"A vulnerability in the network-operator user role implementation for
Cisco NX-OS System Software could allow an authenticated, local
attacker to improperly delete valid user accounts. The network-
operator role should not be able to delete other configured users on
the device. The vulnerability is due to a lack of proper role-based
access control (RBAC) checks for the actions that a user with the
network-operator role is allowed to perform. An attacker could exploit
this vulnerability by authenticating to the device with user
credentials that give that user the network-operator role. Successful
exploitation could allow the attacker to impact the integrity of the
device by deleting configured user credentials. The attacker would
need valid user credentials for the device. This vulnerability affects
the following Cisco products running Cisco NX-OS System Software:
Nexus 3000 Series Switches, Nexus 3600 Platform Switches, Nexus 9000
Series Switches in standalone NX-OS mode, Nexus 9500 R-Series Line
Cards and Fabric Modules. Cisco Bug IDs: CSCvg21120.

This plugin only works with Tenable.ot.
