| Detailed Description |
The version of Tomcat installed on the remote host is prior to 9.0.20. It is, therefore, affected by a vulnerability as referenced in the fixed_in_apache_tomcat_9.0.20_security-9 advisory.
- The fix for CVE-2019-0199 was incomplete and did not address HTTP/2 connection window exhaustion on write. By not sending WINDOW_UPDATE messages for the connection window (stream 0) clients were able to cause server-side threads to block eventually leading to thread exhaustion and a DoS. (CVE-2019-10072)
