NewStart CGSL MAIN 6.02 : cloud-init Multiple Vulnerabilities (NS-SA-2021-0062)

medium Nessus Plugin ID 147272

Language:

Synopsis

The remote machine is affected by multiple vulnerabilities.

Description

The remote NewStart CGSL host, running version MAIN 6.02, has cloud-init packages installed that are affected by multiple vulnerabilities:

 - 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)

 - 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)

Note that Nessus has not tested for this issue 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.
