Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Rancher Server 1.2.0+ contains a vulnerability where authenticated users can disable access control through an API call, allowing privilege escalation and unauthorized access to cluster resources.

MitigationUpgrade Rancher Server to version v1.2.4, v1.3.5, v1.4.3, v1.5.3 or later. Verify access control remains enabled after upgrade.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify Rancher Server version
    Check the Rancher UI footer or use the API endpoint /v1/settings/server-version to retrieve the exact version string
    Affected if The version falls within >= 1.2.0 < 1.2.4, >= 1.3.0 < 1.3.5, >= 1.4.0 < 1.4.3, or >= 1.5.0 < 1.5.3
  2. Verify access control status
    Navigate to the Rancher UI under Admin > Access Control or query the API endpoint /v1/settings/authentication to confirm whether access control is enabled
    Affected if Access control is disabled when it should be enabled, indicating possible exploitation
  3. Audit recent access control configuration changes
    Review Rancher audit logs or the API /v1/settings/authentication for any recent modifications to the authentication settings, including who made the change and when
    Affected if Changes to authentication settings exist that were not initiated by an administrator
  4. Check for unauthorized API access
    Inspect Rancher API access logs or audit trail for API calls to endpoints that modify access control settings, such as settings/authentication, from unexpected users or IPs
    Affected if API calls modifying access control were made by users who should not have that permission

A user is affected if their Rancher Server version is within any of the vulnerable ranges and access control has been disabled or modified without authorization.
