"The remote OT asset is affected by a vulnerability.");
  script_set_attribute(attribute:"description", value:
"A vulnerability in the CLI of Cisco NX-OS System Software could allow
an authenticated, local attacker to perform a command injection
attack. The vulnerability is due to insufficient input validation of
command arguments to the CLI parser. An attacker could exploit this
vulnerability by injecting crafted command arguments into a vulnerable
CLI command and gaining unauthorized access to the underlying
operating system of the device. An exploit could allow the attacker to
execute arbitrary commands at the user's privilege level. On products
that support multiple virtual device contexts (VDCs), this
vulnerability could allow an attacker to execute commands at the
user's privilege level outside the user's environment. 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 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. Cisco Bug IDs:
CSCve99902, CSCvf14879.
