Microsoft Entra (AzureAD) - Entra Group Takeover
Category | SECURITY_MISCONFIGURATION |
Base Score | 5.9 |
Description
Microsoft Entra uses Role-Based Access Controls (RBACs) to manage permissions within a tenant account. Some Directory Roles, such as the Hybrid Identity Administrator, can allow a user to assign themselves as the owner of a Group. Once the owner of a Group, a user can modify group RBACs and group membership.
Impact
If an attacker is able to manipulate an Entra Group that has assigned high-value administrator roles, an attacker could escalate an unprivileged user by adding them to the group once they become owner.
