Summary
Withdrawn Advisory: Kanister vulnerable to cluster-level privilege escalation
Details

Withdrawn Advisory

This advisory has been withdrawn because the vulnerability does not affect a released Go package. For more information, see github/advisory-database/issues/5029.

Original Advisory

Summary

This advisory affects the Kanister helm charts and not the go package

Details

The 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:

For 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.

For 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.

For 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.

Impact

Privilege escalation

Mitigation

Currently 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 If 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. Service account can also be configured via helm https://github.com/kanisterio/kanister/blob/master/helm/kanister-operator/values.yaml#L19

GHSA-H2W9-5QX3-FRQQ

Vulnerability from github – Published: 2026-08-12 21:31 – Updated: 2026-09-05 15:30
VLAI
Details

A flaw was found in the cluster-curator-controller component. A local user, by creating a ClusterCurator resource with a specific naming convention, can trigger the creation of a cluster-scoped ClusterRoleBinding. This allows the user to escalate their privileges from namespace-local access to cluster-wide control. This privilege escalation grants broad permissions, including the ability to access and manipulate secrets, manage cluster actions, and delete hosted clusters or node pools.

  "details": "A flaw was found in the cluster-curator-controller component. A local user, by creating a ClusterCurator resource with a specific naming convention, can trigger the creation of a cluster-scoped ClusterRoleBinding. This allows the user to escalate their privileges from namespace-local access to cluster-wide control. This privilege escalation grants broad permissions, including the ability to access and manipulate secrets, manage cluster actions, and delete hosted clusters or node pools.",

Details

The vCenter Server contains a local privilege escalation vulnerability due to the way it handles session tokens. A malicious actor with non-administrative user access on vCenter Server host may exploit this issue to escalate privileges to Administrator on the vSphere Client (HTML5) or vCenter Server vSphere Web Client (FLEX/Flash).

Mitigation MIT-1
Architecture and Design Operation

Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.

Mitigation MIT-48
Architecture and Design

Strategy: Separation of Privilege

Follow the principle of least privilege when assigning access rights to entities in a software system.

Mitigation MIT-49
Architecture and Design

Strategy: Separation of Privilege

Consider following the principle of separation of privilege. Require multiple conditions to be met before permitting access to a system resource.

CAPEC-122: Privilege Abuse

An adversary is able to exploit features of the target that should be reserved for privileged users or administrators but are exposed to use by lower or non-privileged accounts. Access to sensitive information and functionality must be controlled to ensure that only authorized users are able to access these resources.

CAPEC-233: Privilege Escalation

An adversary exploits a weakness enabling them to elevate their privilege and perform an action that they are not supposed to be authorized to perform.

CAPEC-58: Restful Privilege Elevation

An adversary identifies a Rest HTTP (Get, Put, Delete) style permission method allowing them to perform various malicious actions upon server data due to lack of access control mechanisms implemented within the application service accepting HTTP messages.
