CVE-2019-17571 Apache Log4j Vulnerability

Severity: Medium2020-01-23

Security Advisories


On December 19, 2019, Apache Software Foundation (ASF) officially released a security advisory, announcing that Apache Log4j has a deserialization issue that could cause remote code execution (CVE-2019-17571). Log4j is a Java-based open-source logging tool that includes a SocketServer class which can easily accept serialized log events and deserialize them without authentication. With the aid of deserialization tools, an attacker could use this class to remotely execute arbitrary code. This affects Log4j versions up to 1.2 up to 1.2.17. A similar flaw found in Log4j 2.x has been assigned CVE-2017-5645.

Multiple Oxygen XML products incorporate Apache Log4j as third party library. This advisory was opened to address the potential impact on this third party library vulnerability.
