Tomcat Server Security Vulnerability

A recently revealed vulnerability in Apache Tomcat servers could leave millions of Web applications open to attack. The vulnerability, which is being described as a "serious issue," exists in the way that Tomcat servers process certain requests.

According to researchers at F5 Networks, the flaw could allow an attacker to execute arbitrary code on a Tomcat server. This, in turn, could give the attacker access to sensitive data or allow them to take control of the server.

The vulnerability was discovered by F5 Networks during a routine security audit. The company has since released a patch for the flaw, but it's likely that many organizations have yet to apply it. As such, it's plausible that this vulnerability could be exploited in the near future.

In order to protect your organization from this vulnerability, you should ensure that your Apache Tomcat servers are running the latest version of the software and that all security patches are applied. You should also deploy a suitable WAF (web application firewall) in front of your Tomcat servers to help mitigate any potential attacks.

In this article, we will show you how to install Tomcat 9 on Ubuntu 16.04.

Before starting with the installation, we assume that you have sudo privileges and a basic understanding of how to use the command line interface.

Tomcat is a popular Java Servlet Container that allows you to run Java web applications. It is an open source project released under the Apache License 2.0.

To install Tomcat 9 on Ubuntu 16.04, follow these steps:

1. First, add the Tomcat repository to your system by running the following command:

sudo add-apt-repository ppa:tomcat/9.0

1. Next, update your system and install Tomcat 9 by running the following command:

sudo apt update sudo apt install tomcat9 tomcat9-docs tomcat9-common libapache2-mod-jk If you are using a firewall, you may need to open port 8080 in order for Tomcat to work properly.

1. The final step is to configure Tomcat 9. You can do this by editing the /etc/tomcat/server.xml file with your favorite text editor. Some of the important settings that you may want to modify include: The port that Tomcat listens on (by default, it is 8080) The address that Tomcat listens on (by default, it is 0.0.0.0) Whether or not Tomcat should start automatically when your server starts up

2. That's it! You can now start using Tomcat 9 by running the following command: sudo service tomcat9 start

Setting up a Tomcat Web Server

This document will take you through the steps of installing and configuring a Tomcat web server.

Installing Tomcat

The first step is to download and install Tomcat. You can find the latest version of Tomcat at the following link:

https://tomcat.apache.org/download-90.cgi

Once you have downloaded the archive, extract it to a location of your choice. I recommend extracting it to a folder within your home directory, such as ~/tomcat .

Next, you need to set up your environment variables to point to the Tomcat installation. Open up your ~/.bashrc file in a text editor and add the following lines:

export CATALINA_HOME=~/tomcat export JRE_HOME=~/jre export PATH=$CATALINA_HOME/bin:$JRE_HOME/bin:$PATH

If you are using a different version of Java, be sure to adjust the JRE_HOME variable accordingly. Save and close the file.

To reload your environment variables, run the following command:

source ~/.bashrc

You can now start Tomcat by running the following command:

startup.sh

Tomcat should now be running and accessible at http://localhost:8080/.
