Advisory ID: SYSS-2019-010 Product: Wireless Keyboard Set LX390 Manufacturer: Fujitsu Affected Version(s): Model No. GK381 Tested Version(s): Model No. GK381 Vulnerability Type: Missing Encryption of Sensitive Data (CWE-311) Risk Level: High Solution Status: Open (product reached end-of-life (EOL) in May 2019) Manufacturer Notification: 2019-04-01 Solution Date: - Public Disclosure: 2019-10-23 CVE Reference: CVE-2019-18201 Author of Advisory: Matthias Deeg (SySS GmbH)
Overview:
Fujitsu Wireless Keyboard Set LX390 is a wireless desktop set consisting
of a mouse and a keyboard.
The manufacturer describes the product as follows (see [1, 2]):
"The Wireless Keyboard Set LX390 is an excellent desktop solution for
users with ambition. This durable keyboard set is equipped with secure
2.4 GHz technology and plug and play technology. The elegant mouse works
on most surfaces due to its precise 1000 dpi sensor.
However, the payload and checksum of data packets are transmitted in an
encoded way using so-called data whitening or data scrambling of the
used 2.4 GHz radio transceiver. Thus, without knowing this data
whitening mechanism and its configuration, an attacker cannot actually
gain access to the cleartext payload contents of transmitted radio
packets during a sniffing attack.
By analyzing the Fujitsu LX390 keyboard and its radio communication,
SySS was able to identify the used communication protocol, the data
whitening mechanism, and how to find the correct data whitening
configuration by sniffing the radio communication of a specific
keyboard.
With this knowledge, an attacker can remotely analyze and decode sent
keyboard events of a Fujitsu LX390 keyboard as cleartext, for instance
keystrokes, and thus gain unauthorized access to sensitive data like
passwords.
Knowing how to analyze the data communication of a Fujitsu LX390
keyboard also enabled SySS to synthesize valid data packets which
allowed for key stroke injection attacks, which are described in the
SySS security advisory SYSS-2019-011 (see [3]).
Proof of Concept (PoC):
SySS GmbH could successfully perform sniffing attacks against the 2.4 GHz radio communication of the Fujitsu LX390 keyboard using a software-defined radio and an in-house developed software tool utilizing GNU Radio [3].
For the protocol analysis,the software tool Universal Radio Hacker [4] was used.
SySS GmbH could also perform successful sniffing attacks using another in-house developed software tool in combination with the USB radio dongle Crazyradio PA and the nrf-research-firmware by Bastille Networks Internet Security written by Marc Newlin (see [6] and [7]).
The following output of the developed PoC software tool illustrates a successful keystroke sniffing attack.

Solution:
The Fujitsu Wireless Keyboard Set LX390 reached its end-of-life (EOL) in
May 2019.
SySS recommends replacing LX390 wireless keyboard sets used in
environments with higher security demands, for instance with one of the
newer successor models LX410 or LX960.

A security vulnerability exists in the Fujitsu Wireless Keyboard Set LX390 GK381, which is caused by the program not properly encrypting 2.4 communications. An attacker could exploit the vulnerability implement replay attack. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512
Advisory ID: SYSS-2019-009 Product: Wireless Keyboard Set LX390 Manufacturer: Fujitsu Affected Version(s): Model No. GK381 Tested Version(s): Model No. GK381 Vulnerability Type: Cryptographic Issues (CWE-310) Missing Protection against Replay Attacks Risk Level: Medium Solution Status: Open (product reached end-of-life (EOL) in May 2019) Manufacturer Notification: 2019-03-22 Solution Date: - Public Disclosure: 2019-10-23 CVE Reference: CVE-2019-18199 Author of Advisory: Matthias Deeg (SySS GmbH)
Overview:
Fujitsu Wireless Keyboard Set LX390 is a wireless desktop set consisting
of a mouse and a keyboard.
The manufacturer describes the product as follows (see [1, 2]):
"The Wireless Keyboard Set LX390 is an excellent desktop solution for
users with ambition. This durable keyboard set is equipped with secure
2.4 GHz technology and plug and play technology. The elegant mouse
works on most surfaces due to its precise 1000 dpi sensor. It offers
fabulous features and ultra slim, portable design."
