Original description The description as published by the source.
A flaw was found in dnsmasq. When DHCP leasequery is enabled without listing allowed source addresses, the server does not check who sent the query. A host on the local network can request DHCP lease records and learn assigned addresses, MAC addresses, hostnames, and related lease metadata. The feature is off unless an administrator turns it on.
