  "summary" : "Withdrawn Advisory: Kanister vulnerable to cluster-level privilege escalation",
  "details" : "# Withdrawn Advisory\n\nThis advisory has been withdrawn because the vulnerability does not affect a released Go package. For more information, see github/advisory-database/issues/5029.\n\n# Original Advisory\n\n### Summary\nThis advisory affects the Kanister helm charts and not the go package\n\n### Details\nThe kanister has a deployment called default-kanister-operator, which is bound with a ClusterRole called edit via ClusterRoleBinding(https://github.com/kanisterio/kanister/blob/master/helm/kanister-operator/templates/rbac.yaml#L49). The \"edit\" ClusterRole is one of Kubernetes default-created ClusterRole, and it have create/patch/udpate verbs of daemonset resources, create verb of serviceaccount/token resources, and impersonate verb of serviceaccounts resources. If a malicious user can access the worker node which has this component, he/she can:\n\nFor the create/patch/update verbs of daemonset resources, the malicious user can abuse it to create or modify a set of Pods to mount a high-privilege service account (e.g., the cluster-admin service account). After that, he/she can abuse the high-privilege SA token of created Pod to take over the whole cluster.\n\nFor the create verb of serviceaccount/token resources, a malicious user can abuse this permission to generate new Service Account tokens and use them to operate with high-privilege roles, such as cluster administrators. These tokens can be used to access and manipulate any resources within the cluster.\n\nFor the impersonate verb of serviceaccounts resources, a malicious user can impersonate high-privilege Service Accounts, thereby gaining access to roles such as cluster administrators. This enables the attacker to perform all actions that the high-privilege account can, including creating, modifying, and deleting critical resources within the cluster.\n\n\n### PoC\nWe have discussed in the \"Details\" section\n\n### Impact\nPrivilege escalation\n\n### Mitigation\n\nCurrently kanister helm chart provides rbac.create flag (true by default), which controls whether the rbac rules for kanister service account will be created https://github.com/kanisterio/kanister/blob/master/helm/kanister-operator/values.yaml#L17\nIf this value set to false, the user needs to create rbac rules themselves and they can limit the role bindings for kanister service account, for example scope it to specific namespace.\nService account can also be configured via helm https://github.com/kanisterio/kanister/blob/master/helm/kanister-operator/values.yaml#L19\n",
