Recent Apache Web Server Vulnerabilities

Introduction

Greetings, dear readers! In the world of web servers, Apache is one of the most widely used web servers. It’s free, open-source, and provides excellent performance. Unfortunately, like any other web server, it is not immune to vulnerabilities. In this article, we’ll explore recent Apache web server vulnerabilities, their advantages and disadvantages, and what you can do to mitigate the risk.

Before we dive into the details, let’s define what a vulnerability is. A vulnerability is a weakness or flaw in a system, application, or network that could be exploited by threats to gain unauthorized access, disrupt operations, or steal sensitive information.

In recent years, Apache has been affected by various vulnerabilities. Some of these were minor bugs, while others were critical vulnerabilities that could seriously impact the security of your web server.

1. Recent Apache Web Server Vulnerabilities

One of the most critical vulnerabilities that Apache recently faced was the CVE-2021-41773. This vulnerability allowed an attacker to execute arbitrary code on the target server by exploiting a flaw in the mod_proxy module. This module is used to forward requests from an Apache web server to an application server.

Another significant vulnerability was the CVE-2020-11984, which affected Apache Tomcat, a popular web application server used with Apache web server. This vulnerability could allow an attacker to execute arbitrary code with the help of a malicious JSP file.

Other recent Apache web server vulnerabilities that were discovered include the CVE-2020-1938 and CVE-2019-10082. The former targeted the Apache JServ Protocol module, which allowed a remote attacker to execute code on the target server. The latter targeted the Apache HTTP Server’s mod_rewrite module, which allowed a malicious user to write arbitrary configurations and execute commands on the server.

2. Advantages and Disadvantages of Apache Web Server

Apache web server has several advantages. It’s free and open-source, meaning anyone can use it without cost. Additionally, it’s highly customizable and flexible, making it an excellent choice for both small and large websites. Apache also has a vast library of modules that can extend its functionality.

However, Apache also has some disadvantages. One of its main drawbacks is its performance. While Apache can handle a large number of concurrent connections, it’s not as efficient as some of its competitors, such as NGINX. Apache also requires more system resources to run effectively, which could impact the performance of your website.
