Advisory ID: SYSS-2016-074
Product: Wireless Presenter R400
Manufacturer: Logitech
Affected Version(s): Model R-R0008
Tested Version(s): Model R-R0008
Vulnerability Type: Insufficient Verification of Data Authenticity (CWE-345)
Keystroke Injection Vulnerability
Risk Level: High
Solution Status: Open
Manufacturer Notification: 2016-08-12
Solution Date: -
Public Disclosure: 2016-10-12
CVE Reference: Not yet assigned
Authors of Advisory: Matthias Deeg (SySS GmbH)



Overview:

Logitech R400 is a wireless presenter using 2.4 GHz radio communication.

The manufacturer describes the product as follows (see [1]):

"Intuitive controls and red laser pointer make presentations a snap,
even in the darkest auditoriums."

Due to unencrypted and unauthenticated data communication, the wireless
presenter Logitech R400 is prone to keystroke injection attacks.



Vulnerability Details:

The SySS GmbH found out that the wireless presenter Logitech R400 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
a Logitech R400 wireless presenter.



Proof of Concept (PoC):

The SySS GmbH could successfully perform keystroke injection attacks
against the wireless presenter Logitech R400 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
(see [2] and [3]).

The following output of the developed proof-of-concept software tool
illustrates a successful attack:

[FD] [SYSS-2016-075] Targus Multimedia Presentation Remote - Insufficient Verification of Data Authenticity (CWE-345), Mouse Spoofing Attack

[Matthias Deeg]

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA512

Advisory ID: SYSS-2016-075
Product: Multimedia Presentation Remote
Manufacturer: Targus
Affected Version(s): Model AMP09-EU
Tested Version(s): Model AMP09-EU
Vulnerability Type: Insufficient Verification of Data Authenticity (CWE-345)
Mouse Spoofing Attack
Risk Level: Medium
Solution Status: Open
Manufacturer Notification: 2016-08-16
Solution Date: -
Public Disclosure: 2016-10-12
CVE Reference: Not yet assigned
Authors of Advisory: Matthias Deeg (SySS GmbH)



Overview:

Targus Multimedia Presentation Remote is a wireless presenter using 2.4
GHz radio communication.

The manufacturer describes the product as follows (see [1]):

"Don't fumble around with wires or fuss over the computer; present like
a professional and control your computer remotely, using just one
device - the Targus Multi Media Presentation Remote with Cursor Control.
Thanks to the remote's 2.4GHz cordless technology, you can access
programmes, launch the internet, adjust volumes and play music and
videos, all from up to 15 metres away."

Due to unencrypted and unauthenticated mouse data communication, the
wireless presenter Targus Multimedia Presentation Remote is vulnerable
to mouse spoofing attacks.



Vulnerability Details:

The SySS GmbH found out that the wireless presenter Targus Multimedia
Presentation Remote is prone to mouse spoofing attacks, as the
cursor control data communication is unencrypted and unauthenticated.

An attacker can analyze the unencrypted cursor control 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 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 presenter Targus
Multimedia Presentation Remote. 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 presenter Targus Multimedia
Presentation Remote 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 (see [2]
and [3]).

A proof-of-concept mouse spoofing attack that also applies to the
wireless presenter Targus Multimedia Presentation Remote 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.

[FD] New OpenSSL double-free and invalid free vulnerabilities in X509 parsing

[Guido Vranken]

These vulnerabilities were found in the latest OpenSSL (1.1.0b).
Triggering these vulnerabilities is not trivial -- they rely on memory
shortages (malloc/realloc failures) or failing to acquire a thread
lock while the X509 data is being parsed. Possibly exploitation can be
achieved by exploiting a memory leak/accumulation (such as the
recently discovered CVE-2016-6304). Proof of concepts and more
extensive commentary at the link below.
