Year: 2021

Microsoft recently mitigated a vulnerability reported by a security researcher in the Azure Container Instances (ACI) that could potentially allow a user to access other customers’ information in the ACI service. Our investigation surfaced no unauthorized access to customer data. Out of an abundance of caution we notified customers with containers running on the same clusters as the researchers via Service Health Notifications in the Azure Portal.

On August 12, 2021, a security researcher reported a vulnerability in the Azure Cosmos DB Jupyter Notebook feature that could potentially allow a user to gain access to another customer’s resources by using the account’s primary read-write key. We mitigated the vulnerability immediately.
Our investigation indicates that no customer data was accessed because of this vulnerability by third parties or security researchers.

Microsoft is excited to announce the launch of a new, three-month security research challenge under the Azure Security Lab initiative. The Azure Server-Side Request Forgery (SSRF) Research Challenge invites security researchers to discover and share high impact SSRF vulnerabilities in Microsoft Azure. Qualified submissions are eligible for bounty rewards up to $60,000 USD, with additional awards for identifying innovative or novel attack patterns.
