Descriptions

A vulnerability in the web-based management interface of Cisco Integrated Management Controller (IMC) Supervisor, Cisco UCS Director, and Cisco UCS Director Express for Big Data could allow an authenticated, remote attacker to execute arbitrary commands on the underlying Linux shell as the root user. Exploitation of this vulnerability requires privileged access to an affected device. The vulnerability is due to insufficient validation of user-supplied input by the web-based management interface. An attacker could exploit this vulnerability by logging in to the web-based management interface with administrator privileges and then sending a malicious request to a certain part of the interface.

Una vulnerabilidad en la interfaz de administración basada en la web de Cisco Integrated Management Controller (IMC) Supervisor, Cisco UCS Director,y Cisco UCS Director Express for Big Data podría permitir que un atacante remoto autenticado ejecute comandos arbitrarios en el shell Linux subyacente como raíz usuario. La explotación de esta vulnerabilidad requiere acceso privilegiado a un dispositivo afectado. La vulnerabilidad se debe a una validación insuficiente de la entrada proporcionada por el usuario por la interfaz de administración basada en la web. Un atacante podría aprovechar esta vulnerabilidad iniciando sesión en la interfaz de administración basada en la web con privilegios de administrador y luego enviando una solicitud maliciosa a cierta parte de la interfaz.

Cisco UCS Director, Cisco Integrated Management Controller Supervisor and Cisco UCS Director Express for Big Data suffer from default password, authentication bypass, and command injection vulnerabilities.
