27 March 2018 - A crafted XML request can be used to perform a DoS attack when using the Struts REST plugin

The Apache Security Struts Team recommends to immediately upgrade your Struts 2 based projects to use the latest released version of the Apache Struts. This is necessary to prevent your publicly accessible web site, which is using the Struts REST plugin and performing XML serialisation, from being exposed to possible DoS attack.

You can find more details in a Security Bulletin S2-056

All developers are strongly advised to perform this action.

23 March 2018 - Immediately upgrade commons-fileupload to version 1.3.3

The Apache Struts Team recommends to immediately upgrade your Struts 2 based projects to use the latest released version of Commons FileUpload library, which is currently 1.3.3. This is necessary to prevent your publicly accessible web site from being exposed to possible Remote Code Execution attacks (see [1] [2]).

This affects any Struts version prior to 2.5.12 [3].

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>1.3.3</version>
</dependency>

More details can be found here:

  2. https://nvd.nist.gov/vuln/detail/CVE-2016-1000031
  3. https://issues.apache.org/jira/browse/WW-4812

All developers are strongly advised to perform this action.
