-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Advisory ID: SYSS-2016-061 Product: PERIDUO-710W Manufacturer: Perixx Computer GmbH Affected Version(s): Part No. KG-1027 Tested Version(s): Part No. KG-1027 Vulnerability Type: Insufficient Verification of Data Authenticity (CWE-345) Mouse Spoofing Attack Risk Level: Medium Solution Status: Open Manufacturer Notification: 2016-06-28 Solution Date: - Public Disclosure: 2016-09-30 CVE Reference: Not yet assigned Authors of Advisory: Matthias Deeg and Gerhard Klostermeier (SySS GmbH) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Overview: PERIDUO-710W is a wireless desktop set consisting of a mouse and a keyboard. The manufacturer describes the product as follows (see [1]): "PERIDUO can create flexible, convenient and wireless working environment with its design. PERIDUO offers a reliable 2.4GHz high frequency penetration, low interference, and omni-directional signal transmissions with 10Meters meters [sic] receiving distance." Due to unencrypted and unauthenticated mouse data communication, the wireless desktop set PERIDUO-710W is prone to mouse spoofing attacks. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Vulnerability Details: The SySS GmbH found out that the mouse of the wireless desktop set PERIDUO-710W is prone to spoofing attacks, as the mouse data communication is unencrypted and unauthenticated. An attacker can analyze the unencrypted mouse data packets of the 2.4 GHz radio communication sent by the mouse to the receiver (USB dongle) in order to learn the used protocol. By knowing the used mouse data protocol, it is possible to spoof mouse actions like mouse movements or mouse clicks by sending forged data packets. Thus, an attacker is able to remotely control the mouse pointer of a target system that is operated with the wireless desktop set PERIDUO-710W. If the graphical user interface of the victim's system is unlocked, an attacker can for example send a list of mouse actions that start the virtual on-screen keyboard of the operating system and execute arbitrary commands in the context of the currently logged in user, for instance a download and execute attack vector. As the attacker may not have an unobstructed view to the target system's screen and may not know the used operating system, the screen resolution, or the current mouse settings, this kind mouse spoofing attack is based on heuristics. But concerning an unlocked and unattended system, an attacker can simply try different attack vectors for different target system configurations sequentially. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Proof of Concept (PoC): The SySS GmbH could successfully perform mouse spoofing attacks against a target system operated with the wireless desktop set PERIDUO-710W using an in-house developed software tool in combination with the USB radio dongle Crazyradio PA (see [3]). A proof-of-concept mouse spoofing attack resulting in remote code execution using the SySS software tool Radioactive Mouse is demonstrated in a video (see [4]). ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Solution: The SySS GmbH is not aware of a solution for this reported security vulnerability. For further information please contact the manufacturer. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Disclosure Timeline: 2016-06-28: Vulnerability reported to manufacturer 2016-09-30: Public release of the security advisory ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ References: [1] User manual for Perixx PERIDUO-710W http://perixx.com/en/service/Perixx_Manual/DUO/PERIDUO-710_manual.pdf [2] Product website for Perixx PERIDUO-710W http://perixx.com/en/products/perixx-pro-11.html [3] Product website for Crazyradio PA https://www.bitcraze.io/crazyradio-pa/ [4] SySS Proof-of-Concept Mouse Spoofing Attack Video https://www.youtube.com/watch?v=PkR8EODee44 [5] SySS Security Advisory SYSS-2016-061 https://www.syss.de/fileadmin/dokumente/Publikationen/Advisories/SYSS-2016-061.txt [6] SySS Responsible Disclosure Policy https://www.syss.de/en/responsible-disclosure-policy/ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Credits: This security vulnerability was found by Matthias Deeg and Gerhard Klostermeier of the SySS GmbH.
