Earlier this week, a ‘severe’ vulnerability was discovered in Apache Struts, an open source framework for developing applications in Java. The vulnerability, CVE-2017-9805, affects all versions of Struts since 2008 and all applications using the framework’s REST plugin are vulnerable. Trend Micro has released DVToolkit CSW file CVE-2017-9805.csw for the Apache Struts 2 Vulnerability to customers using TippingPoint solutions. The CSW file includes the following filters:

Filter C000001: HTTP: Apache Struts 2 XStreamHandler Command Injection Vulnerability

This filter detects an attempt to exploit a command injection vulnerability in Apache Struts 2. The specific flaw exists due to a failure to properly validate requests sent to the REST plugin with the XStream handler. An attacker can leverage this vulnerability to execute code under the context of the application. Note: This filter will be obsoleted by MainlineDV filter 29580.

Filter C000002: HTTP: Apache Struts 2 XStreamHandler Suspicious XML Command Usage

This filter detects usage of suspicious XML objects. Apache Struts 2 is known to be vulnerable to command injection flaws when the REST plugin is used with the XStream handler. While not inherently malicious the serialized data can be used for command injection. Note: This filter will be obsoleted by MainlineDV filter 29572.
