Detailed Description The version of Tomcat installed on the remote host is prior to 10.0.27.

It is, therefore, affected by a vulnerability as referenced in the fixed_in_apache_tomcat_10.0.27_security-10 advisory.
- If Tomcat was configured to ignore invalid HTTP headers via setting rejectIllegalHeader to false (the default), Tomcat did not reject a request containing an invalid Content-Length header making a request smuggling attack possible if Tomcat was located behind a reverse proxy that also failed to reject the request with the invalid header. (CVE-2022-42252)
