Apache Tomcat 8.5.64 Denial of Service

high Web App Scanning Plugin ID 112905

Synopsis

Apache Tomcat 8.5.64 Denial of Service

Description

The version of Apache Tomcat installed on the remote host is 10.0.3 to 10.0.4, 9.0.44 or 8.5.64. It is, therefore, affected by a denial of service due to an error introduced as part of a change to improve error handling during non-blocking I/O.

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 8.5.65 or later.
