Vulnerability from nvd – Published: 2025-06-26 09:15 – Updated: 2025-06-26 17:38

Summary

When a non-x86 platform is detected, cloud-init grants root access to a hardcoded url with a local IP address. To prevent this, cloud-init default configurations disable platform enumeration.

Severity ?

8.8 (High)

CVE-2024-11584 (GCVE-0-2024-11584)

Vulnerability from nvd – Published: 2025-06-26 09:25 – Updated: 2025-06-26 19:14

Summary

cloud-init through 25.1.2 includes the systemd socket unit cloud-init-hotplugd.socket with default SocketMode that grants 0666 permissions, making it world-writable. This is used for the "/run/cloud-init/hook-hotplug-cmd" FIFO. An unprivileged user could trigger hotplug-hook commands.

Severity ?

5.9 (Medium)

CVE-2021-3429 (GCVE-0-2021-3429)

Vulnerability from nvd – Published: 2023-04-19 21:42 – Updated: 2025-02-05 14:44

Title

sensitive data exposure in cloud-init logs

Summary

When instructing cloud-init to set a random password for a new user account, versions before 21.2 would write that password to the world-readable log file /var/log/cloud-init-output.log. This could allow a local user to log in as another user.

Severity ?

5.5 (Medium)

CVE-2018-10896 (GCVE-0-2018-10896)

Vulnerability from nvd – Published: 2018-08-01 17:00 – Updated: 2024-08-05 07:54

Summary

The default cloud-init configuration, in cloud-init 0.6.2 and newer, included "ssh_deletekeys: 0", disabling cloud-init's deletion of ssh host keys. In some environments, this could lead to instances created by cloning a golden master or template system, sharing ssh host keys, and being able to impersonate one another or conduct man-in-the-middle attacks.

Severity ?

4.6 (Medium)

Vulnerability from cvelistv5 – Published: 2025-06-26 09:25 – Updated: 2025-06-26 19:14

Summary

cloud-init through 25.1.2 includes the systemd socket unit cloud-init-hotplugd.socket with default SocketMode that grants 0666 permissions, making it world-writable. This is used for the "/run/cloud-init/hook-hotplug-cmd" FIFO. An unprivileged user could trigger hotplug-hook commands.

Severity ?

CVE-2024-6174 (GCVE-0-2024-6174)

Vulnerability from cvelistv5 – Published: 2025-06-26 09:15 – Updated: 2025-06-26 17:38

Summary

When a non-x86 platform is detected, cloud-init grants root access to a hardcoded url with a local IP address. To prevent this, cloud-init default configurations disable platform enumeration.

Severity ?

8.8 (High)

Vulnerability from cvelistv5 – Published: 2023-04-19 21:42 – Updated: 2025-02-05 14:44

Title

sensitive data exposure in cloud-init logs

Summary

When instructing cloud-init to set a random password for a new user account, versions before 21.2 would write that password to the world-readable log file /var/log/cloud-init-output.log. This could allow a local user to log in as another user.

CVE-2020-8631 (GCVE-0-2020-8631)

Vulnerability from cvelistv5 – Published: 2020-02-05 13:39 – Updated: 2024-08-04 10:03

Summary

cloud-init through 19.4 relies on Mersenne Twister for a random password, which makes it easier for attackers to predict passwords, because rand_str in cloudinit/util.py calls the random.choice function.

Severity ?

No CVSS data available.

CVE-2018-10896 (GCVE-0-2018-10896)

Vulnerability from cvelistv5 – Published: 2018-08-01 17:00 – Updated: 2024-08-05 07:54

Summary

The default cloud-init configuration, in cloud-init 0.6.2 and newer, included "ssh_deletekeys: 0", disabling cloud-init's deletion of ssh host keys. In some environments, this could lead to instances created by cloning a golden master or template system, sharing ssh host keys, and being able to impersonate one another or conduct man-in-the-middle attacks.
