Code42 response to industry security incidents


When other security and technology companies disclose breaches and other security events, we often receive questions about whether those incidents affect Code42 products and services. This page provides information about if and how major, widely publicized breaches affect Code42 products and services.

Code42 constantly reviews and analyzes any security incidents that could impact our customers, products, and services. In addition to the list below, there may be other security incidents that we are reviewing. Because security incident details provide sensitive information that could be used maliciously, we are unable to publish information about every incident we review.

If a security event affects Code42 products and services, we contact affected customers and issue a security advisory.

If you have questions or concerns, contact our Customer Champions for support.

All deployments for Log4j 2.17

  • We will continue to apply additional patches for Log4j as they are released. Based on NIST guidelines as of December 20, 2021, Log4j 2.17 updates will be made as part of ongoing patch cycles in January 2022. Code42 will adjust planned upgrade cycles should requirements and guidelines change.

Additional context for Code42's approach to updating to Log4j 2.17

  • The vulnerability outlined in 2.16 references an attack with control over Thread Context Map data to cause a denial of service. 
    • Code42 products and services do not provide a way for an attacker to control Thread Context Map data.
    • Code42 products and services do not use any non-default logging patterns involving the Thread Context Map, which is required for exploitation.
  • Code42 has completed Red Team attacks and have engaged with security researchers via our bug bounty program to ensure we are not vulnerable to what is being described within Log4j version 2.16.

Cloud deployments for Log4j 2.16

December 17, 2021

4:45 pm ET

In line with guidance from CISA and NIST, Code42 is in the process of applying Log4j 2.16 to its products and services according to an accelerated timeline. Based on extensive testing, we do not believe that Code42 products and services are susceptible to risk presented by CVE- 2021-45046 once all currently available patches and mitigations as documented below have been implemented.

Current timeline for updating to Log4j 2.16:


On-premises deployments

Code42 products
Code42 released updates to the Code42 cloud infrastructure with an updated version of Log4j that mitigates the CVE-2021-44228 vulnerability.


Customers were made aware of the cloud infrastructure and Code42 app version 8.8.1 update via the Code42 Community and direct email.

Additional context for Code42 approach to updating to Log4j 2.16

  • We have completed Red Team attacks and have been engaged with security researchers via our Bug Bounty program to ensure we are not vulnerable to what is being described in CVE-2021-45046.
  • Our agent and cloud services have a common lib-logging library which wraps our usage of Log4j. This constrains our usage down a standard path (default configuration) that does not utilize any of the vulnerable methods (ThreadContexMap, Logger.printF, or the other formattable stringBuilder) found to date.
  • We were previously and are currently running a JVM version of 11.0.1 or higher which mitigates against many of the RCE known exploits.
  • We have completed a scan of our code to ensure it does not use non-standard configurations which are outlined as part of the attack path for this vulnerability.
  • Many of the reported “bypass” attempts require either other known vulnerable dependencies be loaded or opt-in to known vulnerable configurations. We have confirmed our products are not vulnerable to the “bypass” exploits reported to date.


Updated December 16, 2021 at 1:10 pm ET with additional details:

After Log4j version 2.15 was released and applied to Code42 products, a newer Log4j version (2.16) was released that remediates additional vulnerabilities. We have assessed version 2.16 and determined it does not remediate vulnerabilities in Code42 products. Therefore, we will not be doing an emergency patch to apply Log4j 2.16 because version 2.15 addresses the critical vulnerability. Version 2.16 addresses a very specific edge case related to a logging configuration that we do not use in our products.

As always, we will be monitoring for updated versions and apply those versions as necessary.

Code42 services
Code42 User Directory Sync uses a Log4j version that is vulnerable to CVE 2021-44228; most Code42 customers do not have access to or use this service. If configured according to Code42 guidelines, this service is not accessible to the public internet and therefore has mitigation in place. If you are concerned about this vulnerability in your environment, please contact support at for further information. In the coming weeks, Code42 will provide an update to Code42 User Directory Sync that will use a Log4j version that is not vulnerable to CVE 2021-44228.

(original message)

Code42 product 
Code42 does use Java within Code42 products, but current releases of all affected services and agents leverage a JVM (Java virtual machine) version higher than 11.0.1, which prevents the remote code execution vulnerability from execution. As a further point of mitigation, Code42 will update to the latest patched version of Log4j as part of future product releases.

In addition, Code42 does not leverage Apache Tomcat or Apache Struts components as part of our products.


Code42 internal corporate applications 
Code42 also leverages Java on specific internal corporate applications. These applications are currently being reviewed for potential impact and are scheduled for patching.
