Apache Tomcat 9.0.40 < 9.0.54 Denial of Service

high Web App Scanning Plugin ID 113019

Synopsis

Apache Tomcat 9.0.40 < 9.0.54 Denial of Service

Description

The version of Apache Tomcat installed on the remote host is 10.1.0-M1 to 10.1.0-M5, 10.0.0-M10 to 10.0.11, 9.0.40 to 9.0.53 or 8.5.60 to 8.5.71. It is, therefore, affected by a denial of service. The object introduced to collect metrics for HTTP upgrade connections was not released for WebSocket connections once the WebSocket connection was closed. This created a memory leak that, over time, could lead to a denial of service via an OutOfMemoryError.

Note that the scanner has not attempted to exploit these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Apache Tomcat version 9.0.54 or later.
