Synopsis

Microsoft SharePoint Server 2019 build < 16.0.10345.12101 Multiple Vulnerabilities

Description

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 when Microsoft SharePoint Server does not properly sanitize a specially crafted web request to an affected SharePoint server.

- A spoofing 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 Server when it fails to properly identify and filter unsafe ASP.

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

- 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.

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

Solution
