Apache Struts 2 Crafted Parameter Arbitrary OGNL Expression Remote Command Execution

high Nessus Plugin ID 66935

Synopsis

The remote web server contains a web application that uses a Java framework that is affected by a remote command execution vulnerability.

Description

The remote web application appears to use Struts 2, a web framework that utilizes OGNL (Object-Graph Navigation Language) as an expression language. Due to a flaw in the evaluation of an OGNL expression, a remote, unauthenticated attacker can exploit this issue to execute arbitrary commands on the remote web server by sending a specially crafted HTTP request.

Note this issue exists because of an incomplete fix for CVE-2013-1966.

Note that this version of Struts 2 is reportedly also affected by multiple cross-site scripting (XSS) vulnerabilities as well as session access and manipulation attacks; however, Nessus has not tested for these issues.

Note that this plugin will only report the first vulnerable instance of a Struts 2 application.

Solution

Upgrade to version 2.3.14.2 or later.
