Apache Log4j 2 is the successor of Log4j 1 which was released as GA version in July 2015. The framework was rewritten from scratch and has been inspired by existing logging solutions, including Log4j 1 and java.util.logging.
Log4j is an under-the-radar software tool that is quietly distributed into the back-end of countless technology products, so companies have to do extensive audits to locate each and every instance ...
Log4Shell (CVE-2021-44228) is a zero-day vulnerability reported in November 2021 in Log4j, a popular Java logging framework, involving arbitrary code execution. [2] [3] The vulnerability had existed unnoticed since 2013 and was privately disclosed to the Apache Software Foundation, of which Log4j is a project, by Chen Zhaojun of Alibaba Cloud's security team on 24 November 2021.
The danger of Log4j. The Log4j vulnerability is dangerous for two reasons: how widely used the software is, and how attackers can take advantage of the flaw.
Log4j 2 provides both an API and an implementation. The API can be routed to other logging implementations equivalent to how SLF4J works. Unlike SLF4J, the Log4j 2 API logs Message [2] objects instead of Strings for extra flexibility and also supports Java Lambda expressions. [3] JCL isn't really a logging framework, but a wrapper for one.

Simple Logging Facade for Java (SLF4J) provides a Java logging API by means of a simple facade pattern.The underlying logging backend is determined at runtime by adding the desired binding to the classpath and may be the standard Sun Java logging package java.util.logging, [2] Log4j, Reload4j, Logback [3] or tinylog.
Shellshock, also known as Bashdoor, [1] is a family of security bugs [2] in the Unix Bash shell, the first of which was disclosed on 24 September 2014.Shellshock could enable an attacker to cause Bash to execute arbitrary commands and gain unauthorized access [3] to many Internet-facing services, such as web servers, that use Bash to process requests.
