CVE-2026-6066 describes a vulnerability in the ConnectWise Automate Solution Center where specific client-to-server communications may occur without transport-layer encryption. An attacker positioned on the network could intercept sensitive data transmitted in cleartext. This vulnerability was disclosed on April 20, 2026, and affects ConnectWise Automate versions prior to 2026.4. Successful exploitation allows an attacker to potentially gain access to credentials, configuration details, and other sensitive information related to the managed clients. The vulnerability has been resolved in Automate 2026.4 by enforcing secure communication for affected Solution Center connections.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAttacker gains network access to a ConnectWise Automate deployment.\u003c/li\u003e\n\u003cli\u003eAttacker passively monitors network traffic for communications between Automate clients and the Solution Center.\u003c/li\u003e\n\u003cli\u003eAttacker identifies vulnerable client-to-server communications occurring without transport-layer encryption.\u003c/li\u003e\n\u003cli\u003eAttacker intercepts the cleartext network traffic using a packet capture tool such as Wireshark or tcpdump.\u003c/li\u003e\n\u003cli\u003eAttacker analyzes the intercepted traffic to identify sensitive information such as credentials or configuration data.\u003c/li\u003e\n\u003cli\u003eAttacker uses the acquired credentials to gain unauthorized access to managed systems or customer environments.\u003c/li\u003e\n\u003cli\u003eAttacker leverages compromised systems for lateral movement within the network.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of CVE-2026-6066 can lead to the compromise of ConnectWise Automate deployments, potentially affecting hundreds or thousands of MSP clients.
