The SPL above uses the following Macros:

:information_source: splunk_reflected_xss_in_the_templates_lists_radio_filter is a empty macro by default. It allows the user to filter out any results (false positives) without editing the SPL.

How To Implement

This vulnerability only affects instances with Splunk Web enabled. This detection does not require you to ingest any new data. The detection does require the ability to search the _internal index.

Known False Positives

This search may produce false positives as it is difficult to pinpoint all possible XSS injection characters in a single search string. Special attention is required to "en-US/list/entities/x/ui/views" which is the vulnerable injection point.
