Description

The following analytic identifies attempts to exploit a reflective Cross-Site Scripting (XSS) vulnerability in the Splunk Distributed Monitoring Console app. It detects GET requests with suspicious query parameters by analyzing splunkd_web logs in the _internal index. This activity is significant because it targets a known vulnerability (CVE-2022-27183) that could allow attackers to execute arbitrary scripts in the context of the user's browser. If confirmed malicious, this could lead to unauthorized actions, data theft, or further compromise of the Splunk environment.
