Bastille Threat Research Team Tracking Number 3
Document version: 1.1
Cert VU#981271
A vulnerability has been discovered that allows a device to be paired with
a Dell KM714 dongle that presents itself as a mouse, but is actually a keyboard.
This permits keystroke injection without a keyboard being visible to the host
operating system.
This vulnerability allows an attacker to pair a fake mouse with a target
Dell KM714 dongle, and use the fake mouse to inject keystrokes into the target
computer. The Logitech Unifying dongle presents the new device as a mouse, so
the user would be unaware that a "keyboard" was paired with their dongle.
Affected Platforms
The following products have been tested and shown to be affected:
- Dell KM714 Wireless Keyboard and Mouse Combo
- Dell KM714 USB dongle (USB ID 046d:c52b)
Exploiting this vulnerability involves transmitting RF packets to a Dell KM714
dongle, which requires physical proximity to the target computer.
