Apache Struts 2.x < Multiple Vulnerabilities

Critical Nessus Plugin ID 90773


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


The version of Apache Struts running on the remote host is 2.x prior to 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.


Upgrade to Apache Struts version or later. Alternatively, apply the workarounds referenced in the vendor advisories.
