Descriptions

A vulnerability in the CLI of Cisco NX-OS System Software could allow an authenticated, local attacker to perform a command injection attack. An attacker would need valid administrator credentials to perform this exploit. The vulnerability is due to insufficient input validation of command arguments. An attacker could exploit this vulnerability by injecting crafted command arguments into a vulnerable CLI command. An exploit could allow the attacker to execute arbitrary commands as root. This vulnerability affects the following products running Cisco NX-OS System Software: Multilayer Director Switches, Nexus 2000 Series Fabric Extenders, Nexus 3000 Series Switches, Nexus 3500 Platform Switches, Nexus 5000 Series Switches, Nexus 5500 Platform Switches, Nexus 5600 Platform Switches, Nexus 6000 Series Switches, Nexus 7000 Series Switches, Nexus 7700 Series Switches, Nexus 9000 Series Switches in standalone NX-OS mode, Nexus 9500 R-Series Line Cards and Fabric Modules, Unified Computing System Manager. Cisco Bug IDs: CSCvf15113, CSCvf15122, CSCvf15125, CSCvf15131, CSCvf15143, CSCvg04088.

Una vulnerabilidad en la interfaz de línea de comandos de NX-OS System Software podría permitir que un atacante local autenticado realice un ataque de inyección de comandos. Un atacante necesitaría credenciales de administrador válidas para explotar esta vulnerabilidad. La vulnerabilidad se debe a una validación de entradas insuficiente de los argumentos de comandos. Un atacante podría explotar esta vulnerabilidad inyectando argumentos de comando manipulados en un comando vulnerable de la interfaz de línea de comandos. El atacante podría utilizar un exploit para ejecutar comandos arbitrarios como root. Esta vulnerabilidad afecta a los siguientes productos que ejecutan Cisco NX-OS System Software: Multilayer Director Switches, Nexus 2000 Series Fabric Extenders, Nexus 3000 Series Switches, Nexus 3500 Platform Switches, Nexus 5000 Series Switches, Nexus 5500 Platform Switches, Nexus 5600 Platform Switches, Nexus 6000 Series Switches, Nexus 7000 Series Switches, Nexus 7700 Series Switches, Nexus 9000 Series Switches - Standalone, NX-OS mode, Nexus 9500 R-Series Line Cards and Fabric Modules y Unified Computing System Manager. Cisco Bug IDs: CSCvf15113, CSCvf15122, CSCvf15125, CSCvf15131, CSCvf15143, CSCvg04088.
