Apache Struts 2 before 2.3.14.3 allows remote attackers to execute arbitrary OGNL code via a request with a crafted value that contains both "${}" and "%{}" sequences, which causes the OGNL code to be evaluated twice.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - Apache Struts 2 before 2.3.14.3 allows remote attackers to execute arbitrary OGNL code via a request with
    a crafted value that contains both "${}" and "%{}" sequences, which causes the OGNL code to be evaluated
    twice. (CVE-2013-2135)

The version of Apache Struts running on the remote host is 2.x prior to 2.3.14.3. It, therefore, is affected by a remote command execution vulnerability.

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

The remote web application appears to use Struts 2, a web framework that utilizes OGNL (Object-Graph Navigation Language) as an expression language. Due to a flaw in the evaluation of an OGNL expression, a remote, unauthenticated attacker can exploit this issue to execute arbitrary commands on the remote web server by sending a specially crafted HTTP request.

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