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 Excel software when the software fails to properly handle objects in memory.

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

 - An information disclosure vulnerability exists when Microsoft SharePoint Server fails to properly handle objects in memory.

 - An information disclosure vulnerability exists when Microsoft SharePoint Server improperly discloses its folder structure when rendering specific web pages.

 - 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.

 - This vulnerability is caused when SharePoint Server does not properly sanitize a specially crafted 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 2019 installation on the remote host is missing security updates. It is, therefore, affected by multiple vulnerabilities :

  - An information disclosure vulnerability exists when     Microsoft SharePoint Server fails to properly handle     objects in memory. An attacker who successfully     exploited this vulnerability could obtain information to     further compromise the users system.  (CVE-2020-16948,     CVE-2020-16950, CVE-2020-16953)

  - An information disclosure vulnerability exists when     Microsoft SharePoint Server improperly discloses its     folder structure when rendering specific web pages. An     attacker who took advantage of this information     disclosure could view the folder path of scripts loaded     on the page. To take advantage of the vulnerability, an     attacker would require access to the specific SharePoint     page affected by this vulnerability. The security update     addresses the vulnerability by correcting how scripts     are referenced on some SharePoint pages.
    (CVE-2020-16941, CVE-2020-16942)

  - 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-2020-16951, CVE-2020-16952)

  - This vulnerability is caused when SharePoint Server does     not properly sanitize a specially crafted request to an     affected SharePoint server. An authenticated attacker     could exploit this vulnerability by sending a specially     crafted request to an affected SharePoint server. The     attacker who successfully exploited this 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 victim,     such as change permissions, delete content, steal     sensitive information (such as browser cookies) and     inject malicious content in the browser of the victim.
    For this vulnerability to be exploited, a user must     click a specially crafted URL that takes the user to a     targeted SharePoint Web App site. In an email attack     scenario, an attacker could exploit the vulnerability by     sending an email message containing the specially     crafted URL to the user of the targeted SharePoint Web     App site and convincing the user to click the specially     crafted URL.  (CVE-2020-16944)

  - 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-2020-16945,     CVE-2020-16946)
