services / Azure / DNS zone

An Azure public DNS zone is the authoritative DNS hosting resource for a domain or subdomain, containing the record sets that resolve names for that namespace.

Control over a DNS zone governs name resolution for the domain and thus traffic destination for every service under it.

Deleting the zone destroys all authoritative DNS for the domain (taking down every record set), causing resolution outage and freeing the namespace for dangling-domain re-registration/takeover.

Risks

1. Domain takeover (CRITICAL)
2. Denial-of-service (HIGH)
3. Network destruction (HIGH)

Scope: HIGH

This privilege may grant access to sensitive data from a single organizational function, or allow interruption of a service supporting a single organizational function.
