---------------------------------------------------------
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: Mal Aware <aware...@gmail.com> for reporting this post-auth vulnerabily
