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 版本低于 10.4.2、10.2.6、10.0.9 和 9.4.14 的环境中，未授权用户可通过“事件类型生成器”（Event Type Builder）诱导已认证用户在其名下执行任意的搜索处理语言（SPL）查询，从而泄露所有相关数据和存储的凭据。该漏洞的发生是因为“事件类型生成器”在处理示例事件搜索时，接受了跨站请求输入并保留了影响 SPL 执行的值。攻击者需通过钓鱼手段诱骗目标用户在浏览器中发起请求，才能利用此漏洞；未授权用户无法随意单独利用该漏洞。更多详细信息请参阅 S

Vulnerability Title
SPL Injection through Cross-Site Request Forgery (CSRF) in the Event Type Builder in Splunk Web for 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, an unauthenticated user could cause an authenticated user to run arbitrary Search Processing Language (SPL) searches on their behalf through the Event Type Builder. This could expose all relevant data and stored credentials. The vulnerability is possible when the Event Type Builder accepts cross-site request input and retains SPL-affecting values while building sample event searches. The vulnerability requires the attacker to phish the affected user by tricking them into initiating a request within their browser. The unauthenticated user should not be able to exploit the vulnerability at will. For more information see Automatically find and build event types (https://help.splunk.com/en/splunk-enterprise/manage-knowledge-objects/knowledge-management-manual/9.0/event-types/automatically-find-and-build-event-types) in the Splunk documentation.
