Critical Azure Cosmos DB Bug Allows Full Cloud Account Takeover

A critical security vulnerability in Microsoft’s Azure cloud database platform has come to light. The flaw, which lies in Cosmos DB, could have allowed for a full remote takeover of accounts before it was patched. It is unclear whether Microsoft customers were breached during the several months in which the flaw remained exploitable. Attackers could have leveraged the bug to achieve admin rights to read, delete, or write information to a database instance.
