Dear customers,

We have been told that Apache is working to fix a new vulnerability identified by security researchers that supposedly allows remote command execution again. The vulnerability would affect version 2.17.0, which includes a patch for a similar vulnerability of equal severity. We recommend that customers using the library monitor the official Log4J page for more details https://logging.apache.org/log4j/2.x/security.html and apply patches as they become available.

As soon as possible, when new information becomes available, new checks will be added to Syhunt, allowing Syhunt tools to detect this new variant.
