-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Advisory ID: SYSS-2016-046 Product: PERIDUO-710W Manufacturer: Perixx Computer GmbH Affected Version(s): Part No. KG-1027 Tested Version(s): Part No. KG-1027 Vulnerability Type: Cryptographic Issues (CWE-310) Missing Protection against Replay Attacks Risk Level: Medium Solution Status: Open Manufacturer Notification: 2016-05-27 Solution Date: - Public Disclosure: 2016-07-29 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 an insecure implementation of the encrypted data communication, the wireless keyboard PERIDUO-710W is prone to replay attacks. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Vulnerability Details: The SySS GmbH found out that the wireless keyboard PERIDUO-710W is prone to replay attacks. An attacker can sniff the AES-encrypted data packets of the 2.4 GHz radio communication sent by the keyboard to the transceiver (USB dongle) and replay the recorded communication data at will causing the same effect as the original data communication. A replay attack against the keyboard can, for example, be used to gain unauthorized access to a computer system that is operated with a vulnerable PERIDUO-710W keyboard. In this attack scenario, an attacker records the radio communication during a password-based user authentication of his or her victim, for instance during a login to the operating system or during unlocking a screen lock. At an opportune moment when the victim's computer system is unattended, the attacker approaches the victim's computer and replays the previously recorded AES-encrypted data communication for the password-based user authentication and thereby gets unauthorized access to the victim's system. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Proof of Concept (PoC): The SySS GmbH could successfully perform a replay attack as described in the previous section using the USB radio dongle Crazyradio PA (see [3]) and an in-house developed proof-of-concept software tool. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Solution: The SySS GmbH is not aware of a solution for this reported security vulnerability. For further information please contact the manufacturer. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Disclosure Timeline: 2016-05-27: Vulnerability reported to manufacturer 2016-06-06: Vulnerability reported to manufacturer again 2016-07-29: 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 Security Advisory SYSS-2016-046 https://www.syss.de/fileadmin/dokumente/Publikationen/Advisories/SYSS-2016-046.txt [5] 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.
