Splunk Splunk Enterprise
Exploitation

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 10.4.4、10.2.8、10.0.11 和 9.4.16 之前的版本中，未持有"admin"或"power"角色的 Splunk 用户，可以在其无权访问的应用中创建、移动、编辑或删除其拥有的 sourcetype（源类型）重命名配置。 该漏洞之所以存在，是因为当 Splunk Web 功能开启时，Splunk Web 在执行 sourcetype 重命名操作前，并未验证所需的应用权限。 更多信息请参阅 Splunk 官方文档中的“在搜索时重命名源类型”章节：https:/

Vulnerability Title
Missing Authorization through Sourcetype Renaming in Splunk Web for Splunk Enterprise
Source: CVE Program / CVE List V5
Vulnerability Description
In Splunk Enterprise versions below 10.4.4, 10.2.8, 10.0.11, and 9.4.16, a user who does not hold the "admin" or "power" Splunk roles could create, move, edit, or delete sourcetype renaming configurations that they own in apps that they do not have permission to access.
The vulnerability is possible when Splunk Web is turned on because Splunk Web does not verify the required app permissions before it performs sourcetype renaming operations.
