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

  - Improper authentication in Microsoft Office SharePoint allows an authorized attacker to elevate privileges     over a network. (CVE-2026-62827)

  - Missing authentication for critical function in Microsoft Office SharePoint allows an authorized attacker     to elevate privileges over a network. (CVE-2026-64921)

  - Deserialization of untrusted data in Microsoft Office SharePoint allows an authorized attacker to execute     code over a network. (CVE-2026-63514)

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