Due to an insecure implementation of the data communication, the
wireless keyboard LX390 is vulnerable to replay attacks.
Vulnerability Details:
SySS GmbH found out that the wireless keyboard Fujitsu LX390 is prone to replay attacks.
An attacker can simply sniff the data packets of the 2.4 GHz radio communication sent by the keyboard to the receiver (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 Fujitsu LX390 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 data communication for the password-based user authentication and thereby gets unauthorized access to the victim's system.
Proof of Concept (PoC):
SySS GmbH could successfully perform a replay attack as described in the
previous section using a software-defined radio in combination with the
software tool GNU Radio Companion.
It was also possible to perform successful replay attacks 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 written by Marc Newlin (see [3] and [4]).
SySS recommends replacing LX390 wireless keyboard sets used in
environments with higher security demands, for instance with one of the
newer successor models LX410 or LX960.

"data": "An issue was discovered on Fujitsu Wireless Keyboard Set LX390 GK381 devices. Because of the lack of proper encryption of 2.4 GHz communication, and because of password-based authentication, they are vulnerable to replay attacks. Fujitsu Wireless Keyboard Set LX390 In the device Capture-replay There is a vulnerability related to authentication bypass by.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. \n\nA security vulnerability exists in the Fujitsu Wireless Keyboard Set LX390 GK381, which is caused by the program not properly encrypting 2.4 communications. An attacker could exploit the vulnerability implement replay attack. -----BEGIN PGP SIGNED MESSAGE-----\nHash: SHA512\n\nAdvisory ID: SYSS-2019-009\nProduct: Wireless Keyboard Set LX390\nManufacturer: Fujitsu\nAffected Version(s): Model No. GK381\nTested Version(s): Model No. GK381\nVulnerability Type: Cryptographic Issues (CWE-310)\n Missing Protection against Replay Attacks\nRisk Level: Medium\nSolution Status: Open (product reached end-of-life (EOL) in May 2019)\nManufacturer Notification: 2019-03-22\nSolution Date: -\nPublic Disclosure: 2019-10-23\nCVE Reference: CVE-2019-18199\nAuthor of Advisory: Matthias Deeg (SySS GmbH)\n\n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n\nOverview:\n\nFujitsu Wireless Keyboard Set LX390 is a wireless desktop set consisting\nof a mouse and a keyboard. \n\nThe manufacturer describes the product as follows (see [1, 2]):\n\n\"The Wireless Keyboard Set LX390 is an excellent desktop solution for\nusers with ambition. This durable keyboard set is equipped with secure\n2.4 GHz technology and plug and play technology. The elegant mouse\nworks on most surfaces due to its precise 1000 dpi sensor. It offers\nfabulous features and ultra slim, portable design.\"\n\nDue to an insecure implementation of the data communication, the\nwireless keyboard LX390 is vulnerable to replay attacks. \n\n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n\nVulnerability Details:\n\nSySS GmbH found out that the wireless keyboard Fujitsu LX390 is prone to\nreplay attacks. \n\nAn attacker can simply sniff the data packets of the 2.4 GHz radio\ncommunication sent by the keyboard to the receiver (USB dongle) and\nreplay the recorded communication data at will causing the same effect\nas the original data communication. \n\nA replay attack against the keyboard can, for example, be used to gain\nunauthorized access to a computer system that is operated with a\nvulnerable Fujitsu LX390 keyboard. In this attack scenario, an attacker\nrecords the radio communication during a password-based user\nauthentication of his or her victim, for instance during a login to the\noperating system or during unlocking a screen lock. At an opportune\nmoment when the victim\u0027s computer system is unattended, the attacker\napproaches the victim\u0027s computer and replays the previously recorded\ndata communication for the password-based user authentication and\nthereby gets unauthorized access to the victim\u0027s system. \n\n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n\nProof of Concept (PoC):\n\nSySS GmbH could successfully perform