Apache Tomcat 9.0.40 to 9.0.53
Apache Tomcat 8.5.60 to 8.5.71

QID Detection Logic (Unauthenticated):
The QID checks for vulnerable version by sending a GET /QUALYS730242 HTTP/1.0 request which helps in retrieving the installed version of Apache Tomcat in the banner of the response.

Successful exploitation of the vulnerability can allow an attacker to trigger a DoS via an OutOfMemoryError.
