All Versa SD-WAN customers who access Versa Director without the benefit of implemented system hardening and firewall guidelines are under severe threat from this vulnerability, as threat actors can compromise their network and its resources by evading entry controls using bypass authentication.

This particular vulnerability is still considered “High” in the Common Vulnerability Scoring System (CVSS) because it is relatively likely to result in remote code execution and lateral movement within the affected networks.

Consequently, the CISA has covered this vulnerability in its list of practicing denial-of-service attacks.

The targeting focuses on less hardened and consequently more vulnerable Versa SD-WAN systems, compromising Features such as Network Segmentation, Traffic Routing, and Security Policies, among others.

Affected organizations are warned to use the available security patches, perform additional hardening as recommended by Versa, and consider using other network segmentation and monitoring systems to prevent and detect exploitation attempts.
