CVSS vector description

Metric	Value	Metric Description	Value Description
Attack vector	Network	AV	The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, up to and including the entire Internet. Such a vulnerability is often termed “remotely exploitable” and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers). An example of a network attack is an attacker causing a denial of service by sending a specially crafted TCP packet across a wide area network (e.g., CVE-2004-0230).
Attack Complexity	Low	AC	The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Privileges Required	None	PR	The attacker is unauthenticated prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
User Interaction	None	UI	The vulnerable system can be exploited without interaction from any human user, other than the attacker. Examples include: a remote attacker is able to send packets to a target system a locally authenticated attacker executes code to elevate privileges
Scope	Unchanged	S	An exploited vulnerability can only affect resources managed by the same security authority. In the case of a vulnerability in a virtualized environment, an exploited vulnerability in one guest instance would not affect neighboring guest instances.
Confidentiality	None	C	There is no impact on the confidentiality of the system; the attacker does not gain the ability to read any data.
Integrity	None	I	There is no impact on the integrity of the system; the attacker does not gain the ability to modify any files or information on the target system.
Availability	High	A	There is a total shutdown of the affected resource. The attacker can deny access to the system or data, potentially causing significant loss to the organization.

Perixx Computer PERIDUO-710W Insufficient ProtectionsAdvisory ID: SYSS-2016-045 Product: PERIDUO-710W Manufacturer: Perixx Computer GmbH Affected Version(s): Part No. KG-1027 Tested Version(s): Part No. KG-1027 Vulnerability Type: Insufficient Protection of Code (Firmware) and Data (Cryptographic Key) 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 the insufficient protection of the flash memory of the keyboard, an attacker with physical access to the wireless keyboard has read and write access to the firmware and the used cryptographic key. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Vulnerability Details: The SySS GmbH found out that the embedded flash memory of the wireless keyboard PERIDUO-710W can be read and written via the SPI interface of the used transceiver with an embedded microcontroller nRF24LE1H, as the flash memory is not protected by the offered read back protection feature (RDISMB - Read DISable Main Block). Thus, an attacker with physical access to the keyboard and transceiver can simply read and write the SPI-addressable code and data flash memory. Due to the use of nRF24 transceiver versions with one-time programmable memory, write access is limited in such a way that a set 1 bit can be changed to a 0 bit but not vice versa. The AES cryptographic key used by the PERIDUO-710W keyboard is accessible via the SPI interface. By having read and write access to the code and data flash memory, an attacker can either extract the cryptographic key, for instance to perform further attacks against the wireless communication, or modify the firmware or the cryptographic key in a restricted way due to the used one-time programmable memory. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Proof of Concept (PoC): The SySS GmbH could successfully read the contents of the code and data flash memory of the PERIDUO-710W keyboard using the hardware tool Bus Pirate [3] in combination with the software tool nrfprog [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: 2016-05-27: 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] Website of Bus Pirate hardware tool http://dangerousprototypes.com/docs/Bus_Pirate [4] nrfprog Github repository https://github.com/nekromant/nrfprog [5] SySS Security Advisory SYSS-2016-045 https://www.syss.de/fileadmin/dokumente/Publikationen/Advisories/SYSS-2016-045.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.
