Description

If Apache Tomcat 8.5.0 to 8.5.82, 9.0.0-M1 to 9.0.67, 10.0.0-M1 to 10.0.26 or 10.1.0-M1 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.

Affected configurations

• apache tomcat (>= 8.5.0 < 8.5.83) • apache tomcat (>= 9.0.0 < 9.0.68) • apache tomcat (>= 10.0.0 < 10.0.27) • apache tomcat (>= 10.1.0 < 10.1.1)
