QID 730042: Apache Tomcat Duplicate Request Headers Vulnerabilities

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

Affected Versions:
Apache Tomcat 8.5.0 to 8.5.61

QID Detection Logic (Unauthenticated):
The QID checks for vulnerable version by sending a GET /QUALYS13827 HTTP/1.0 request which helps in retrieving the installed version of Apache Tomcat in the banner of the response.

Apache Tomcat could duplicate request headers and a limited amount of request body from one request to another meaning user A and user B could both see the results of user A's request.

CVSS V3 rated as High - 7.5 severity.
