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

  - An elevation of privilege 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. These 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-2018-8149,     CVE-2018-8155, CVE-2018-8156, CVE-2018-8168)

  - 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-2018-8161)

  - An information disclosure vulnerability exists in     Outlook when a message is opened. This vulnerability     could potentially result in the disclosure of sensitive     information to a malicious site.  (CVE-2018-8160)

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

  - 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-2018-8161)

  - An information disclosure vulnerability exists in     Outlook when a message is opened. This vulnerability     could potentially result in the disclosure of sensitive     information to a malicious site.  (CVE-2018-8160)

The Microsoft Office Products are missing security updates.
It is, therefore, affected by multiple vulnerabilities :

  - A remote code execution vulnerability exists in     Microsoft Excel 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-2018-8147, CVE-2018-8148)

  - An information disclosure vulnerability exists in     Outlook when a message is opened. This vulnerability     could potentially result in the disclosure of sensitive     information to a malicious site.  (CVE-2018-8160)

  - 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-2018-8157, CVE-2018-8158,     CVE-2018-8161)

  - A remote code execution vulnerability exists in     Microsoft InfoPath 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-2018-8173)

  - A security feature bypass vulnerability exists when the     Microsoft Outlook attachment block filter does not     properly handle attachments. An attacker who successfully     exploited the vulnerability could execute arbitrary     commands. The security feature bypass by itself does not     allow arbitrary code execution. (CVE-2018-8150)

The Microsoft Word Products are missing a security update.
It is, therefore, affected by the following vulnerability :

  - 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-2018-8161)
