Connectwise: >> Automate Security Vulnerabilities
The ConnectWise Automate Agent does not fully verify the authenticity of files downloaded from the server, such as updates, dependencies, and integrations. This creates a risk where an on-path attacker could perform a man-in-the-middle attack and substitute malicious files for legitimate ones by impersonating a legitimate server. This risk is mitigated when HTTPS is enforced and is related to CVE-2025-11492.

In the ConnectWise Automate Agent, communications could be configured to use HTTP instead of HTTPS. In such cases, an on-path threat actor with a man-in-the-middle network position could intercept, modify, or replay agent-server traffic. Additionally, the encryption method used to obfuscate some communications over the HTTP channel is updated in the Automate 2025.9 patch to enforce HTTPS for all agent communications.

Connectwise Automate 2022.11 is vulnerable to Cleartext authentication. Authentication is being done via HTTP (cleartext) with SSL disabled. OTE: the vendor's position is that, by design, this is controlled by a configuration option in which a customer can choose to use HTTP (rather than HTTPS) during troubleshooting.
