Microsoft SharePoint Server Spoofing Vulnerability

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

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 2013 installation on the remote host is missing security updates. It is, therefore, affected by multiple vulnerabilities:

  - A session spoofing vulnerability exists. An attacker can exploit this to perform actions with the     privileges of another user. (CVE-2021-1641, CVE-2021-1717)

  - A remote code execution vulnerability. An attacker can exploit this to bypass authentication and execute     unauthorized arbitrary commands. (CVE-2021-1707, CVE-2021-1714, CVE-2021-1715, CVE-2021-1716)

  - An elevation of privilege vulnerability. An attacker can exploit this to gain elevated privileges.
    (CVE-2021-1712)     Note that Nessus has not tested for this issue 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:

  - A session spoofing vulnerability exists. An attacker can exploit this to perform actions with the     privileges of another user. (CVE-2021-1641, CVE-2021-1717)

  - An elevation of privilege vulnerability. An attacker can exploit this to gain elevated privileges.
    (CVE-2021-1712, CVE-2021-1719)

  - A remote code execution vulnerability. An attacker can exploit this to bypass authentication and execute     unauthorized arbitrary commands. (CVE-2021-1707, CVE-2021-1715, CVE-2021-1716)     Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version   number.

The Microsoft SharePoint Server 2016 installation on the remote host is missing security updates. It is, therefore, affected by multiple vulnerabilities:

  - A session spoofing vulnerability exists. An attacker can exploit this to perform actions with the     privileges of another user. (CVE-2021-1641, CVE-2021-1717)

  - An elevation of privilege vulnerability. An attacker can exploit this to gain elevated privileges.
    (CVE-2021-1712, CVE-2021-1719)
