## Technical details

An authorization bypass in Windows DHCP filter-list handling in DDI Central 6.3.0 build 6300 fails to verify cluster membership before allowing configuration changes. An authenticated non-administrator operator with access to one cluster can modify allow/deny filter lists on DHCP servers in other clusters they are not authorized to access. The vulnerability is fixed in build 6301 by adding cluster permission checks.
