Summary
An issue was discovered in Barrier before 2.4.0. An attacker can enter an active session state with the barriers component (aka the server-side implementation of Barrier) simply by supplying a client label that identifies a valid client configuration. This label is "Unnamed" by default but could instead be guessed from hostnames or other publicly available information. In the active session state, an attacker can capture input device events from the server, and also modify the clipboard content on the server.

OPENSUSE-SU-2021:1498-1
Vulnerability from csaf_opensuse - Published: 2021-11-22 11:06 - Updated: 2021-11-22 11:06Summary
Security update for barrier
Severity
Moderate
Notes
Title of the patch: Security update for barrier
Description of the patch: This update for barrier fixes the following issues:
Updated to version 2.4.0:
Barrier now supports client identity verification (fixes CVE-2021-42072,
CVE-2021-42073).
Previously a malicious client could connect to Barrier server without any
authentication and send application-level messages. This made the attack
surface of Barrier significantly larger. Additionally, in case the malicious
client got possession of a valid screen name by brute forcing or other means
it could modify the clipboard contents of the server.
To support seamless upgrades from older versions of Barrier this is
currently disabled by default. The feature can be enabled in the settings
dialog. If enabled, older clients of Barrier will be rejected.
Barrier now uses SHA256 fingerprints for establishing security of encrypted
SSL connections. After upgrading client to new version the existing server
fingerprint will need to be approved again. Client and server will show both
SHA1 and SHA256 server fingerprints to allow interoperability with older
versions of Barrier.
Bugfixes:
* Fixed build failure on mips*el and riscv64 architecture.
* Barrier no longer uses openssl CLI tool for any operations and hooks into
the openssl library directly.
* More X11 clipboard MIME types have been mapped to corresponding converters
(#344).
* Fixed setup of multiple actions associated with a hotkey.
* Fixed setup of hotkeys with special characters such as comma and semicolon
(#778).
* Fixed transfer of non-ASCII characters coming from a Windows server in
certain cases (#527).
* Barrier will now regenerate server certificate if it's invalid instead of
failing to launch (#802)
* Added support for additional keys on Sun Microsystems USB keyboards (#784).
* Updated Chinese translation.
* Updated Slovak translation.
* Theme icons are now preferred to icons distributed together with Barrier
(#471).
Features:
* Added --drop-target option that improves drag and drop support on Windows
when Barrier is being run as a portable app.
* The --enable-crypto command line option has been made the default to reduce
chances of accidental security mishaps when configuring Barrier from command
line. A new --disable-crypto command line option has been added to
explicitly disable encryption.
* Added support for randomart images for easier comparison of SSL certificate
fingerprints. The algorithm is identical to what OpenSSH uses.
* Implemented a configuration option for Server GUI auto-start.
* Made it possible to use keyboard instead of mouse to modify screen layout.
* Added support for keyboard backlight media keys
* Added support for Eisu_toggle and Muhenkan keys
* Added --profile-dir option that allows to select custom profile directory.

OPENSUSE-SU-2021:1595-1
Vulnerability from csaf_opensuse - Published: 2021-12-18 23:06 - Updated: 2021-12-18 23:06Summary
Security update for barrier
Severity
Moderate
Notes
Title of the patch: Security update for barrier
Description of the patch: This update for barrier fixes the following issues:
Updated to version 2.4.0:
Barrier now supports client identity verification (fixes CVE-2021-42072,
CVE-2021-42073).
Previously a malicious client could connect to Barrier server without any
authentication and send application-level messages. This made the attack
surface of Barrier significantly larger. Additionally, in case the malicious
client got possession of a valid screen name by brute forcing or other means
it could modify the clipboard contents of the server.
To support seamless upgrades from older versions of Barrier this is
currently disabled by default. The feature can be enabled in the settings
dialog. If enabled, older clients of Barrier will be rejected.
Barrier now uses SHA256 fingerprints for establishing security of encrypted
SSL connections. After upgrading client to new version the existing server
fingerprint will need to be approved again. Client and server will show both
SHA1 and SHA256 server fingerprints to allow interoperability with older
versions of Barrier.
Bugfixes:
* Fixed build failure on mips*el and riscv64 architecture.
* Barrier no longer uses openssl CLI tool for any operations and hooks into
the openssl library directly.
* More X11 clipboard MIME types have been mapped to corresponding converters
(#344).
* Fixed setup of multiple actions associated with a hotkey.
* Fixed setup of hotkeys with special characters such as comma and semicolon
(#778).
* Fixed transfer of non-ASCII characters coming from a Windows server in
certain cases (#527).
* Barrier will now regenerate server certificate if it's invalid instead of
failing to launch (#802)
* Added support for additional keys on Sun Microsystems USB keyboards (#784).
* Updated Chinese translation.
* Updated Slovak translation.
* Theme icons are now preferred to icons distributed together with Barrier
(#471).
Features:
* Added --drop-target option that improves drag and drop support on Windows
when Barrier is being run as a portable app.
* The --enable-crypto command line option has been made the default to reduce
chances of accidental security mishaps when configuring Barrier from command
line. A new --disable-crypto command line option has been added to
explicitly disable encryption.
* Added support for randomart images for easier comparison of SSL certificate
fingerprints. The algorithm is identical to what OpenSSH uses.
* Implemented a configuration option for Server GUI auto-start.
* Made it possible to use keyboard instead of mouse to modify screen layout.
* Added support for keyboard backlight media keys
* Added support for Eisu_toggle and Muhenkan keys
* Added --profile-dir option that allows to select custom profile directory.

Summary
An issue was discovered in Barrier before 2.4.0. An attacker can enter an active session state with the barriers component (aka the server-side implementation of Barrier) simply by supplying a client label that identifies a valid client configuration. This label is "Unnamed" by default but could instead be guessed from hostnames or other publicly available information. In the active session state, an attacker can capture input device events from the server, and also modify the clipboard content on the server.
