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)
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.
