CVE-2022-43757 [CRITICAL] Plaintext storage of sensitive data in Rancher API and cluster.management.cattle.io objects
Plaintext storage of sensitive data in Rancher API and cluster.management.cattle.io objects
### Impact
This issue affects Rancher versions from 2.5.0 up to and including 2.5.16, from 2.6.0 up to and including 2.6.9 and 2.7.0. It was discovered that the security advisory CVE-2021-36782 (GHSA-g7j7-h4q8-8w2f), previously released by Rancher, missed addressing some sensitive fields, secret tokens, encryption keys, and SSH keys that were still being stored in plaintext directly on Kubernetes objects like `Clusters`.
The exposed credentials are visible in Rancher to authenticated `Cluster Owners`, `Cluster Members`, `Project Owners` and `Project Members` of that cluster on the endpoints:
- `/v1/management.cattle.io.cluster`
- `/v1/management.cattle.io.clustertemplaterevisions`
