CVE-2018-0092
https://notcve.org/view.php?id=CVE-2018-0092
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. • http://www.securityfocus.com/bid/102750 http://www.securitytracker.com/id/1040248 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180117-nxos1 • CWE-264: Permissions, Privileges, and Access Controls CWE-862: Missing Authorization •
