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 8.0.0版本至8.19.16版本、9.0.0版本至9.3.5版本和9.4.0版本至9.4.2版本存在路径遍历漏洞，该漏洞源于Kibana Fleet在Fleet Server主机配置中未拒绝相对路径遍历序列，允许用户提供的标识符被存储并用于后续请求，可能导致未经授权删除Kibana资源。

Vulnerability Title
Relative Path Traversal in Kibana Fleet Leading to Unauthorized Deletion of Users and Other Resources
Source: CVE Program / CVE List V5
Vulnerability Description
Relative Path Traversal (CWE-23) in Kibana can lead to the unauthorized deletion of Kibana resources via Relative Path Traversal (CAPEC-139). Kibana Fleet accepted a user-supplied identifier for a Fleet Server host configuration without rejecting relative traversal sequences. The identifier is stored as provided and is later incorporated into the request that Kibana issues when that configuration is removed.
