Descriptions

A vulnerability in the Secure Copy Protocol (SCP) server of Cisco Enterprise NFV Infrastructure Software (NFVIS) could allow an authenticated, remote attacker to access the shell of the underlying Linux operating system on the affected device. The vulnerability is due to improper input validation of command arguments. An attacker could exploit this vulnerability by using crafted arguments when opening a connection to the affected device. An exploit could allow the attacker to gain shell access with a non-root user account to the underlying Linux operating system on the affected device. Due to the system design, access to the Linux shell could allow execution of additional attacks that may have a significant impact on the affected system. This vulnerability affects Cisco devices that are running release 3.7.1, 3.6.3, or earlier releases of Cisco Enterprise NFV Infrastructure Software (NFVIS) when access to the SCP server is allowed on the affected device. Cisco NFVIS Releases 3.5.x and 3.6.x do allow access to the SCP server by default, while Cisco NFVIS Release 3.7.1 does not. Cisco Bug IDs: CSCvh25026.

Una vulnerabilidad en el servidor Secure Copy Protocol (SCP) de Cisco Enterprise NFV Infrastructure Software (NFVIS) podría permitir que un atacante remoto autenticado aceda al shell del sistema operativo Linux subyacente en el dispositivo afectado. La vulnerabilidad se debe a una validación de entrada incorrecta de algunos argumentos de comandos. Un atacante podría explotar esta vulnerabilidad empleando argumentos manipulados al abrir una conexión al dispositivo afectado. Su explotación con éxito podría permitir que el atacante obtenga acceso shell con una cuenta de usuario no root al sistema operativo Linux subyacente en el dispositivo afectado. Debido al diseño del sistema, el acceso al shell de Linux podría permitir la ejecución de ataques adicionales que podrían tener un impacto significativo en el sistema afectado. Esta vulnerabilidad afecta a los dispositivos Cisco que ejecutan las versiones 3.7.1, 3.6.3 o anteriores de Cisco Enterprise NFV Infrastructure Software (NFVIS) cuando el acceso al servidor SCP está permitido en el dispositivo afectado. Cisco NFVIS Releases 3.5.x y 3.6.x permiten el acceso al servidor serSCP por defecto, mientras que Cisco NFVIS Release 3.7.1 no lo hace. Cisco Bug IDs: CSCvh25026.
