Apache Struts 2 2.3.20 through 2.3.28.1 mishandles token validation, which allows remote attackers to conduct cross-site request forgery (CSRF) attacks via unspecified vectors.

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

  - Apache Struts 2 2.3.20 through 2.3.28.1 mishandles token validation, which allows remote attackers to
    conduct cross-site request forgery (CSRF) attacks via unspecified vectors. (CVE-2016-4430)

The version of Apache Struts running on the remote Windows host is 2.x prior to 2.3.29. It is, therefore, affected by the following vulnerabilities :

  - A remote code execution vulnerability exists due to     erroneously performing double OGNL evaluation of     attribute values assigned to certain tags. An     unauthenticated, remote attacker can exploit this, via a     specially crafted request, to execute arbitrary code.
    (CVE-2016-0785)

  - A cross-site request forgery (XSRF) vulnerability exists     due to improper validation of session tokens. An     unauthenticated, remote attacker can exploit this, via a     malicious OGNL expression, to bypass token validation     and perform an XSRF attack. (CVE-2016-4430)

  - Multiple input validation issues exists that allow     internal security mechanisms to be bypassed, allowing     the manipulation of a return string which can be used to     redirect users to a malicious website. This affects both     the default action method the 'getter' action method.
    (CVE-2016-4431, CVE-2016-4433)

  - An unspecified flaw exists that is triggered during the     cleanup of action names. An unauthenticated, remote     attacker can exploit this, via a specially crafted     payload, to perform unspecified actions. (CVE-2016-4436)

  - A remote code execution vulnerability exists in the REST     plugin due to improper handling of OGNL expressions. An     unauthenticated, remote attacker can exploit this, via     a specially crafted OGNL expression, to execute     arbitrary code. (CVE-2016-4438)

  - A remote code execution vulnerability exists in user tag     attributes due to improper handling of OGNL expressions.     An unauthenticated, remote attacker can exploit this,     via a specially crafted double OGNL evaluation, to     execute arbitrary code. (CVE-2016-4461)

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