NewStart CGSL MAIN 6.06 (SP) : cloud-init Multiple Vulnerabilities (NS-SA-2026-0026)
high Nessus Plugin ID 301196
Synopsis
The remote NewStart CGSL host is affected by multiple vulnerabilities.Description
The remote NewStart CGSL host, running version MAIN 6.06 (SP), has cloud-init packages installed that are affected by multiple vulnerabilities:- 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. (CVE-2018-10896)
- 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.
(CVE-2020-8631)
- 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. (CVE-2020-8632)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
Solution
Upgrade the vulnerable CGSL cloud-init packages. Note that updated packages may not be available yet. Please contact ZTE for more information.See Also
