Quick assessment
Affected
Splunk Splunk Enterprise
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.
在 Splunk Enterprise 低于 10.4.3、10.2.7、10.0.10 和 9.4.15 的版本中，不具备“admin”或“power”Splunk 角色的用户，可以通过一个以表示层状态转移（REST）方式实现的 Application Programming Interface（API），使用用户可控的任务标识符，访问几乎全部属于其他用户搜索任务的信息，包括搜索查询文本、任务元数据、结果及预览结果。该漏洞之所以存在，是因为该 REST API 在返回搜索任务信息前，未充分验证任务的所有权。

Vulnerability Title
Improper Access Control in Search Job Retrieval through the REST API in Splunk Enterprise
Source: CVE Program / CVE List V5
Vulnerability Description
In Splunk Enterprise versions below 10.4.3, 10.2.7, 10.0.10, and 9.4.15, a user who does not hold the "admin" or "power" Splunk roles could use a user-controlled job identifier to access substantially all search job information from jobs that belong to other users, including search query text, job metadata, results, and preview results, through an Application Programming Interface (API) implemented as a Representational State Transfer (REST) API. The vulnerability is possible because the REST API does not fully validate job ownership before returning search job information.
