DNA and SD WAN Critical Security Vulnerability Notice

Cisco is urging enterprise administrators to install critical security updates. As always, a SMARTnet contract is not necessary to obtain fixed software for security vulnerabilities.

CVE-2019-1848 is a Cisco DNA Center authentication bypass vulnerability. Due to insufficient access restriction to the ports necessary for system operation, an attacker may reach internal services that are not hardened for external access. 9.3 (out of 10) CVSS score identifies this as a critical requirement to be addressed. A successful exploit could also let an unauthenticated attacker connect an unauthorized network device to the subnet designated for cluster services. Please ensure that you are running release 1.3 or newer. Fixed software is not available through Cisco’s software center. There is an “update” feature within the DNA Center that call for the fixed software.

CVE-2019-1625 is a Cisco SD-WAN privilege escalation vulnerability. The source is an insufficient authorization enforcement and could allow the attacker to make config changes to the system as the root user. CVSS score of 7.8. Impacted is any release of Cisco’s SD-WAN Solution prior to 18.3.6, 18.4.1, and 19.1.0. 18.4.1 is the minimum recommended image.

As Cisco continues to surge toward becoming a software company, please consider the potential impact that a major exploit could have on organizations if the market continues to adopt opening their networks to Cisco’s software development and new licensing model. Its not a matter of “if,” but rather “when?”
