What it detects

This rule detects HTTP requests carrying an OGNL injection payload in the Content-Type header. The NKAbuse intrusion begins by exploiting the Struts2 vulnerability CVE-2017-5638, which smuggles an OGNL expression through a malformed Content-Type to run commands on the server, so this header content indicates attempted remote code execution against a public-facing web application.
