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.
