概要

Impact

Attacker that has gain root privilege of the node that kruise-daemon run , can leverage the kruise-daemon pod to list all secrets in the entire cluster. After that, attackers can leverage the "captured" secrets (e.g. the kruise-manager service account token) to gain extra privilege such as pod modification.

Workarounds

For users that do not require imagepulljob functions, they can modify kruise-daemon-role to drop the cluster level secret get/list privilege

Patches

For users who're using v0.8.x ~ v1.2.x, please update the v1.3.1 For users who're using v1.3, please update the v1.3.1 For users who're using v1.4, please update the v1.4.1 For users who're using v1.5, please update the v1.5.2

NVD の説明

Kruise provides automated management of large-scale applications on Kubernetes. Starting in version 0.8.0 and prior to versions 1.3.1, 1.4.1, and 1.5.2, an attacker who has gained root privilege of the node that kruise-daemon run can leverage the kruise-daemon pod to list all secrets in the entire cluster. After that, the attacker can leverage the "captured" secrets (e.g. the kruise-manager service account token) to gain extra privileges such as pod modification. Versions 1.3.1, 1.4.1, and 1.5.2 fix this issue. A workaround is available. For users that do not require imagepulljob functions, they can modify kruise-daemon-role to drop the cluster level secret get/list privilege.