a replay attack as described in the\nprevious section using a software-defined radio in combination with the\nsoftware tool GNU Radio Companion. \n\nIt was also possible to perform successful replay attacks using an\nin-house developed software tool in combination with the USB radio\ndongle Crazyradio PA and the nrf-research-firmware by Bastille Networks\nInternet Security written by Marc Newlin (see [3] and [4]). \n\nSySS recommends replacing LX390 wireless keyboard sets used in\nenvironments with higher security demands, for instance with one of the\nnewer successor models LX410 or LX960. \n\n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n\nDisclosure Timeline:\n\n2019-03-22: Vulnerability reported to manufacturer\n2019-03-23: Fujitsu confirms receipt of security advisory\n2019-04-02: Received question from manufacturer and answered them\n2019-04-11: Received further questions from manufacturer\n2019-04-18: Answered open questions and postponed disclosure date\n2019-10-08: Reminded manufacturer of the upcoming release of the\n security advisory\n2019-10-18: Discussed details of coordinated disclosure with manufacturer\n2019-10-21: Public release of security advisory\n\n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n\nReferences:\n\n[1] Product website for Fujitsu Wireless Keyboard Set LX390 (not available anymore)\n http://www.fujitsu.com/global/products/computing/peripheral/accessories/input-devices/keyboards/keyboard-lx390.html\n[2] Data sheet Fujitsu Wireless Keyboard Set LX390\n https://produktinfo.conrad.com/datenblaetter/1300000-1399999/001375431-da-01-en-FUJITSU_DESKTOP_SET_WIREL_LX390_WEISS.pdf\n[3] Product website for Crazyradio PA\n https://www.bitcraze.io/crazyradio-pa/\n[4] Bastille\u0027s nRF24 research firmware and tools\n https://github.com/BastilleResearch/nrf-research-firmware\n[5] Product website for Fujitsu Wireless Keyboard Set LX410\n https://www.fujitsu.com/global/products/computing/peripheral/accessories/input-devices/keyboards/keyboard-lx410.html\n[6] Product website for Fujitsu Wireless Keyboard Set LX960\n https://www.fujitsu.com/global/products/computing/peripheral/accessories/input-devices/keyboards/keyboard-lx960.html\n[7] SySS Security Advisory SYSS-2019-009\n https://www.syss.de/fileadmin/dokumente/Publikationen/Advisories/SYSS-2019-009.txt\n[8] SySS Responsible Disclosure Policy\n https://www.syss.de/en/responsible-disclosure-policy/\n\n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n\nCredits:\n\nThis security vulnerability was found by Matthias Deeg of SySS GmbH. \n\nE-Mail: matthias.deeg (at) syss.de\nPublic Key: https://www.syss.de/fileadmin/dokumente/Materialien/PGPKeys/Matthias_Deeg.asc\nKey fingerprint = D1F0 A035 F06C E675 CDB9 0514 D9A4 BF6A 34AD 4DAB\n\n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n\nDisclaimer:\n\nThe information provided in this security advisory is provided \"as is\" \nand without warranty of any kind.

VAR-201910-0870
Vulnerability from variot - Updated: 2024-11-23 21:36An issue was discovered on Fujitsu Wireless Keyboard Set LX390 GK381 devices. Because of the lack of proper encryption of 2.4 GHz communication, they are prone to keystroke injection attacks. Fujitsu Wireless Keyboard Set LX390 The device contains an injection vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state.
A security vulnerability exists in Fujitsu Wireless Keyboard Set LX390, which originated from a program's failure to properly encrypt 2.4 GHz communications. An attacker could use this vulnerability to send arbitrary keystrokes to the user's computer system, thereby controlling the user's computer. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512
Advisory ID: SYSS-2019-011 Product: Wireless Keyboard Set LX390 Manufacturer: Fujitsu Affected Version(s): Model No. GK381 Tested Version(s): Model No. GK381 Vulnerability Type: Cryptographic Issues (CWE-310) Keystroke Injection Vulnerability Risk Level: High Solution Status: Open (product reached end-of-life (EOL) in May 2019) Manufacturer Notification: 2019-04-01 Solution Date: - Public Disclosure: 2019-10-23 CVE Reference: CVE-2019-18200 Author of Advisory: Matthias Deeg (SySS GmbH)
Overview:
Fujitsu Wireless Keyboard Set LX390 is a wireless desktop set consisting
of a mouse and a keyboard.
