Update Since Adobe has released an update for 2018, and 2021 which bring the log4j version to 2.16.0, I still don't think it is a bad idea to add the JVM mitigation, incase there are any third party libraries on your server now or in the future.ĬoldFusion 2016, update 17 appears to ship with log4j-1.2.17, see info below about log4j 1.x versions.ĭiscussion about this issue can be found on Adobe Forums.įrom what I have seen, lucee ships with log4j 1.2.x which is not listed as an affected version for CVE-2021-44228. Then if you are on CF2018/2021 follow their KB article to update log4j to version 2.17.0 (or 2.17.1) Update Adobe released ColdFusion 2021 update 4, ColdFusion 2018 update 14 which update log4j version to 2.17.2 My suggestion for people using ColdFusion would be to update to the latest patched version of ColdFusion, and then add the JVM arg -Dlog4j2.formatMsgNoLookups=true to the java.args line in your jvm.config file. Some versions early versions of ColdFusion 2018 include a version of log4j before 2.10.0 and greater than 2.0 which means that JVM arg mitigation doesn't work, so you would need to update to the latest version first. Previous advice from Adobe is no longer relevant after update 4/14 KB article 1, KB Article 2

To address CVE-2021-45105 and CVE-2021-44832 apply ColdFusion 2018 update 14 or ColdFusion 2021 Update 4 (which updates log4j version to 2.17.2). Adobe has published a KB article on, and on released ColdFusion 2021 Update 3, and ColdFusion 2018 Update 13 to address CVE-2021-44228 and CVE-2021-45046 by updating log4j to version 2.16.0. I notified the Adobe Product Security Incident Response Team (PSIRT) early Friday () morning of the issue. FuseGuard a WAF written in CFML has added a Log4ShellFilter in version 3.4.0Īdobe ColdFusion 20 include potentially vulnerable versions of log4j2. Many if not all WAF patterns could be evaded, but they can still block many attempts (defense in depth). However you should never treat a WAF as a 100% solution.

Many Web Application Firewalls (WAF) provide detection / blocking of Log4Shell attack patterns.

If you cannot use the jvm arg because you have log4j2 2.0 - 2.10.0 and for some reason cannot update to version 2.17.0 then it should be safe remove the offending JndiLookup.class class file from the jar.

You may still have DOS issues to consider with this approach. This could also be done at the jvm level using a java security policy or sandbox security in ColdFusion. This might be tricky depending on your requirements, but if the server cannot make a network request to the internet, this has a big impact on the severity of this.

Use your network firewall to ensure that no egress internet traffic leaves the server.

All of the above require restarting the java process (restart ColdFusion or Lucee).Ī few additional mitigations that you can consider:.

According to Microsoft's Response to this issue, you can set an environment variable instead of the JVM argument: LOG4J_FORMAT_MSG_NO_LOOKUPS=true - incomplete for CVE-2021-45046, CVE-2021-45105, CVE-2021-44832.

Add JVM arg: -Dlog4j2.formatMsgNoLookups=true (only works on log4j 2.10.0 and up).

Here's a list of possible mitigations, initially sourced from LunaSec's blog: 2.17.1 was released to address this issue. Log4j versions 2.17.0 and below are vulnerable to a RCE when the attacker can modify the log4j configuration. Fixed in 2.16.0Ī Denial of Service (DOS) issue in 2.16.0 and below, fixed in 2.17.0 Version 2.16.0 was released.Īnother issue was found in 2.15.0, a more serious / critical RCE. It appears that the fix in 2.15.0 and the JVM mitigation was incomplete.

Here's the jira issue for when the JNDI lookup feature was added in 2.0-beta9: LOG4J2-313 Versions Affected: all versions from 2.0-beta9 to 2.14.1. What versions of log4j are vulnerable to CVE-2021-44228? Lucee has released version 5.3.9.133 with Log4j 2.17.2, earlier versions used log4j 1.x.

TLDR: Adobe ColdFusion users should upgrade to either ColdFusion 2018 update 14 or ColdFusion 2021 Update 4 (both now use log4j version 2.17.2). Putting together some info to help sort this issue out as it pertains to ColdFusion and Lucee users. It is included in both Adobe ColdFusion and Lucee for example. There is a critical security vulnerability ( CVE-2021-44228 aka Log4Shell) in the java library log4j which is a popular logging library for java applications.
