We are open-sourcing an open detection and scanning tool for discovering and fuzzing for Log4J RCE CVE-2021-44228 vulnerability. This shall be used by security teams to scan their infrastructure for Log4J RCE, and also test for WAF bypasses that can result in achiving code execution on the organization's environment.It supports DNS OOB callbacks out of the box, there is no need to setup a DNS callback server.UsageManagement Platform.
