Apache Struts CVE-2018-11776 Results With No Namespace Possible Remote Code Execution (S2-057)

Critical Nessus Plugin ID 112036

Synopsis

A web application running on the remote host uses a Java framework that is affected by a possible remote code execution.

Description

The version of Apache Struts running on the remote host is 2.3.x prior to 2.3.35, or 2.5.x prior to 2.5.17. It, therefore, contains a possible remote code execution vulnerability when results are used without setting a namespace along with an upper action that does not have a namespace set or has a wildcard namespace set.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Apache Struts version 2.3.35 or 2.5.17 or later
