webtools/control/ProgramExport (OFBIZ-12571)
28092f2 is described below
commit 28092f2a7568634c1dd9c6c70f3656f13ca7a431
Author: Jacques Le Roux <jacques.le.r...@les7arts.com>
AuthorDate: Fri Feb 11 10:52:43 2022 +0100
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
