The NetworkInterface::getHost function in NetworkInterface.cpp in ntopng before 3.0 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via an empty field that should have contained a hostname or IP address.
A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
