Security Updates for Microsoft Dynamics 365 (on-premises) (Oct 2021)

medium Nessus Plugin ID 154172
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The Microsoft Dynamics 365 (on-premises) is affected by multiple vulnerabilities.


The Microsoft Dynamics 365 (on-premises) installation on the remote host is missing security updates. It is, therefore, affected by multiple vulnerabilities:

- A spoofing vulnerability (CVE-2021-41353)

- A cross-site scripting vulnerability (CVE-2021-41354)

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


Microsoft has released the following security updates to address this issue:
