Ecosystem Agent version 4 < 4.5.1.2597 and Ecosystem Agent version 5 < 5.1.4.2473 did not properly validate SSL/TLS certificates, which could allow a malicious actor to perform a Man-in-the-Middle and intercept traffic between the agent and N-able servers from a privileged network position.
The product does not validate, or incorrectly validates, a certificate.