The manufacturer describes the product as follows (see [1, 2]):
"The Wireless Keyboard Set LX390 is an excellent desktop solution for
users with ambition. This durable keyboard set is equipped with secure
2.4 GHz technology and plug and play technology. The elegant mouse works
on most surfaces due to its precise 1000 dpi sensor. It offers fabulous
features and ultra slim, portable design."
Due to an insecure implementation of the data communication, the
wireless keyboard LX390 is prone to keystroke injection attacks.
Vulnerability Details:
SySS GmbH found out that the wireless desktop set Fujitsu LX390 is vulnerable to keystroke injection attacks, as the used data communication is unencrypted, which is described in the SySS security advisory SYSS-2019-010 (see [3]), and unauthenticated.
By analyzing the used radio communication protocol, the so-called data whitening or data scrambling mechanism used by the 2.4 GHz radio transceiver, and its configuration, an attacker is able to send arbitrary keystrokes to a victim's computer system. In this way, an attacker can remotely take control over the victim's computer that is operated with an affected Fujitsu LX390 wireless desktop set.
The actual configuration for a specific targeted keyboard regarding the used data whitening configuration can be learned by remotely analyzing the radio communication.
In combination with the replay attack described in the SySS security advisory SYSS-2019-009 (see [4]), a keystroke injection attack allows to remotely attack computer systems with an active screen lock, for example in order to install malware when the target system is unattended.
Proof of Concept (PoC):
SySS GmbH could successfully perform keystroke injection attacks against
the Fujitsu wireless desktop set LX390 using a software-defined radio
in combination with an in-house developed software tool utilizing GNU
Radio [5].
For the protocol analysis and initial proof-of-concept attacks,
Universal Radio Hacker (URH) [6] was used.
SySS GmbH could also perform successful keystroke injection attacks
using another in-house developed software tool in combination with the
USB radio dongle Crazyradio PA and the nrf-research-firmware by Bastille
Networks Internet Security written by Marc Newlin (see [7] and [8]).
SySS recommends replacing LX390 wireless keyboard sets used in
environments with higher security demands, for instance with one of the
newer successor models LX410 or LX960.

An attacker could use this vulnerability to send arbitrary keystrokes to the user\u0027s computer system, thereby controlling the user\u0027s computer. -----BEGIN PGP SIGNED MESSAGE-----\nHash: SHA512\n\nAdvisory ID: SYSS-2019-011\nProduct: Wireless Keyboard Set LX390\nManufacturer: Fujitsu\nAffected Version(s): Model No. GK381\nTested Version(s): Model No. GK381\nVulnerability Type: Cryptographic Issues (CWE-310)\n Keystroke Injection Vulnerability\nRisk Level: High\nSolution Status: Open (product reached end-of-life (EOL) in May 2019)\nManufacturer Notification: 2019-04-01\nSolution Date: -\nPublic Disclosure: 2019-10-23 \nCVE Reference: CVE-2019-18200\nAuthor of Advisory: Matthias Deeg (SySS GmbH)\n\n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n\nOverview:\n\nFujitsu Wireless Keyboard Set LX390 is a wireless desktop set consisting\nof a mouse and a keyboard. \n\nThe manufacturer describes the product as follows (see [1, 2]):\n\n\"The Wireless Keyboard Set LX390 is an excellent desktop solution for\nusers with ambition. This durable keyboard set is equipped with secure\n2.4 GHz technology and plug and play technology. The elegant mouse works\non most surfaces due to its precise 1000 dpi sensor. It offers fabulous\nfeatures and ultra slim, portable design.