ConnectWise Automate Flaw Exposes Client Traffic to Interception
The National Vulnerability Database has detailed CVE-2026-6066, a high-severity vulnerability impacting ConnectWise Automate. The issue stems from client-to-server communications within the Solution Center that could occur without transport-layer encryption. This oversight creates an opening for network-based attackers to intercept sensitive traffic in affected Automate deployments.
ConnectWise has addressed this by releasing Automate 2026.4, which enforces secure communication for these connections. However, the existence of such a flaw highlights the ongoing need for vigilance in securing remote management and monitoring (RMM) tools, which are prime targets for attackers seeking broad access.
Defenders must ensure all ConnectWise Automate instances are updated to version 2026.4 or later. Furthermore, organizations should review network segmentation and traffic monitoring to detect any anomalous activity related to RMM tool communications, as compromised RMMs can grant attackers significant lateral movement capabilities.
What This Means For You
- If your organization uses ConnectWise Automate, immediately verify that you are running version 2026.4 or higher to mitigate the risk of traffic interception. Audit your network for any signs of unauthorized Solution Center traffic.
