Title
Fireware OS NULL Pointer Dereference in Management Interface Allows Unauthenticated Denial of Service
Summary
A NULL pointer dereference vulnerability in WatchGuard Fireware OS’s management interface allows a remote, unauthenticated attacker with network access to the management interface to crash the management service by sending a specially crafted login request. Repeated exploitation terminates all active administrator sessions and in-progress management operations and can prevent management of the device. Traffic processing is not affected.
