Apache Tomcat 9.0.0.M1 < 9.0.16

high Nessus Plugin ID 126312

Synopsis

The remote Apache Tomcat server is affected by a vulnerability

Description

The version of Tomcat installed on the remote host is prior to 9.0.16. It is, therefore, affected by a vulnerability as referenced in the fixed_in_apache_tomcat_9.0.16_security-9 advisory.

- The HTTP/2 implementation in Apache Tomcat 9.0.0.M1 to 9.0.14 and 8.5.0 to 8.5.37 accepted streams with excessive numbers of SETTINGS frames and also permitted clients to keep streams open without reading/writing request/response data. By keeping streams open for requests that utilised the Servlet API's blocking I/O, clients were able to cause server-side threads to block eventually leading to thread exhaustion and a DoS. (CVE-2019-0199)

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

Solution

Upgrade to Apache Tomcat version 9.0.16 or later.
