Log4j is a popular logging component used within most of Java software packages. This current security exposure poses a credible risk to many organizations, as certain exploit code may offer the opportunity for unwanted Remote Code Execution (RCE).

What is the Apache Log4j Security Exposure?

This security bug is widely referred to as “Log4shell”. It was identified on December 9th and categorized as a severe zero-day vulnerability (a documented security bug without a patch) in Log4j. The issue is caused by a weakness in the Log4j library, which allows an unsolicited action on the system. Apache has given the denotation CVE-2021-44228 to this security bug, referring to an “unauthenticated Remote Code Execution” (RCE).

A second vulnerability in Apache Log4j was identified on December 14th. This is tracked as ‘CVE-2021-45046’. This new issue has already been patched in the recommended update Log4j 2.17.1.

Your IT team must determine if you have any direct or indirect dependencies to Log4j versions between 2.0-beta9 and 2.17.0.

How Can You Mitigate This Issue?

If you are using an exploited version of Log4j (2.0-beta9 to 2.17.0) and using a JAVA version earlier than version 11:
