What it detects

This rule detects web requests to the ScreenConnect SetupWizard.aspx endpoint followed by an extra trailing path segment, the request shape that triggers the CVE-2024-1709 authentication bypass. Huntress observed this pattern used to reach the setup wizard on already configured servers and create attacker administrator accounts. A trailing path after SetupWizard.aspx is not produced by normal setup flows and indicates exploitation.
