"The version of Apache Struts installed on the remote host is prior to 2.3.18. It is, therefore, affected by a
vulnerability as referenced in the S2-008 advisory.

  - The DebuggingInterceptor component in Apache Struts before 2.3.1.1, when developer mode is used, allows 
    remote attackers to execute arbitrary commands via unspecified vectors. NOTE: the vendor characterizes 
    this behavior as not a security vulnerability itself. (CVE-2012-0394)

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