Guest User Chaos: Microsoft’s Entra Feature Sparks Azure Security Concerns
Guest users in Microsoft Entra can create subscriptions in Azure tenants without admin permissions, gaining “Owner” rights. While intended for complex setups, this feature can be exploited, leading to unexpected control over resources. Enabling subscription policies and auditing guest accounts can help avoid turning your cloud into a hacker’s playground.
Hot Take:
Who would have thought that Microsoft’s Entra identity platform would come with a built-in magic trick for guest users? They can poof themselves into subscription Owners without needing admin privileges! It’s like handing them the keys to your digital kingdom and saying, “Try not to burn it down!”
Key Points:
- Guest users in Microsoft Azure can create and transfer subscriptions without admin privileges.
- This feature is by design and not a bug, according to Microsoft.
- Guest users with specific billing roles can gain “Owner” rights over new subscriptions.
- Once an Owner, guests can exploit advanced capabilities within the host tenant.
- Microsoft provides controls to limit this, but they are not enabled by default.
