What it detects

This rule flags HTTP requests to WebLogic endpoints containing URL-encoded path traversal sequences targeting the console image and CSS paths. Attackers may use these crafted requests to reach unauthorized resources or trigger vulnerable behavior associated with CVE-2020-14882 attempts. Detection relies on webserver telemetry that records the full URI query string so the encoded traversal patterns can be matched.
