Description

Log4jPatcher

A Java Agent based mitigation for Log4j2 JNDI exploits.

This agent employs 2 patches:

Disabling all Lookup conversions (on supported Log4j versions) in org.apache.logging.log4j.core.pattern.MessagePatternConverter by setting noLookups to true in the constructor.
Disabling the org.apache.logging.log4j.core.lookup.JndiLookup class by just returning null in its lookup function.

Add -javaagent:Log4jPatcher.jar as a JVM argument.
