It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2023-140 advisory.

– 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. (CVE-2022-42252)

Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.Read More
