| CVE | 摘要 | 來源 | 最高 CVSS | EPSS % | 公開時間 | 更新時間 |
|---|---|---|---|---|---|---|
| CVE-2024-6174 | 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. | [email protected] | 8.8 | 0.21% | 2025-06-26 | 2026-06-17 |
| CVE-2024-11584 | 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. | [email protected] | 5.9 | 0.10% | 2025-06-26 | 2026-06-17 |
| CVE-2023-1786 | Sensitive data could be exposed in logs of cloud-init before version 23.1.2. An attacker could use this information to find hashed passwords and possibly escalate their privilege. | [email protected] | 5.5 | 0.27% | 2023-04-26 | 2026-06-17 |
| CVE-2022-2084 | Sensitive data could be exposed in world readable logs of cloud-init before version 22.3 when schema failures are reported. This leak could include hashed passwords. | [email protected] | 5.5 | 0.24% | 2023-04-19 | 2026-06-17 |
| CVE-2021-3429 | 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. | [email protected] | 5.5 | 0.22% | 2023-04-19 | 2026-06-17 |
| CVE-2020-8632 | In cloud-init through 19.4, rand_user_password in cloudinit/config/cc_set_passwords.py has a small default pwlen value, which makes it easier for attackers to guess passwords. | [email protected] | 5.5 | 0.37% | 2020-02-05 | 2026-06-16 |
| CVE-2020-8631 | 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. | [email protected] | 5.5 | 0.44% | 2020-02-05 | 2026-06-16 |
| CVE-2012-6639 | An privilege elevation vulnerability exists in Cloud-init before 0.7.0 when requests to an untrusted system are submitted for EC2 instance data. | [email protected] | 8.8 | 2.05% | 2019-11-25 | 2026-06-16 |
| CVE-2018-10896 | 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. | [email protected] | 7.1 | 0.35% | 2018-08-01 | 2026-06-16 |
