-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Advisory ID: SYSS-2016-074 Product: Wireless Presenter R400 Manufacturer: Logitech Affected Version(s): Model R-R0008 Tested Version(s): Model R-R0008 Vulnerability Type: Insufficient Verification of Data Authenticity (CWE-345) Keystroke Injection Vulnerability Risk Level: High Solution Status: Open Manufacturer Notification: 2016-08-12 Solution Date: - Public Disclosure: 2016-10-12 CVE Reference: Not yet assigned Authors of Advisory: Matthias Deeg (SySS GmbH) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Overview: Logitech R400 is a wireless presenter using 2.4 GHz radio communication. The manufacturer describes the product as follows (see [1]): "Intuitive controls and red laser pointer make presentations a snap, even in the darkest auditoriums." Due to unencrypted and unauthenticated data communication, the wireless presenter Logitech R400 is prone to keystroke injection attacks. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Vulnerability Details: The SySS GmbH found out that the wireless presenter Logitech R400 is vulnerable to keystroke injection attacks. An attacker can analyze the unencrypted and unauthenticated data packets of the 2.4 GHz radio communication sent by the wireless presenter to the receiver (USB dongle) in order to learn the used protocol. By knowing the used data protocol, it is possible to inject packets in the data communication that are actually interpreted as keystrokes by the receiver on the target system. Thus, an attacker is able to send arbitrary keystrokes to a victim's computer system, for example in order to install malware when the target system is unattended. In this way, an attacker can remotely take control over the victim's computer that is operated with an affected receiver of a Logitech R400 wireless presenter. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Proof of Concept (PoC): The SySS GmbH could successfully perform keystroke injection attacks against the wireless presenter Logitech R400 using an in-house developed software tool in combination with the USB radio dongle Crazyradio PA and the nrf-research-firmware by Bastille Networks Internet Security (see [2] and [3]). The following output of the developed proof-of-concept software tool illustrates a successful attack: # python logitech_presenter.py -a 77:E3:96:AC:07 _____ ______ ___ _ _ _____ _ _ | __ \| ____|__ \| || | | __ \| | | | _ __ | |__) | |__ ) | || |_ | |__) | | __ _ _ _ ___ ___| |_ | '_ \| _ /| __| / /|__ _| | ___/| |/ _` | | | / __|/ _ \ __| | | | | | \ \| | / /_ | | | | | | (_| | |_| \__ \ __/ |_ |_| |_|_| \_\_| |____| |_| |_| |_|\__,_|\__, |___/\___|\__| __/ | |___/ Logitech Wireless Presenter Attack Tool v1.0 by Matthias Deeg - SySS GmbH (c) 2016 [*] Configure nRF24 radio [*] Scanning for Logitech wireless presenter ...
