Introduction

EVS is actively responding to the reported vulnerability in the Apache Log4j 2 Java library dubbed Log4Shell. We are currently conducting a product-by-product analysis to determine if any are potentially impacted by the vulnerability. This is an ongoing investigation, so please check this bulletin page frequently for updates.

Description

Log4j is an open-source Java logging library that is widely used in many applications and is present as a dependency in many services. This includes enterprise applications and numerous cloud services.

This vulnerability allows for unauthenticated remote code execution using the flow explained in the following article: https://www.lunasec.io/docs/blog/log4j-zero-day/

Public Workaround

It is important to note that as part of the exploitation of this vulnerability, the vulnerable server must make an outbound request to the attacker owned server. Limiting outbound internet connectivity from web servers would prevent the full exploit chain.

Set to the JVM args log4j2.formatMsgNoLookups set to True in case not patched.
(see: https://logging.apache.org/log4j/2.x/manual/configuration.html)
