Splunk Enterprise and Cloud Platform versions below specified thresholds fail to properly restrict access to the passwords configuration API endpoint, allowing low-privileged users without admin or power roles to retrieve hashed or plaintext credential values from passwords.conf. This information disclosure vulnerability could enable attackers to obtain sensitive authentication credentials for further system compromise. No patch is currently available.
Earlier versions of this analysis (1)
In Splunk Enterprise versions below 10.2.0, 10.0.3, 9.4.9, and 9.3.10, and Splunk Cloud Platform versions below 10.2.2510.5, 10.1.2507.16, 10.0.2503.11, and 9.3.2411.123, a low-privileged user that does not hold the "admin" or "power" Splunk roles could access the /splunkd/__raw/servicesNS/-/-/configs/conf-passwords REST API endpoint, which exposes the hashed or plaintext password values that are stored in the passwords.conf configuration file due to improper access control. [CVSS 6.5 MEDIUM]
