[jira] [Comment Edited] (OFBIZ-12582) Prevent post-Auth vulnerability: FreeMarker Bypass

    [ https://issues.apache.org/jira/browse/OFBIZ-12582?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17496665#comment-17496665 ]

--------------------------------------------------------------------

Commit 16c8afe5d0c103aabd05b8237820a86eea761e1c in ofbiz-framework's branch refs/heads/release22.01 from Jacques Le Roux
[ https://gitbox.apache.org/repos/asf?p=ofbiz-framework.git;h=16c8afe ]

Fixed: Prevent post-Auth vulnerability: FreeMarker Bypass (OFBIZ-12582)

By inserting malicious content in the “Text” field from
“/content/control/updateLayoutSubContent” -> “Templates”, an attacker may
perform SSTI (Server-Side Template Injection) attacks, which can leverage
FreeMarker exposed objects to bypass restrictions and obtain RCE (Remote Code
Execution).

This fixes it by calling SecuredUpload::isValidText on the “Text” field content.
I'll check that there are no other attack opportunities...

Thanks:  Matei "Mal" Badanoiu for reporting this post-auth vulnerabily
