"The version of Apache Struts running on the remote host is 2.x prior to 2.3.16.2. It, therefore, is affected by
multiple vulnerabilities:

  - A denial of service vulnerability exists in MultipartStrea.java in Apache Commons FileUpload due to failure to 
    handle exceptional conditions. A remote, unauthenticated attacker can exploit this issue to cause the application
    to enter an infinite loop which may cause a denial of service condition. (CVE-2014-0050)

  - A class loader manipulation flaw exists in ParameterInterceptor due to improper validation of input data. An
    attacker can exploit this issue to bypass certain security restriction and manipulate the ClassLoader. 
    (CVE-2015-0094)

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