services / Azure / Cosmos DB database account

An Azure Cosmos DB (DocumentDB) database account, the top-level control-plane resource that hosts databases and containers and governs endpoints, regions, consistency, networking, identity, and backup configuration. It is a primary production data store.

Account master keys are root-equivalent data-plane credentials granting full read/write access to all data in the account, which makes this resource type security-sensitive.

Microsoft.​DocumentDB/​databaseAccounts/​regenerateKey/​action

Regenerates one of the account's master keys, invalidating the copy held by legitimate applications and administrators and cutting off their access (denial of service). Note that regeneration invalidates the rotated key rather than granting the attacker any durable new credential.

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.
