A remote code execution vulnerability exists in Microsoft Word software when the software fails to properly handle objects in Protected View, aka "Microsoft Word Remote Code Execution Vulnerability." This affects Microsoft SharePoint Server, Office 365 ProPlus, Microsoft Office, Microsoft Word.

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

  - A remote code execution vulnerability exists in     Microsoft Word software when the software fails to     properly handle objects in Protected View. 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-2018-8504)

  - A remote code execution vulnerability exists in     Microsoft PowerPoint software when the software fails to     properly handle objects in Protected View. 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-2018-8501)

  - A remote code execution vulnerability exists in     Microsoft Excel software when the software fails to     properly handle objects in Protected View. 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-2018-8502)

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

An attacker     who successfully exploited the vulnerability could run     arbitrary code in the context of the current user.

The Microsoft Office Web Apps installation on the remote host is missing a security update. It is, therefore, affected by the following vulnerability :

  - A remote code execution vulnerability exists in     Microsoft Word software when the software fails to     properly handle objects in Protected View. 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-2018-8504)

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

  - A remote code execution vulnerability exists in     Microsoft Word software when the software fails to     properly handle objects in Protected View. 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-2018-8504)

  - 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-2018-8480,     CVE-2018-8488, CVE-2018-8498, CVE-2018-8518)
