Short explanation
A missing authorization vulnerability exists in Splunk Enterprise versions where users without admin or power roles can create, move, edit, or delete sourcetype renaming configurations in apps they lack access to when Splunk Web is enabled.
This vulnerability allows low-privileged users to manipulate sourcetype configurations in unauthorized applications, potentially compromising data integrity controls.
What should be done?
- Follow the vendor security advisory
- Apply updates for affected versions
Chain of evidence and sources
Splunk Enterprise sürümlerinde 10.4.4, 10.2.8, 10.0.11 ve 9.4.16 öncesi sürümler etkilenmektedir.
Splunk Web açık olduğunda, gerekli uygulama izinleri doğrulanmadan kaynak tipi yeniden adlandırma işlemleri gerçekleştirilebilir.
Show the technical text from the sources
In Splunk Enterprise versions below 10.4.4, 10.2.8, 10.0.11, and 9.4.16, a user who does not hold the "admin" or "power" Splunk roles could create, move, edit, or delete sourcetype renaming configurations that they own in apps that they do not have permission to access. The vulnerability is possible when Splunk Web is turned on because Splunk Web does not verify the required app permissions before it performs sourcetype renaming operations. For more information see Rename source types at search time (https://help.splunk.com/en/splunk-enterprise/get-started/get-data-in/10.6/configure-source-types/rename-source-types-at-search-time) in the Splunk documentation.
