[ANN] Apache Struts 2.3.34 General Availability with Security Fixes Release
The Apache Struts group is pleased to announce that Struts 2.3.34 is
available as a “General Availability” release. The GA designation is
our highest quality grade.
This release addresses these potential security vulnerabilities:
- S2-050 A regular expression Denial of Service when using
URLValidator (similar to S2-044 & S2-047)
- S2-051 A remote attacker may create a DoS attack by sending crafted
xml request when using the Struts REST plugin
- S2-052 Possible Remote Code Execution attack when using the Struts
REST plugin with XStream handler to handle XML payloads
- S2-053 A possible Remote Code Execution attack when using an
unintentional expression in Freemarker tag instead of string literals
This release contains several minor improvements just to mention few of them:
- Struts2 JSON Plugin: Send Map with Strings as Key to JSON Action is
ignored, Numeric Keys will work and mapped
- Threads get blocked due to unnecessary synchronization in OgnlRuntime
- Upgrade to OGNL 3.0.21
- Upgrade to struts-master 11
- Improve RegEx used to validate URLs
More details in version notes
http://struts.apache.org/docs/version-notes-2334.html
All developers are strongly advised to perform this action.
The 2.3.x series of the Apache Struts framework has a minimum
requirement of the following specification versions: Servlet API 2.4,
JSP API 2.0, and Java 6.
Should any issues arise with your use of any version of the Struts
framework, please post your comments to the user list, and, if
appropriate, file a tracking ticket.
You can download this version from our download page.

It's exactly what JIRA produces
https://issues.apache.org/jira/secure/ReleaseNote.jspa?version=12341270&projectId=12311041
And I don't mind including such issues in the Version Notes as it may
help others identify their problems.

I'm curious if it's better and INFRA is able to not list "Not A Problem"
and "Not A Bug" issues in ANN and version notes. I'm not sure if it's a
good idea.

Nope, it's a different issue and mainly developers' fault. Upgrading
to 2.5.13 is only required when you are using the Struts 2 REST plugin
which isn't a case for all the apps.

Hi Łukasz,
Thanks for the notification. The upgrade advice on s2-053.html instructs
users to upgrade to Struts 2.5.*12* or 2.3.34 (including links to both
versions). I think you probably intended to write 2.5.*13* there?
Cheers,
Bas

Hi,
in this case it does not matter whether ${} is present as interator tag
uses expressions by default. There are other struts tags where it makes a
difference. I think param is among them.

Hello Lukasz,
I have a question:
For example in the doubleselect.ftl of the simple theme in line 102 I found
the following <@s.iterator value="${parameters.doubleList}">
Should this be changed to <@s.iterator value="parameters.doubleList"> like
in line 82 (Due to S2-053) ?
Kind regards Michael Hintenaus
