webtools/control/ProgramExport (OFBIZ-12571)

commit 9e5fe107368247bb9df81fa5b2900e489a515ddd
Author: Jacques Le Roux <jacques.le.r...@les7arts.com>

Fixed: Groovy denied list bypass causes post-auth RCE from
webtools/control/ProgramExport (OFBIZ-12571)
The 1st issue was due to use of processbuilder token. It has been added to
deniedWebShellTokens in security.properties by f2cf262 commit for OFBIZ
11948
The tokens function (for js) and class have been added since while browsing
https://github.com/tennc/webshell
As mention the related deniedWebShellTokens TODO comment: "TODO.... to be
continued
with known webshell contents... a complete allow list is impossible
anyway...
So, later a deeper review of Groovy sandbox possibilities will be done..
Thanks: Y4er for report
