Apache Struts 2 'method:' Prefix Arbitrary Remote Command Execution

high Nessus Plugin ID 119728

Language:

Synopsis

The remote web server contains a web application that uses a Java framework, which 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. When Dynamic Method Invocation is enabled, it is possible to pass a malicious expression to the 'method:' prefix. A remote, unauthenticated attacker can exploit this issue to execute arbitrary commands on the remote web server.

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

Solution

Upgrade to version 2.3.28.1 or later.
