|Who is Vulnerable?|
|Vulnerability Description||Apache Struts is a Java-based web application development framework. Unlike JSP and Servelets, Struts encourage good application design by enforcing MVC (Model-View-Controller) architecture for separation of concerns like business logic (Model) from web-page design (View) and navigational code (Controller).There exists a directory traversal vulnerability in the Apache Struts. The vulnerability is due to an input validation error in Struts that does not properly sanitize the URI for directory traversal patterns. Successful exploitation allows unauthenticated remote attackers to disclose or access arbitrary files on the vulnerable server.The target will not exhibit any unusual behaviour as a result of this attack. A successful attack will allow the attacker to gain access to restricted files. This may lead to disclosure of sensitive information.|
This protection will detect and block attempts to exploit this vulnerabilityNote that in order for this defense to protect your Apache Struts Server, you will need to configure port 8080 (which is also the HTTP proxy port) to work with the HTTP protocol. You need to do the following:1. In the Services tree, click on TCP > HTTP_and_HTTPS_proxy. The TCP Service Properties window opens.2. Click on Advanced. Select the Protocol Type: HTTP.
