Summary
Apache Tomcat request smuggling via malformed content-length
Details

If Apache Tomcat 8.5.0 to 8.5.82, 9.0.0 to 9.0.67, 10.0.0 to 10.0.26 or 10.1.0 to 10.1.0 was configured to ignore invalid HTTP headers via setting rejectIllegalHeader to false (the default for 8.5.x only), 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.
