Synopsis
Apache Log4j Remote Code Execution (Log4Shell)Description
Apache Log4j is an open source Java-based logging framework leveraged within numerous Java applications. Apache Log4j versions 2.0-beta9 to 2.15.0 suffer from insufficient protections on message lookup substitutions when dealing with user controlled input. By crafting a malicious string, an attacker could leverage this issue to achieve a remote code execution on the Log4j instance used by the target application.Solution
Upgrade to version 2.16.0 or later.See Also
