What are the security vulnerabilities in NGINX 1.18 0?

A vulnerability was found in nginx up to 1.18. 0 (Web Server) and classified as critical. Affected by this issue is an unknown functionality. The manipulation as part of a HTTP Request leads to a request smuggling vulnerability.

Is NGINX affected by Log4j vulnerability?

(NGINX itself is written in C and does not use Java or any Java‑based libraries so was unaffected by the Log4j vulnerabilities…)

Is NGINX affected by Log4j?

NGINX itself is not vulnerable to this exploit, because it is written in C and does not use Java or any Java‑based libraries.

Can NGINX be hacked?

NGINX has always been a target for hackers/bug bounty hunters due to a lot of misconfigurations in it, and as a security researcher/bug bounty hunter, hacking a web server always fascinates us.

Is NGINX 1.20 stable?

Source Releases

There are currently two versions of NGINX available: stable (1.20.x) , mainline (1.21.x) . The mainline branch gets new features and bugfixes sooner but might introduce new bugs as well. Critical bugfixes are backported to the stable branch.

Is NGINX server secure?

nginx is built to be stable and secure, but it will only be as secure as the user who configures it. Once nginx is built and installed, configuring the server to be as minimal as possible is important.

Is Log4j 1.2 vulnerable?

Details of CVE-2021-4104

JMSAppender, in log4j 1.2 version, is vulnerable to deserialization of untrusted data if the attacker has the 'write' permissions to the log4j configuration.

Is Log4j 1.2 affected by vulnerability?

Included in Log4j 1.2 is a SocketServer class that is vulnerable to deserialization of untrusted data which can be exploited to remotely execute arbitrary code when combined with a deserialization gadget when listening to untrusted network traffic for log data.

Is TLS 1.3 vulnerability?

This vulnerability allows a remote unauthenticated attacker to cause a denial-of-service (DoS) on the BIG-IP system. There is no control plane exposure; this is a data plane issue only. Note: TLS 1.3 is disabled by default. This vulnerability affects only configurations where TLS 1.3 has been explicitly enabled.

Is NGINX more secure than Apache?

Since NGINX is designed to be efficient, it doesn't need to search for . htaccess files and interpret them, making it able to serve a request faster than Apache. NGINX keeps your server secure by not allowing additional configuration since only someone with root permission can alter your server and site's settings.

Does NGINX conflict with Apache?

Conclusion. The most important thing we take from this simple configuration is that Apache and Nginx can and do work together. A problem may arise when they both listen to the same ports. By giving them different ports to listen to, your system functionality is assured.

What is the stable version of NGINX?

Source Releases

There are currently two versions of NGINX available: stable (1.20. x) , mainline (1.21. x) . The mainline branch gets new features and bugfixes sooner but might introduce new bugs as well.

What versions of log4j are vulnerable?

Apache Log4j2 versions from 2.0-beta7 to 2.17. 0 (excluding security fix releases 2.3. 2 and 2.12. 4) are vulnerable to a remote code execution attack.

What versions of Exchange are vulnerable to ProxyShell?

What is ProxyShell? As mentioned above, ProxyShell are three different CVEs, affecting Microsoft Exchange servers versions: 2013, 2016, and 2019, that can be chained together to perform a Remote Code Execution attack from an unauthenticated user.

What versions of Polkit are vulnerable?

Any system that has polkit version 0.113 (or later) installed is vulnerable.

Is NGINX still faster than Apache?

Performance – NGINX performs faster than Apache in providing static content, but it needs help from another piece of software to process dynamic content requests. On the other hand, Apache can handle dynamic content internally. Directory-level configuration – Apache comes with .

Why is NGINX so fast?

NGINX handles requests asynchronously with event-driven architecture. NGINX was made to utilize a non-blocking, event-driven handling algorithm, so it can accommodate potentially thousands of connection requests at the same time, in one processing thread. It can also work quickly regardless of resources being minimal.

Is NGINX better than Apache?

Is Apache Better than NGINX? In terms of performance, NGINX is much better than Apache. NGINX performs 2.5 times faster than Apache — and consumes less memory as well.

What is the safest version of Log4j?

Though the Apache team has removed the vulnerability, and for additional security, also disabled the remote lookup facility from Log4j v 2.16. 0 onwards, the safest versions are now Log4j 2.17.
