The vulnerability is due to insufficient restrictions in the patch installation process. An attacker could exploit this vulnerability by installing a crafted patch image on an affected device. The vulnerable operation occurs prior to patch activation. An exploit could allow the attacker to write arbitrary files on an affected system as root. The attacker would need valid administrator credentials to perform this exploit. 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.
