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
