1) Incorrect authorization

EUVDB-ID: #VU75445

Risk: Medium

CVSSv4.0: 6.2 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2023-26484

CWE-ID: CWE-863 - Incorrect Authorization

Exploit availability: No

Description

The vulnerability allows a remote user to compromise the cluster.

The vulnerability exists due to incorrect authorization, which allows the virt-handler service account to modify all node specs. A remote user can elevate privileges beyond the node and gain access to the whole cluster.

Mitigation

Update the affected package kubevirt, virt-api-container, virt-controller-container, virt-handler-container, virt-launcher-container, virt-libguestfs-tools-container, virt-operator-container to the latest version.
