Severity ?
7.5 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Summary
An issue was discovered in Barrier before 2.3.4. The barriers component (aka the server-side implementation of Barrier) does not correctly close file descriptors for established TCP connections. An unauthenticated remote attacker can thus cause file descriptor exhaustion in the server process, leading to denial of service.

Severity ?
8.8 (High) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
An issue was discovered in Barrier before 2.4.0. The barriers component (aka the server-side implementation of Barrier) does not sufficiently verify the identify of connecting clients. Clients can thus exploit weaknesses in the provided protocol to cause denial-of-service or stage further attacks that could lead to information leaks or integrity corruption.

Vulnerability from fkie_nvd
Published

Modified
2024-11-21 06:27
Severity ?
8.2 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:N
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.

CVE-2021-42075 (GCVE-0-2021-42075)
Vulnerability from cvelistv5
Published
2021-11-08 03:55

  • n/a
Summary
An issue was discovered in Barrier before 2.3.4. The barriers component (aka the server-side implementation of Barrier) does not correctly close file descriptors for established TCP connections. An unauthenticated remote attacker can thus cause file descriptor exhaustion in the server process, leading to denial of service.

CVE-2021-42073 (GCVE-0-2021-42073)
Vulnerability from cvelistv5
Published

Modified
2024-08-04 03:22
Severity ?
CWE
  • n/a
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.

Summary
An issue was discovered in Barrier before 2.4.0. The barriers component (aka the server-side implementation of Barrier) does not sufficiently verify the identify of connecting clients. Clients can thus exploit weaknesses in the provided protocol to cause denial-of-service or stage further attacks that could lead to information leaks or integrity corruption.
