Workarounds

SolarWinds recommends customers upgrade to SolarWinds Platform version 2022.4 as soon as it becomes available. The expected RC release is at the end of October. SolarWinds also recommends customers to follow the guidance provided in the SolarWinds
Secure Configuration Guide
. Ensure only authorized users can access the SolarWinds Platform. Special attention should be given to the following points from documentation:

  • Be careful not to expose your SolarWinds Platform website on the public internet. If you must enable outbound
    internet access from SolarWinds servers, create a strict allow list and block all other traffic. See
    SolarWinds
    Platform Product Features Affected by Internet Access
  • Disable unnecessary ports, protocols, and services on your host operating system and on applications, like SQL
    Server. For more details, see the SolarWinds
    Port Requirements guide
     and Best
    practices for configuring Windows Defender Firewall
    (© 2021 Microsoft, available at
    https://docs.microsoft.com/en-us/windows/security/threat-protection/windows-firewall/best-practices-configuring,
    obtained on January 13, 2021.)
  • Apply proper segmentation controls on the network where you have deployed the SolarWinds Platform and SQL
    Server instances.
  • Configure the firewall for the main polling engine to limit and restrict all inbound and outbound access for
    port 5671. Port 5671 should only communicate to your other SolarWinds Servers (in case of High Availability,
    both Active and Standby Primary Polling Engine Servers). You can check these by querying the Orion Servers table
    in the SolarWinds Platform database. Ensure this rule is updated when the configuration of SolarWinds Platform
    changes, for example when you add new servers.
