FastTrack Admin By Request 6.1.0.0 supports group policies that are supposed to allow only a select range of users to elevate to Administrator privilege at will. When a user requests elevation using the AdminByRequest.exe interface, the interface communicates with the underlying service (Audckq32.exe) using a .NET named pipe. If the underlying service responds that a user is permitted access to the elevation feature, the client then reinitiates communication with the underlying service and requests elevation. This elevation request has no local checks in the service, and depends on client-side validation in the AdminByRequest.exe interface, i.e., it is a vulnerable exposed functionality in the service. By communicating directly with the underlying service, any user can request elevation and obtain Administrator privilege regardless of group policies or permissions.

FastTrack Admin By Request 6.1.0.0 supports group policies that are supposed to allow only a select range of users to elevate to Administrator privilege at will. If a user does not have direct access to the elevation feature through group policies, they are prompted to enter a PIN code in a challenge-response manner upon attempting to elevate privileges. The challenge's response uses a simple algorithm that can be easily emulated via data (customer ID and device name) available to all users, and thus any user can elevate to Administrator privilege.

The HTTP client and server in giFT-FastTrack 0.8.6 and earlier allows remote attackers to cause a denial of service (crash), possibly via an empty search query, which triggers a NULL dereference.

fasttrack p2p, as used in (1) KaZaA, (2) grokster, and (3) morpheus allows remote attackers to spoof other users by modifying the username and network information in the message header.

fasttrack p2p, as used in (1) KaZaA before 1.5, (2) grokster, and (3) morpheus allows remote attackers to cause a denial of service (memory exhaustion) via a series of client-to-client messages, which pops up new windows per message.
