Which Cloud-Init flaws are most likely to be used?
Ranked by the latest exploit-likelihood forecast: the chance each flaw is used in an attack in the next 30 days. A high severity score on its own doesn't tell you that. Flaws shared by many other makers' products are left out.
- 2.0%CVE-2012-6639High
An privilege elevation vulnerability exists in Cloud-init before 0.7.0 when requests to an untrusted system are submitted for EC2 instance data.
- 0.4%CVE-2020-8631Medium
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.
- 0.4%CVE-2020-8632Medium
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.
- 0.4%CVE-2018-10896High
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.
- 0.3%CVE-2024-6174High
When a non-x86 platform is detected, cloud-init grants root access to a hardcoded url with a local IP address.
- 0.3%CVE-2023-1786Medium
Sensitive data could be exposed in logs of cloud-init before version 23.1.2.
- 0.2%CVE-2022-2084Medium
Sensitive data could be exposed in world readable logs of cloud-init before version 22.3 when schema failures are reported.
- 0.2%CVE-2021-3429Medium
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.
- 0.1%CVE-2024-11584Medium
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.
