CVE-2018-10896 (GCVE-0-2018-10896)
Vulnerability from cvelistv5
Published
2018-08-01 17:00
Modified
2024-08-05 07:54
Severity ?
4.6 (Medium) - CVSS:3.0/AV:L/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N
CWE
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.
