Compatible with Windows XP/7/8/8.1/10, Mac OS, Linux, Android and etc. " Due to unencrypted and unauthenticated data communication, the wireless presenter Inateck WP2002 is prone to keystroke injection attacks. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Vulnerability Details: SySS GmbH found out that the wireless presenter Inateck WP2002 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 an Inateck WP2002 wireless presenter. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Proof of Concept (PoC): SySS GmbH could successfully perform keystroke injection attacks against the wireless presenter Inateck WP2002 using the open-source software tool Universal Radio Hacker [2] in combination with the software-defined radio HackRF One [3]. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Solution: SySS GmbH is not aware of a solution for this reported security vulnerability. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Disclosure Timeline: 2019-03-22: Vulnerability reported to manufacturer 2019-06-04: Public release of security advisory ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ References: [1] Product website for Inateck WP2002 https://www.inateck.com/de/kabellos-praesentationsgeraet-laiserpointer-presenter-fernbedienung-powerpoint-keynote-usb-adapter-plug-and-play-schwarz-wp2002.html [2] Universal Radio Hacker (URH) https://github.com/jopohl/urh [3] HackRF One by Great Scott Gadgets https://greatscottgadgets.com/hackrf/ [4] SySS Security Advisory SYSS-2019-008 https://www.syss.de/fileadmin/dokumente/Publikationen/Advisories/SYSS-2019-008.txt [5] SySS Responsible Disclosure Policy https://www.syss.de/en/responsible-disclosure-policy/ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Credits: This security vulnerability was found by Matthias Deeg of SySS GmbH.
