"The version of Apache Struts running on the remote host is 2.5.x 
prior to 2.5.12. It is, therefore, affected by multiple 
vulnerabilities :

  - A denial of service vulnerability exists when handling
    a specially crafted URL in a form field when the
    built-in URL validator is used. An unauthenticated,
    remote attacker can exploit this to cause the server
    process to overload. Note that this issue only affects
    version 2.5.x. (CVE-2017-7672)

  - A flaw exists in unspecified Spring AOP functionality
    that is used to secure Struts actions. An authenticated,
    remote attacker can exploit this to cause a denial of
    service condition. (CVE-2017-9787)

  - A deserialization vulnerability in Apache Commons 
    FileUpload which could be leveraged for remote
    code execution. (CVE-2016-1000031)

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