## Technical details

An improper authorization vulnerability in Windows DHCP option handling (CWE-269) allows an authenticated operator without cluster permissions to modify DHCP options on subnets belonging to unauthorized clusters. The vulnerability exists in DDI Central 6.3.0 build 6300 due to missing scope-based permission checks before DHCP option modifications. An attacker can replace DHCP option 6 (DNS Servers) for an inaccessible subnet, redirecting clients to a malicious DNS resolver and affecting name resolution and traffic routing.
