In Splunk Enterprise versions below 10.2.0, 10.0.2, 9.4.7, 9.3.9, and 9.2.11, a user of a Splunk Search Head Cluster (SHC) deployment who holds a role with access to the Splunk _internal index could view the RSA accessKey value from the <u>Authentication.conf</u> file, in plain text.
AnalysisAI
Splunk Enterprise versions before 10.2.0, 10.0.2, 9.4.7, 9.3.9, and 9.2.11 expose RSA access keys in plain text within the Authentication.conf file to users with access to the _internal index on Search Head Cluster deployments. A privileged user with appropriate role permissions could read these sensitive credentials, compromising authentication security. No patch is currently available for this medium-severity vulnerability.
