Apache Struts 2 before 2.3.14.2 allows remote attackers to execute arbitrary OGNL code via a crafted request that is not properly handled when using the includeParams attribute in the (1) URL or (2) A tag.

The version of Apache Struts running on the remote host is 2.x prior to 2.3.14.2. It, therefore, is affected by a remote code execution vulnerability in the URL and Anchor tags due to a flaw in handling the includeParams attribute. A remote, unauthenticated attacker can exploit this issue, via a specially crafted request to inject arbitrary OGNL code into the stack and execute arbitrary methods, bypassing Struts and OGNL library protections.

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

The version of Apache Struts running on the remote host is 2.x prior to 2.3.14.2. It, therefore, is affected by multiple vulnerabilities including a remote command execution vulnerability and a cross-site scripting (XSS) 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 this issue exists because of an incomplete fix for CVE-2013-1966. 

Note that this version of Struts 2 is reportedly also affected by multiple cross-site scripting (XSS) vulnerabilities as well as session access and manipulation attacks; however, Nessus has not tested for these issues. 

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