Amazon Linux AMI : tomcat7 (ALAS-2018-947)

medium Nessus Plugin ID 106692

Language:

Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

Incorrect documentation of CGI Servlet search algorithm may lead to misconfiguration :

As part of the fix for bug 61201, the documentation for Apache Tomcat included an updated description of the search algorithm used by the CGI Servlet to identify which script to execute. The update was not correct. As a result, some scripts may have failed to execute as expected and other scripts may have been executed unexpectedly. Note that the behaviour of the CGI servlet has remained unchanged in this regard. It is only the documentation of the behaviour that was wrong and has been corrected. (CVE-2017-15706)

Solution

Run 'yum update tomcat7' to update your system.
