KubeView vulnerable to full cluster takeover due to improper authentication

CVE-2022-45933 → View on GitHub ↗ View on CVE.org ↗ View on NVD ↗

Description

KubeView through 0.1.31 allows attackers to obtain control of a Kubernetes cluster because api/scrape/kube-system does not require authentication, and retrieves certificate files that can be used for authentication as kube-admin. NOTE: the vendor's position is that KubeView was a "fun side project and a learning exercise," and not "very secure."

CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
