CWE-311: Missing Encryption of Sensitive Data

Multiple wireless input devices (keyboard and mouse) use a proprietary wireless protocol on the 2.4 GHz ISM band that lacks proper encryption. An attacker within wireless transmission range can inject keystrokes or read keystroke data, or cause the victim's device to pair with a new input device. Wireless range on these models varies but is typically a few meters within a home.

The researchers have released a website as well as advisories with more details.

This vulnerability does not impact Bluetooth devices.

An attacker within wireless transmission range can inject keystrokes on the victim's device, or cause the victim's device to pair with a new input device.

Update device firmware

According to the researcher, Logitech has released an updated firmware for their devices to address this issue. Please contact Logitech customer support for more information.

Users of other models should consider individual use cases and threat models when using the devices until an update is available.
