A Cleartext Storage of Sensitive Information vulnerability in SUSE Rancher allows authenticated Cluster Owners, Cluster Members, Project Owners, Project Members and User Base to use the Kubernetes API to retrieve plaintext version of sensitive data. This issue affects: SUSE Rancher Rancher versions prior to 2.5.16; Rancher versions prior to 2.6.7.
The product stores sensitive information in cleartext within a resource that might be accessible to another control sphere.
| Name | Vendor | Start Version | End Version |
|---|---|---|---|
| Rancher | Suse | 2.5.0 (including) | 2.5.16 (excluding) |
| Rancher | Suse | 2.6.0 (including) | 2.6.7 (excluding) |
Because the information is stored in cleartext (i.e., unencrypted), attackers could potentially read it. Even if the information is encoded in a way that is not human-readable, certain techniques could determine which encoding is being used, then decode the information. When organizations adopt cloud services, it can be easier for attackers to access the data from anywhere on the Internet. In some systems/environments such as cloud, the use of “double encryption” (at both the software and hardware layer) might be required, and the developer might be solely responsible for both layers, instead of shared responsibility with the administrator of the broader system/environment.
