Cisco Prime Data Center Network Manager 10.1.x < 10.2.1 Multiple Vulnerabilities (remote check)

critical Nessus Plugin ID 100993

Synopsis

A network management system running on the remote host is affected by multiple vulnerabilities.

Description

According to its self-reported version number, the Cisco Prime Data Center Network Manager (DCNM) installed on the remote host is 10.1.x prior to 10.2.1. It is, therefore, affected by multiple vulnerabilities :

- A remote code execution vulnerability exists in the role-based access control (RBAC) functionality due to a lack of authentication and authorization mechanisms for a debugging tool. An unauthenticated, remote attacker can exploit this to execute arbitrary code with root privileges. (CVE-2017-6639)

- A flaw exists due to the presence of a default user account with a static password that is not automatically removed post-installation. An unauthenticated, remote attacker can exploit this to login and gain root or system-level privileges. (CVE-2017-6640)

Note that this plugin determines if DCNM is vulnerable by checking the version number displayed in the web interface. However, the web interface is not available in older versions of DCNM.

Solution

Upgrade to Cisco Prime Data Center Network Manager version 10.2.1 or later.
