The Microsoft Office product installed on the remote host is missing security updates. It is, therefore, affected by multiple vulnerabilities:
Microsoft Excel Remote Code Execution Vulnerability (CVE-2020-17123, CVE-2020-17128)
Microsoft Excel Information Disclosure Vulnerability (CVE-2020-17126)
Microsoft Outlook Information Disclosure Vulnerability (CVE-2020-17119)
Microsoft PowerPoint Remote Code Execution Vulnerability (CVE-2020-17124)
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
