What it detects

This rule flags unauthenticated HTTP GET requests to Ruckus Wireless Admin login-related endpoints that include credential fields and embedded shell/substitution patterns. The matching query parameters suggest an attempt to inject or execute code through crafted input, consistent with exploitation attempts. It relies on webserver telemetry capturing HTTP method and full query strings, including URL-encoded characters.
