A vulnerability in X.509 certificate authentication allows an attacker to bypass security checks in specific configurations.
Apache 2.4.18 is severely outdated. If you are running this version, you should immediately Update Apache to the latest stable release (currently 2.4.64 or newer) to patch these critical flaws. Apache HTTP Server 2.4 vulnerabilities
Apache HTTP Server is one of the most widely used web servers on the internet, powering over 40% of all websites. However, in 2016, a critical vulnerability was discovered in Apache 2.4.18, putting countless web servers at risk of exploitation. In this feature, we'll explore the Apache 2.4.18 vulnerability, its impact, and the measures you can take to protect your web server.
The exploit takes advantage of a weakness in the Apache HTTP Server's handling of HTTP requests. Specifically, an attacker can send a crafted HTTP request with a specific type of payload, which can lead to a buffer overflow in the server's memory. This buffer overflow can be exploited to execute arbitrary code on the server, giving the attacker full control over the system.
By adhering to these recommendations, organizations can protect themselves against known vulnerabilities like the Apache 2.4.18 exploit and emerging threats in the cybersecurity landscape.
Using fuzzed network input, the HTTP/2 session handling can be forced to read memory after it has been freed during connection shutdown, leading to potential instability.
Several issues can be exploited to crash or hang an Apache 2.4.18 server:
