"The version of Apache Struts running on the remote host is 2.x prior to to 2.3.20. It, therefore, is affected by
multiple class loader vulnerabilities:

  - A class loader vulnerability exists in ParametersInterceptor due to improper access restriction to the getClass
    method. A remote, unauthenticated attacker can exploit this to manipulate the ClassLoader and execute arbitrary
    code. (CVE-2014-0112)

  - A class loader vulnerability exists in CookieInterceptor due to improper access restriction to the getClass. A
    remote, unauthenticated attacker can exploit this, via a specially crafted request which uses a wildcard cookiesName
    value to manipulate the ClassLoader and execute arbitrary code. (CVE-2014-0113)

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