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

  - An open redirect vulnerability exists in Microsoft     SharePoint that could lead to spoofing.  (CVE-2020-1323)

  - An elevation of privilege vulnerability exists in     Microsoft SharePoint. An attacker who successfully     exploited this vulnerability could attempt to     impersonate another user of the SharePoint server.
    (CVE-2020-1295)

  - A remote code execution vulnerability exists in     Microsoft SharePoint Server when it fails to properly     identify and filter unsafe ASP.Net web controls. An     authenticated attacker who successfully exploited the     vulnerability could use a specially crafted page to     perform actions in the security context of the     SharePoint application pool process.  (CVE-2020-1181)

  - 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-2020-1177,     CVE-2020-1183, CVE-2020-1297, CVE-2020-1298,     CVE-2020-1318, CVE-2020-1320)

  - An elevation of privilege vulnerability exists when     Microsoft SharePoint Server does not properly sanitize a     specially crafted authentication request to an affected     SharePoint server. An attacker who successfully     exploited this vulnerability could execute malicious     code on a vulnerable server in the context of the     SharePoint application pool account.  (CVE-2020-1178)

  - 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-2020-1148,     CVE-2020-1289)
