"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 during the installation of a software patch. An attacker
could exploit this vulnerability by installing a crafted patch image
with the vulnerable operation occurring prior to patch activation. An
exploit could allow the attacker to execute arbitrary commands on an
affected system as root. This vulnerability affects the following
products running Cisco NX-OS System Software: Multilayer Director
Switches, Nexus 2000 Series Fabric Extenders, Nexus 5000 Series
Switches, Nexus 5500 Platform Switches, Nexus 5600 Platform Switches,
Nexus 6000 Series Switches, Nexus 7000 Series Switches, Nexus 7700
Series Switches, Unified Computing System Manager. Cisco Bug IDs:
CSCvf23735, CSCvg04072.
