Quick assessment

Affected
Elastic Kibana
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Elastic Kibana是荷兰Elastic公司开源的一个视觉化仪表板。 Elastic kibana 7.11.0至7.17.29版本、8.0.0至8.19.15版本、9.0.0至9.3.4版本和9.4.0至9.4.1版本存在路径遍历漏洞，该漏洞源于路径遍历问题，可能导致低权限用户利用标签创建权限使管理操作作用于非预期目标，从而未授权删除特权资源（包括管理账户和其他组织资产）。此漏洞利用需要管理员与受影响界面交互。

Vulnerability Title
Improper Limitation of a Pathname to a Restricted Directory in Kibana Leading to Unauthorized Deletion of Privileged Resources
Source: CVE Program / CVE List V5
Vulnerability Description
Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') (CWE-22) in Kibana can lead to the unauthorized deletion of privileged resources via Path Traversal (CAPEC-126). A low-privileged user holding tag creation privileges could cause a subsequent administrative action in the tag management interface to act on an unintended target, resulting in the deletion of privileged resources including administrative accounts and other organizational assets. Exploitation requires an administrator to interact with the affected interface.
