Detailsinfo

A vulnerability was found in Clusternet up to 0.15.1. It has been classified as problematic. Affected is some unknown processing. The manipulation with an unknown input leads to a random values vulnerability. CWE is classifying the issue as CWE-330. The product uses insufficiently random numbers or values in a security context that depends on unpredictable numbers. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Clusternet is a general-purpose system for controlling Kubernetes clusters across different environments. An issue in clusternet prior to version 0.15.2 can be leveraged to lead to a cluster-level privilege escalation. The clusternet has a deployment called `cluster-hub` inside the `clusternet-system` Kubernetes namespace, which runs on worker nodes randomly. The deployment has a service account called `clusternet-hub`, which has a cluster role called `clusternet:hub` via cluster role binding. The `clusternet:hub` cluster role has `"*" verbs of "*.*"` resources. Thus, if a malicious user can access the worker node which runs the clusternet, they can leverage the service account to do malicious actions to critical system resources. For example, the malicious user can leverage the service account to get ALL secrets in the entire cluster, resulting in cluster-level privilege escalation. Version 0.15.2 contains a fix for this issue.

The weakness was published 04/24/2023 as GHSA-833c-xh79-p429. The advisory is available at github.com. This vulnerability is traded as CVE-2023-30622 since 04/13/2023. The technical details are unknown and an exploit is not available. This vulnerability is assigned to T1600.001 by the MITRE ATT&CK project.
