in role-based access control of Cisco Integrated Management Controller (IMC) Supervisor, Cisco UCS Director, and Cisco UCS Director Express for Big Data could allow a read-only authenticated, remote attacker to disable user accounts on an affected system. The vulnerability is due to incorrect allocation of the enable/disable action button under the role-based access control code on an affected system. An attacker could exploit this vulnerability by authenticating as a read-only user and then updating the roles of other users to disable them. A successful exploit could allow the attacker to disable users, including administrative users.

Una vulnerabilidad en el control de acceso basado en roles del Cisco Integrated Management Controller (IMC) Supervisor, Cisco UCS Director, y Cisco UCS Director Express for Big Data, podría permitir a un atacante remoto autenticado de solo lectura desactivar las cuentas de usuario sobre un sistema afectado.
