Security Updates for Microsoft Dynamics NAV (Apr 2020)

high Nessus Plugin ID 136474

Synopsis

The Microsoft Dynamics NAV install is missing a security update.

Description

The Microsoft Dynamics NAV install is missing a security update. It is, therefore, affected by the following vulnerabilities :

- An information disclosure vulnerability exists in Dynamics NAV due to the application not properly hiding the value of a masked field when showing the records as a chart page. An unauthenticated, remote attacker can exploit this to disclose potentially sensitive information. (CVE-2020-1018)

- A remote code execution vulnerability exists in Dynamics NAV due to an unspecified reason. An authenticated, remote attacker can exploit this by convincing a user to connect to a malicious Dynamics Business Central client to execute arbitrary commands. (CVE-2020-1022)

Note that Nessus has not attempted to exploit this issue but has instead relied only on the application's self-reported version number.

Solution

The solution varies for different versions of Microsoft Dynamics NAV :

- Dynamics NAV 2013 R2: Install the update package from KB4557699
- Dynamics NAV 2015: Install the update package from KB4557700
- Dynamics NAV 2016: Install Cumulative Update 54 or later
- Dynamics NAV 2017: Install Cumulative Update 41 or later
- Dynamics NAV 2018: Install Cumulative Update 28 or later
