Executive brief
Azure Active Directory is Microsoft's cloud-based identity and access management service used by millions of organizations to control user authentication and permissions. An authorized attacker could exploit a server-side request forgery vulnerability to make Azure AD perform unintended internal requests, potentially gaining elevated privileges and access to sensitive resources across the network.
Technical details
A server-side request forgery (SSRF) vulnerability in Azure Active Directory allows an authenticated attacker to craft malicious requests that cause the Azure AD service to issue requests to internal or restricted resources on their behalf. The vulnerability requires the attacker to already have authorized access to the system. By exploiting this flaw, an attacker can bypass network segmentation and access controls to elevate their privileges within the Azure AD environment. The attack is conducted over the network without requiring user interaction. Microsoft has released security updates to remediate this vulnerability.
