services / Google Cloud / Google Cloud SQL

A Cloud SQL instance is a VM managed by Google that runs the SQL database instance (as well as any accompanying containers)

Cloud SQL is used to store and serve sensitive and application-critical data. Breach of a cloud SQL database can lead to exfiltration of highly sensitive data, or interruption of mission-critical applications.

cloudsql.​instances.​failover

This causes Cloud SQL to switch to serving data from a secondary instance instead of the primary. Google expects the failover operation to render the instance inaccessible for about 60 seconds, so this could produce a DOS if executed repeatedly.

Risks

1. Denial-of-service (HIGH)

Scope: CRITICAL

This privilege may grant access to sensitive data from a significant fraction of organizational functions, allow interruption of critical organizational services, or its exploit could lead to significant privilege escalation.
