Technical details

A denial of service vulnerability exists in Microsoft Azure Active Directory due to an infinite loop (CWE-835) caused by a loop with an unreachable exit condition. An unauthenticated attacker can exploit this over the network by sending specially crafted requests to the service, leading to uncontrolled resource consumption (CWE-400). The vulnerability affects Azure Active Directory 2021 versions prior to 8.19.2. Successful exploitation results in a complete loss of availability for the affected service component. Microsoft has addressed this issue in version 8.19.2.