\"\n\nDue to an insecure implementation of the data communication, the\nwireless keyboard LX390 is prone to keystroke injection attacks. \n\n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n\nVulnerability Details:\n\nSySS GmbH found out that the wireless desktop set Fujitsu LX390 is\nvulnerable to keystroke injection attacks, as the used data\ncommunication is unencrypted, which is described in the SySS security\nadvisory SYSS-2019-010 (see [3]), and unauthenticated. \n\nBy analyzing the used radio communication protocol, the so-called data\nwhitening or data scrambling mechanism used by the 2.4 GHz radio\ntransceiver, and its configuration, an attacker is able to send\narbitrary keystrokes to a victim\u0027s computer system. In this way, an\nattacker can remotely take control over the victim\u0027s computer that is\noperated with an affected Fujitsu LX390 wireless desktop set. \n\nThe actual configuration for a specific targeted keyboard regarding the\nused data whitening configuration can be learned by remotely analyzing\nthe radio communication. \n\nIn combination with the replay attack described in the SySS security\nadvisory SYSS-2019-009 (see [4]), a keystroke injection attack allows to\nremotely attack computer systems with an active screen lock, for example\nin order to install malware when the target system is unattended. \n\n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n\nProof of Concept (PoC):\n\nSySS GmbH could successfully perform keystroke injection attacks against\nthe Fujitsu wireless desktop set LX390 using a software-defined radio\nin combination with an in-house developed software tool utilizing GNU\nRadio [5]. \n\nFor the protocol analysis and initial proof-of-concept attacks,\nUniversal Radio Hacker (URH) [6] was used. \n\nSySS GmbH could also perform successful keystroke injection attacks\nusing another in-house developed software tool in combination with the\nUSB radio dongle Crazyradio PA and the nrf-research-firmware by Bastille\nNetworks Internet Security written by Marc Newlin (see [7] and [8]). \n\nSySS recommends replacing LX390 wireless keyboard sets used in\nenvironments with higher security demands, for instance with one of the\nnewer successor models LX410 or LX960. \n\n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n\nDisclosure Timeline:\n\n2019-04-01: Vulnerability reported to manufacturer\n2019-04-02: Fujitsu confirms receipt of security advisory and asks\n questions regarding the reported security issue;\n answered open questions\n2019-04-11: Received further questions from manufacturer\n2019-04-18: Answered open questions and postponed disclosure date\n2019-10-08: Reminded manufacturer of the upcoming release of the\n security advisory\n2019-10-18: Discussed details of coordinated disclosure with\n manufacturer\n2019-10-21: Public release of security advisory\n\n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n\nReferences:\n\n[1] Product website for Fujitsu Wireless Keyboard Set LX390 (not available anymore)\n https://www.fujitsu.com/global/products/computing/peripheral/accessories/input-devices/keyboards/keyboard-lx390.html\n[2] Data sheet Fujitsu Wireless Keyboard Set LX390\n https://produktinfo.conrad.com/datenblaetter/1300000-1399999/001375431-da-01-en-FUJITSU_DESKTOP_SET_WIREL_LX390_WEISS.pdf\n[3] SySS Security Advisory SYSS-2019-010\n https://www.syss.de/fileadmin/dokumente/Publikationen/Advisories/SYSS-2019-010.txt\n[4] SySS Security Advisory SYSS-2019-009\n https://www.syss.de/fileadmin/dokumente/Publikationen/Advisories/SYSS-2019-009.txt\n[5] GNU Radio\n https://www.gnuradio.org/\n[6] Universal Radio Hacker (URH)\n https://github.com/jopohl/urh\n[7] Product website for Crazyradio PA\n https://www.bitcraze.io/crazyradio-pa/\n[8] Bastille\u0027s nRF24 research firmware and tools\n https://github.com/BastilleResearch/nrf-research-firmware\n[9] Product website for Fujitsu Wireless Keyboard Set LX410\n https://www.fujitsu.com/global/products/computing/peripheral/accessories/input-devices/keyboards/keyboard-lx410.html\n[10] Product website for Fujitsu Wireless Keyboard Set LX960\n https://www.fujitsu.com/global/products/computing/peripheral/accessories/input-devices/keyboards/keyboard-lx960.html\n[11] SySS Security Advisory SYSS-2019-011\n https://www.syss.de/fileadmin/dokumente/Publikationen/Advisories/SYSS-2019-011.txt\n[12] SySS Responsible Disclosure Policy\n https://www.syss.de/en/responsible-disclosure-policy/\n\n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n\nCredits:\n\nThis security vulnerability was found by Matthias Deeg of SySS GmbH. \n\nE-Mail: matthias.deeg (at) syss.de\nPublic Key: https://www.syss.de/fileadmin/dokumente/PGPKeys/Matthias_Deeg.asc\nKey fingerprint = D1F0 A035 F06C E675 CDB9 0514 D9A4 BF6A 34AD 4DAB\n\n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n\nDisclaimer:\n\nThe information provided in this security advisory is provided \"as is\" \nand without warranty of any kind.
