## Description

In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, a user that holds a role with the schedule\_search capability could store a malicious script in an alert trigger condition field. When another user opens the crafted link, the script runs in the browser of that user and could access all data available to that user. The vulnerability is possible because Splunk Web uses the alert threshold value in generated alert trigger condition markup without escaping special characters. Successful exploitation requires another user to open the crafted link. For more information see Configure alert trigger conditions (https://help.splunk.com/en/splunk-enterprise/alert-and-respond/alerting-manual/10.4/manage-alert-trigger-conditions-and-throttling/configure-alert-trigger-conditions) and Define roles on the Splunk platform with capabilities (https://help.splunk.com/en/splunk-enterprise/administer/manage-users-and-security/10.2/manage-splunk-platform-users-and-roles/define-roles-on-the-splunk-platform-with-capabilities) in the Splunk documentation.
