Log4jAttackSurface VS Apache Log4j 2

Just look at the currently ongoing insanity that is the log4j exploit, and how one single exploit has lead to a generic attack that can impact tons of companies. Imagine if a state decided to use voting machines, and someone found this style of exploit in the system.

Last week (Dec 9th) a major vulnerability was discovered in an open source logging project for Java called log4j. The vulnerability called Log4Shell would allow anyone to remotely run arbitrary code if they sent a message in the right format to the server. This is one of the worst attacks your system can be susceptible to and if you are interested in the technical details of the problem, here is an overview. The attack surface of Log4Shell is staggering, Amazon, Apple, Google, and the Apache Server are affected; it can almost not get bigger than this. We will see the real fallout of Log4Shell in the next weeks and months as right now servers worldwide are being scanned and prodded for this vulnerability.

Companies should verify they are not running any exposed Log4j Java code.  Here is a list of impacted 3rd party software for your reference.  If you find a server at risk, there are three potential ways to fix it as follows.

Blender ist nicht betroffen, #42

It does and was also affected by log4j.

Thanks, sure it isn't complete but it does contain some scary and surprising (at least when first reading, of course the really aren't) things like: https://github.com/YfryTchsGD/Log4jAttackSurface/blob/master/pages/UniFi.md

Apparently there's proof Steam along with many others are vulnerable.

I don't think that's a good example. While Apache devs are volunteers and Microsoft devs are employees, they were criticized for their slow response time and seeming lack of urgency until it was far too late.

The official website. The vulnerability was introduced in 2.0-beta7 which was released in 2013.

However, there are many open source projects that are widely used but not well-known, including cURL, ImageMagick, MyCLI, Homebrew, Apache Log4j, and OpenSSL. This article will take a closer look at these unsung heroes of the open source world. I do not want to give them a business model or financial advice in this article. This largely depends on the author's personal experience and values. I just want to raise more awareness about these open source projects.

What you need is log4j-core, what you downloaded is some kind of connector between log4j and JUL. Tbh I don't know what JUL is, but that's not important. You can get log4j-core on from the official website - https://logging.apache.org/log4j/2.x/ or in maven repo. In case you're not using maven, I highly, highly recommend you using it for managing your dependencies.

> When it was first revealed in early December 2021, the Log4Shell bug was described as one of the most severe security vulnerabilities ever.

> The Apache Software Foundation, which maintains the open-source tool, quickly released a patch...

Apache horribly mismanaged this and did not release a patch until it was already widely known and being exploited in the wild. They also messed up and had to release several subsequent patches to actually fix the vulnerability.

Remember: this vulnerability was disclosed to them in November.

Think back to the Log4J event, were you affected? (https://github.com/apache/logging-log4j2)
