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 10.4.2、10.2.6、10.0.9 和 9.4.14 版本以下，不具备 “admin” 或 “power” Splunk 角色的用户，可通过上传恶意知识包并使其在分布式搜索中被调用，从而执行远程代码执行（RCE）。此举可导致访问所有相关数据，并影响系统的完整性与可用性。 该漏洞产生的原因是：用于上传知识包的表示状态转移（REST）API 端点不需要具备高权限的 “edit_dist_peer” 能力；同时，分布式搜索功能会接受来自不具备该能力的用户所提供的、由调用方指定

Vulnerability Title
Remote Code Execution (RCE) through the REST API in Splunk Enterprise
Source: CVE Program / CVE List V5
Vulnerability Description
In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, a user who does not hold the "admin" or "power" Splunk roles could perform Remote Code Execution (RCE) by uploading a malicious knowledge bundle and causing it to be used by distributed search, which can allow for access to all relevant data and affect system integrity and availability. The vulnerability is possible because the Representational State Transfer (REST) API endpoint for knowledge bundle upload does not require the high-privilege capability edit_dist_peer, and distributed search accepts caller-supplied knowledge bundle selections from users who do not hold that capability. For more information see What search heads send to search peers (https://help.splunk.com/en/splunk-enterprise/administer/distributed-search/9.2/knowledge-bundle-replication/what-search-heads-send-to-search-peers), About configuring role-based user access (https://help.splunk.com/en/splunk-enterprise/administer/manage-users-and-security/9.0/manage-splunk-platform-users-and-roles/about-configuring-role-based-user-access), Define roles on the Splunk platform with capabilities (https://help.splunk.com/en/splunk-enterprise/administer/manage-users-and-security/9.1/manage-splunk-platform-users-and-roles/define-roles-on-the-splunk-platform-with-capabilities), and Using the REST API reference (https://help.splunk.com/en/splunk-enterprise/rest-api-reference/10.4/introduction/using-the-rest-api-reference) in the Splunk documentation.
