Apache 2.4.10 is an older version of the world's most popular web server software, released in 2014. While it powered thousands of websites, security researchers have identified 7 medium-severity vulnerabilities that could expose your site to attacks. If your website still runs this version, you're at significant risk of denial-of-service attacks, memory exploits, and potential code execution. This guide will help you identify whether you're vulnerable and show you exactly how to fix it.
The vulnerabilities in Apache 2.4.10 primarily affect different modules used for specific functions like proxying requests, handling CGI scripts, and compressing content. Each flaw could allow attackers to crash your server, steal sensitive data, or gain unauthorized access. With over 3,000 websites still using this outdated version, it's crucial to understand your exposure and take immediate action.
Apache is the software that runs your website's server. Think of it as the invisible worker that receives visitor requests and sends back your web pages. Apache 2.4.10 is a specific version released in 2014—it's now nearly a decade old and no longer receives security updates. When software is this old, hackers know exactly how to exploit its weaknesses.
Web servers are prime targets for cybercriminals because they control access to everything on your website. A vulnerable server can be hacked, defaced, or taken offline completely. The medium-severity vulnerabilities in Apache 2.4.10 are particularly dangerous because they're well-documented and relatively easy for attackers to exploit. These flaws affect popular features like proxy handling, CGI script processing, and content compression—features many websites rely on daily.
7 CVEs found. The most critical are explained below.
A flaw in Apache's status monitoring module could allow attackers to crash your server or potentially access sensitive information like passwords. This happens when someone sends a specially crafted request that confuses how the server manages its memory.
Impact: Your website could go offline, or an attacker could steal login credentials and passwords stored on your server.
↗ View on NVDWhen your server runs custom scripts (CGI programs), there's no safety timer to stop scripts that hang or get stuck. An attacker can intentionally submit requests that cause scripts to freeze indefinitely.
Impact: Your server's resources get consumed by stuck processes, causing your website to slow down dramatically or become unavailable to real visitors.
↗ View on NVDIf your server runs Apache on Windows, a bug in how the server accepts connections can cause it to slowly consume more and more memory with each request. Eventually, your server runs out of memory and crashes.
Impact: Your website gradually becomes slower and eventually stops responding as the server runs out of memory.
↗ View on NVDIf your website uses FastCGI applications with long response headers, a connected application server can send oversized headers that crash Apache. This doesn't require hacking into your server—the external application can cause the problem.
Impact: Your website crashes when certain applications send large response headers, causing downtime until the server is manually restarted.
↗ View on NVDIf you're using Apache as a reverse proxy (routing traffic to other servers), attackers can send specially crafted headers that crash your Apache processes. This is particularly dangerous if you're using Apache to manage traffic for multiple backend servers.
Impact: Your website and the services behind it become unavailable as the proxy crashes repeatedly.
↗ View on NVDIf your Apache is configured to automatically decompress incoming request data, attackers can send highly compressed files that expand to enormous sizes when decompressed. This wastes server resources rapidly.
Impact: Your server's CPU and memory get consumed by decompressing malicious data, causing your website to slow down or crash.
