At the Microsoft Security Response Center, we are committed to continuously improving the security and performance of our services to meet the evolving needs of our customers. We are excited to announce the rollout of the latest version of our Common Vulnerability Reporting (CVRF) API. This update brings improvements in both security and performance, without requiring any changes to your existing invocation methods.

The Microsoft Security Response Center (MSRC) has always been at the forefront of addressing cyber threats, privacy issues, and abuse arising from Microsoft Online Services. Building on our commitment, we have introduced several key updates to the Report Abuse Portal and API, which will significantly improve the way we handle and respond to abuse reports.

Welcome to the second installment in our series on transparency at the Microsoft Security Response Center (MSRC). In this ongoing discussion, we discuss our commitment to provide comprehensive vulnerability information to our customers. At MSRC, our mission is to protect our customers, communities, and Microsoft, from current and emerging threats to security and privacy.

Summary On May 9, 2024, Microsoft successfully addressed multiple vulnerabilities within the Azure Machine Learning (AML) service, which were initially discovered by security research firms Wiz and Tenable. These vulnerabilities, which included Server-Side Request Forgeries (SSRF) and a path traversal vulnerability, posed potential risks for information exposure and service disruption via Denial-of-Service (DOS).

Summary Microsoft Security Response Center (MSRC) was notified in January 2024 by our industry partner, Tenable Inc., about the potential for cross-tenant access to web resources using the service tags feature. Microsoft acknowledged that Tenable provided a valuable contribution to the Azure community by highlighting that it can be easily misunderstood how to use service tags and their intended purpose.

At the Microsoft Security Response Center (MSRC), our mission is to protect our customers, communities, and Microsoft from current and emerging threats to security and privacy. One way we achieve this is by determining the root cause of security vulnerabilities in Microsoft products and services. We use this information to identify vulnerability trends and provide this data to our Product Engineering teams to enable them to systematically understand and eradicate security risks.
