The Microsoft SharePoint Server 2010 installation on the remote host is missing security updates. It is, therefore, affected by multiple vulnerabilities :
An elevation of privilege vulnerability. An attacker can exploit this to gain elevated privileges.
(CVE-2020-17089)
An information disclosure vulnerability. An attacker can exploit this to disclose potentially sensitive information. (CVE-2020-17120)
A remote code execution vulnerability. An attacker can exploit this to bypass authentication and execute unauthorized arbitrary commands. (CVE-2020-17118, CVE-2020-17121, CVE-2020-17122)
A session spoofing vulnerability exists. An attacker can exploit this to perform actions with the privileges of another user. (CVE-2020-17115)
