Background

XPLG update release includes new features, optimizations and bug fixes. This release also addresses Apache Log4j moderate vulnerability (CVE-2021-44832) that was recently published.
Apache announced that Apache Log4j2 versions 2.0-beta7 through 2.17.0 (excluding security fix releases 2.3.2 and 2.12.4) are vulnerable to a remote code execution (RCE) attack where an attacker with permission to modify the logging configuration file can construct a malicious configuration using a JDBC Appender with a data source referencing a JNDI URI which can execute remote code.

The Apache Log4j 2 is an open-source Java package that allows developers to log activity within applications. More information is available here.

XPLG product suite impact

Recently we have published patch 8067 that migrates all used Log4j libraries within XPLG to Apache Log4j2 version 2.16.0. Following Apache later announcement, patch 8069 was released to migrate all used libraries to Apache Log4j2 version 2.17.0.
Following the latest Apache announcement, patch 8218 is now released to migrate all used libraries to Apache Log4j2 version 2.17.1 (latest patch includes all, if you haven’t updated yet please proceed only with the latest patch as detailed below).
