CVE-2023-23127Network attack vector

Credential exposure via configurable HTTP login

Published Feb 1, 2023 · Updated Aug 2, 2024

Missing transport protection on the ConnectWise Control 22.8.10013.8329 login page allows man-in-the-middle attackers to read credentials. The login response omits the Strict-Transport-Security header, so a browser can use HTTP and send login data without transport encryption. Exposure requires an instance configured to permit HTTP and man-in-the-middle attackers able to intercept login traffic; ConnectWise disputes the issue because HTTP is an intentional troubleshooting option.
