New Apache Struts Remote Code Execution Vulnerability

A new critical vulnerability was disclosed in Apache Struts 2, which could allow remote code execution on an affected server. It allows an attacker to execute code on a vulnerable system by sending a specially-crafted request with a malicious value in a vulnerable parameter to an affected system. 

The vulnerability (CVE-2017-9791) affects Struts versions 2.3.x with Struts 1 plugin and Struts 1 action.  Apache recommends resolving the vulnerability by always using resource keys, instead of passing raw messages to the ActionMessage, or to upgrade to Apache Struts 2.5.x as soon as possible.
