  script_set_attribute(attribute:"description", value:
"The Microsoft Sharepoint Server installation on the remote
host is missing security updates. It is, therefore, affected
by multiple vulnerabilities :

  - A cross-site scripting (XSS) vulnerability exists when
    Microsoft SharePoint Server does not properly sanitize a
    specially crafted web request to an affected SharePoint
    server. An authenticated attacker could exploit the
    vulnerability by sending a specially crafted request to
    an affected SharePoint server. The attacker who
    successfully exploited the vulnerability could then
    perform cross-site scripting attacks on affected systems
    and run script in the security context of the current
    user. The attacks could allow the attacker to read
    content that the attacker is not authorized to read, use
    the victim's identity to take actions on the SharePoint
    site on behalf of the user, such as change permissions
    and delete content, and inject malicious content in the
    browser of the user. The security update addresses the
    vulnerability by helping to ensure that SharePoint
    Server properly sanitizes web requests. (CVE-2017-11775,
    CVE-2017-11777, CVE-2017-11820)

  - A remote code execution vulnerability exists in
    Microsoft Office 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-2017-11826)");
