severity: critical

|
description: |
|
|
Apache OFBiz is affected by a remote code execution vulnerability in the bundled Apache Log4j logging library. Apache Log4j is vulnerable due to insufficient protections on message lookup substitutions when dealing with user controlled input. A remote, unauthenticated attacker can exploit this, via a web request, to execute arbitrary code with the permission level of the running Java process.
