Commit f65410ba1d6b13ea5edfb07aa43b65a8f296cb89 in ofbiz-framework's branch
refs/heads/release18.12 from Jacques Le Roux
[ https://gitbox.apache.org/repos/asf?p=ofbiz-framework.git;h=f65410b ]
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
Conflicts handled by hand in ContentManagementServices.java
