Executive Summary

This vulnerability is a path traversal issue in Kibana's dashboard management functionality. An authenticated user with limited permissions can create a dashboard using a specially crafted identifier that includes path traversal sequences. When an administrator later tries to delete this dashboard through the Kibana interface, the deletion request is redirected to an unintended internal endpoint. This redirection can cause unauthorized deletion of user accounts or other resources. Exploitation requires an administrator to perform the delete action on the malicious dashboard.

Impact Analysis

The vulnerability can lead to unauthorized deletion of user accounts or other critical resources within the Kibana environment. Since the deletion request is redirected to an unintended internal endpoint, it may cause loss of important data or disruption of services. The impact depends on an administrator performing the delete action on the maliciously crafted dashboard.

Detection Guidance

This vulnerability can be detected by reviewing Kibana audit logs for suspicious dashboard deletion events or identifiers containing path traversal sequences.

Specifically, administrators should look for dashboard identifiers that include unusual path traversal patterns, which may indicate attempts to exploit the vulnerability.

While no specific commands are provided, monitoring and searching Kibana audit logs for such suspicious activity is recommended.

Compliance Impact

The vulnerability allows an authenticated user with limited permissions to create a malicious dashboard that, when deleted by an administrator, can lead to unauthorized deletion of user accounts or other resources.

Such unauthorized deletion of user accounts or resources could potentially impact compliance with standards and regulations like GDPR or HIPAA, which require protection of user data integrity and availability.

However, the provided information does not explicitly discuss the direct impact on compliance with these regulations.

Mitigation Strategies

Immediate mitigation steps include upgrading Kibana to versions 8.19.16 or 9.3.5 where the vulnerability is fixed.

If upgrading is not possible immediately, restrict dashboard creation permissions to trusted users only.

Additionally, limit the Analytics > Dashboard > All permission to reduce the risk of exploitation.
