In Splunk Enterprise versions below 10.2.1, 10.0.4, 9.4.9, and 9.3.10, and Splunk Cloud Platform versions below 10.2.2510.7, 10.1.2507.17, 10.0.2503.12, and 9.3.2411.124, a low-privileged user that does not hold the "admin" or "power" Splunk roles could retrieve sensitive information by inspecting the job's search log due to improper access control in the MongoClient logging channel.
AnalysisAI
Improper access control in Splunk Enterprise and Cloud Platform versions below specified thresholds allows low-privileged users without admin or power roles to extract sensitive information from job search logs through the MongoClient logging channel. Affected versions include Enterprise 10.2.1, 10.0.4, 9.4.9, and 9.3.10, as well as corresponding Cloud Platform releases. No patch is currently available for this medium-severity vulnerability.
