CVSSv4.0: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green

Exploitation vector: Remote access
Exploit availability: No public exploit available
Vulnerable software:
kubeclient
Software vendor:
ManageIQ

Description

The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exists due to the way kubeclient parses kubeconfig files. When the kubeconfig file does not configure custom CA to verify certs, kubeclient ends up accepting any certificate (it wrongly returns VERIFY_NONE). A remote attacker can perform MitM attack.


Remediation

Install updates from vendor's website.
