Technical details
This vulnerability is an authentication bypass in Microsoft Entra ID that exploits an alternate path or channel in the authentication mechanism, allowing an unauthenticated remote attacker to elevate privileges over the network. The vulnerability does not require user interaction or pre-existing privileges. An attacker can bypass the primary authentication controls by leveraging an unprotected secondary channel, leading to complete compromise of affected identities and potential lateral movement throughout the cloud infrastructure. Microsoft has released patches through their Security Update Guide.
