Workarounds

SolarWinds recommends customers upgrade to SolarWinds Platform version 2023.2 as soon as it becomes available. The expected release is by the end of April 2023. 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 the 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 (© 2023 Microsoft, available at https://docs.microsoft.com, obtained on March 28, 2023.)
• Apply proper segmentation controls on the network where you have deployed the SolarWinds Platform and SQL Server instances.
