Apache Struts 2.x < 2.3.28.1 Multiple Vulnerabilities

critical Nessus Plugin ID 90773

Language:

Synopsis

The remote host contains a web application that uses a Java framework that is affected by multiple vulnerabilities.

Description

The version of Apache Struts running on the remote host is 2.x prior to 2.3.28.1. It is, therefore, affected by the following vulnerabilities :

- An unspecified flaw exists, related to chained expressions, when Dynamic Method Invocation (DMI) is enabled. An unauthenticated, remote attacker can exploit this, via a crafted expression, to execute arbitrary code. (CVE-2016-3081)

- A flaw exists in XSLTResult due to a failure to sanitize user-supplied input to the 'location' parameter when determining the location of an uploaded stylesheet.
An unauthenticated, remote attacker can exploit this, via a request to a crafted stylesheet, to execute arbitrary code. (CVE-2016-3082)

- A flaw exists that is triggered when dynamic method invocation is enabled while using the REST plugin. A remote attacker can exploit this, via a specially crafted expression, to execute arbitrary code.
(CVE-2016-3087) 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 2.3.28.1 or later. Alternatively, apply the workarounds referenced in the vendor advisories.
