QID 730648: Apache Tomcat request smuggling Vulnerability (CVE-2022-42252)

Apache Tomcat is an open source web server and servlet container developed by the Apache Software Foundation.

If Tomcat was configured to ignore invalid HTTP headers via setting rejectIllegalHeader to false (not 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.

Affected versions:
Apache Tomcat 10.1.0-M1 to 10.1.0

QID Detection Logic (Unauthenticated):
This QID sends a HTTP GET request to an invalid URL and based on the response confirms the vulnerable instance of Apache Tomcat running on the host.

Successful exploitation of this vulnerability could reveal sensitive information to an unauthorized attacker.

CVSS V3 rated as High - 7.5 severity.

CVSS V2 rated as Medium - 5.4 severity.

Customers are advised to upgrade Apache Tomcat to the new version to remediate this vulnerability. For more information please refer to Apache Tomcat Security Advisory.
