The Microsoft Sharepoint Server installation on the remote host is missing security updates. It is, therefore, affected by multiple vulnerabilities :

  - An information disclosure vulnerability exists when     Microsoft Excel software reads out of bound memory due     to an uninitialized variable, which could disclose the     contents of memory. An attacker who successfully     exploited the vulnerability could view out of bound     memory. Exploitation of the vulnerability requires that     a user open a specially crafted file with an affected     version of Microsoft Excel software. The security update     addresses the vulnerability by properly initializing the     affected variable. (CVE-2018-8627)

  - An elevation of privilege vulnerability exists when     Microsoft SharePoint Server does not properly sanitize a     specially crafted authentication request to an affected     SharePoint server. An attacker who successfully     exploited this vulnerability could execute malicious     code on a vulnerable server in the context of the     SharePoint application pool account.  (CVE-2018-8635)

  - An information disclosure vulnerability exists where     certain modes of the search function in Microsoft     SharePoint Server are vulnerable to cross-site search     attacks (a variant of cross-site request forgery, CSRF).
    When users are simultaneously logged in to Microsoft     SharePoint Server and visit a malicious web page, the     attacker can, through standard browser functionality,     induce the browser to invoke search queries as the     logged in user. While the attacker cant access the     search results or documents as such, the attacker can     determine whether the query did return results or not,     and thus by issuing targeted queries discover facts     about documents that are searchable for the logged-in     user. The security update addresses the vulnerability by     running the search queries in a way that doesnt expose     them to this browser vulnerability. (CVE-2018-8580)

  - A remote code execution vulnerability exists in     Microsoft PowerPoint software when the software fails to     properly handle objects in memory. An attacker who     successfully exploited the vulnerability could run     arbitrary code in the context of the current user. If     the current user is logged on with administrative user     rights, an attacker could take control of the affected     system. An attacker could then install programs; view,     change, or delete data; or create new accounts with full     user rights.  (CVE-2018-8628)
