Attack vector: auth-bypass
Category: vulnerability-disclosure
Severity: Medium
CVE: CVE-2023-30617

### 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 ### References None
