  - 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 2010 installation on the remote host is missing security updates. It is, therefore, affected by multiple vulnerabilities:

  - An unspecified tampering vulnerability. (CVE-2021-1718)
