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

high Nessus Plugin ID 112036
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


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


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.


Upgrade to Apache Struts version 2.3.35 or 2.5.17 or later
