The Microsoft SharePoint installation on the remote host is 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-2020-1495)

  - 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-2020-1499,     CVE-2020-1500, CVE-2020-1501)


  - 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-2020-1505)

  - An information disclosure vulnerability exists when     Microsoft Word improperly discloses the contents of its     memory. An attacker who exploited the vulnerability     could use the information to compromise the users     computer or data.  (CVE-2020-1503,     CVE-2020-1583)

  - 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-2020-1573,     CVE-2020-1580)
