How to fix or mitigate CVE-2020-37020?

Within 24 hours: Inventory all SonarQube 8.3.1 instances and assess which systems have untrusted local users or service accounts with file system access. Within 7 days: Implement network segmentation to restrict local access to SonarQube servers and apply OS-level access controls to the SonarQube installation directory. Within 30 days: Plan and execute an upgrade to SonarQube 8.4 or later, or migrate to a patched version; if upgrade is not immediately feasible, implement service hardening by running SonarQube under a least-privilege local service account and apply file system permissions to prevent unauthorized modification of the service executable path.
