Original Bulletin: 
   https://lists.apache.org/thread.html/65ddd346447e388c9fa7f50eb65b13323a347fb265c25345747e83a7@%3Cannouncements.struts.apache.org%3E

- --------------------------BEGIN INCLUDED TEXT--------------------

The Apache Struts Team recommends to immediately upgrade your Struts 2.3.36
based projects to use the latest released version of Commons
FileUpload library, which is currently 1.3.1. This is necessary to
prevent your publicly accessible web site from being exposed to
possible DoS attacks [1] [2].

Your project is affected if it uses the built-in file upload mechanism
of Struts 2, which defaults to the use of commons-fileupload. The
updated commons-fileupload library is a drop-in replacement for the
vulnerable version. Deployed applications can be hardened by replacing
the commons-fileupload jar file in WEB-INF/lib with the fixed jar. For
Maven based Struts 2 projects, the following dependency needs to be
added:
<dependency>
    <groupId>commons-fileupload</groupId>
    <artifactId>commons-fileupload</artifactId>
    <version>1.3.1</version>
</dependency>

I meant commons-fileupload version 1.3.3, sorry for that.


Kind regards
