An elevation of privilege vulnerability exists in Microsoft SharePoint, aka 'Microsoft SharePoint Elevation of Privilege Vulnerability'.

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

 - An elevation of privilege vulnerability exists in Microsoft SharePoint.

 - A spoofing vulnerability exists in Microsoft SharePoint when it improperly handles requests to authorize applications, resulting in cross-site request forgery (CSRF).

 - 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.

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

 - A remote code execution vulnerability exists in Microsoft SharePoint where APIs aren't properly protected from unsafe data input.

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 :

  - 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-2019-1260)

  - 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-2019-1262)

  - A remote code execution vulnerability exists in     Microsoft SharePoint where APIs aren't properly     protected from unsafe data input. 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     access a susceptible API on an affected version of     SharePoint with specially-formatted input. The security     update addresses the vulnerability by correcting how     SharePoint handles deserialization of untrusted data.
    (CVE-2019-1295, CVE-2019-1296)

  - 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-2019-1257)

  - A spoofing vulnerability exists in Microsoft SharePoint     when it improperly handles requests to authorize     applications, resulting in cross-site request forgery     (CSRF).  (CVE-2019-1259, CVE-2019-1261)
