The Apache Log4j team developed Log4j 2 [7] in response to the problems of Log4j 1.2, 1.3, java.util.logging and Logback, addressing issues which appeared in those frameworks. [8] In addition, Log4j 2 offered a plugin architecture which makes it more extensible than its predecessor.
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.
JCL and Log4j are very common simply because they have been around for so long and were the only choices for a long time. The flexibility of slf4j (using Logback underneath) has made it a popular choice. SLF4J is a set of logging wrappers (or shims) that allow it to imitate any of the other frameworks.
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.
