According to its self-reported version number, the Microsoft SharePoint application running on the remote host is affected by multiple vulnerabilities :

 - A remote code execution vulnerability exists in Microsoft SharePoint when the software fails to check the source markup of an application package.

 - 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 information disclosure vulnerability exists in SharePoint Server.

 - A spoofing vulnerability exists when Microsoft SharePoint Server does not properly sanitize a specially crafted web request to an affected SharePoint server.

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

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 it fails to properly handle     objects in memory. An attacker who successfully     exploited the vulnerability could use a specially     crafted file to perform actions in the security context     of the current user. For example, the file could then     take actions on behalf of the logged-on user with the     same permissions as the current user.  (CVE-2020-0980)

  - A remote code execution vulnerability exists in     Microsoft SharePoint when the software fails to check     the source markup of an application package. An attacker     who successfully exploited the vulnerability could run     arbitrary code in the context of the SharePoint     application pool and the SharePoint server farm account.
    Exploitation of this vulnerability requires that a user     uploads a specially crafted SharePoint application     package to an affected version of SharePoint. The     security update addresses the vulnerability by     correcting how SharePoint checks the source markup of     application packages. (CVE-2020-0920, CVE-2020-0929,     CVE-2020-0931, CVE-2020-0932, CVE-2020-0971,     CVE-2020-0974)

  - 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-2020-0923,     CVE-2020-0924, CVE-2020-0925, CVE-2020-0926,     CVE-2020-0927, CVE-2020-0930, CVE-2020-0933,     CVE-2020-0954, CVE-2020-0973, CVE-2020-0978)

  - A spoofing 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-2020-0972,     CVE-2020-0975, CVE-2020-0976, CVE-2020-0977)

The Microsoft Business Productivity Server installation on the remote host is missing a security update. It is, therefore, affected by the following vulnerability :
