CVE-2024-52282

A Exposure of Sensitive Information to an Unauthorized Actor vulnerability in SUSE rancher allowing any users with GET access to the Rancher Manager Apps Catalog to read any sensitive information that are contained within the Apps’ values. Additionally, the same information leaks into auditing logs when the audit level is set to equal or above 2.

This issue affects rancher: from 2.8.0 before 2.8.10, from 2.9.0 before 2.9.4.

A Exposure of Sensitive Information to an Unauthorized Actor vulnerability in SUSE rancher allowing any users with GET access to the Rancher Manager Apps Catalog to read any sensitive information that are contained within the Apps’ values. Additionally, the same information leaks into auditing logs when the audit level is set to equal or above 2.

This issue affects rancher: from 2.8.0 before 2.8.10, from 2.9.0 before 2.9.4.

Impact

A vulnerability has been identified within Rancher Manager whereby applications installed via Rancher Manager Apps Catalog store their Helm values directly into the Apps Custom Resource Definition, resulting in any users with GET access to it to be able to read any sensitive information that are contained within the Apps’ values. Additionally, the same information leaks into auditing logs when the audit level is set to equal or above 2.

Application charts without sensitive data are not affected by this vulnerability. This vulnerability impacts any Helm applications installed on a Rancher Manager cluster, regardless of it being installed via the Marketplace or using the helm cli.

Please consult the associated MITRE ATT&CK - Technique - Exploitation for Privilege Escalation for further information about this category of attack.

Patches

Patched versions include Rancher Manager 2.9.5 and 2.8.10. The fix ensures that all Helm values for each App are stored as Kubernetes Secrets. After the upgrade, users are recommended to rotate passwords and secrets that may have been leaked while using the affected versions.

Workarounds

No workarounds are available, therefore users are advised to upgrade to a patched version of Rancher Manager. For deployments that can’t be upgraded in a timely fashion, admins are advised to limit the impact by reducing the amount of users who can get or list the Apps’ CRD. Additionally, the same applies to the auditing logs if the Rancher Manager has audit logs enabled and set to level 2 or above.
