Apache Struts XStream Handler REST Plugin XML Request Handling Remote DoS (S2-056)

high Nessus Plugin ID 108760

Language:

Synopsis

A web application running on the remote host uses a Java framework that is affected by remote denial of service attack.

Description

The version of Apache Struts running on the remote host is prior to 2.5.16. It, therefore, contains a flaw in the REST plugin when using the XStream handler that is triggered during the handling of a specially crafted request with an XML payload. This may allow a remote attacker to cause a denial of service.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Apache Struts version 2.5.16 or later or apply the workaround as referenced in the vendor's security bulletin.
