In Splunk Enterprise versions lower than 8.2.12, 9.0.6, and 9.1.1, an attacker can use the `printf` SPL function to perform a denial of service (DoS) against the Splunk Enterprise instance.

In Splunk Enterprise versions lower than 9.0.6 and 8.2.12, a malicious actor can send a malformed security assertion markup language (SAML) request to the `/saml/acs` REST endpoint which can cause a denial of service through a crash or hang of the Splunk daemon.

In Splunk Enterprise versions below 9.1.1, 9.0.6, and 8.2.12, an attacker can craft a special web request that can result in reflected cross-site scripting (XSS) on the “/app/search/table” web endpoint. Exploitation of this vulnerability can lead to the execution of arbitrary commands on the Splunk platform instance.

On Splunk Enterprise versions below 9.0.5, 8.2.11, and 8.1.14, and in Splunk Cloud Platform versions below 9.0.2303.100, an unauthorized user can access the {{/services/indexing/preview}} REST endpoint to overwrite search results if they know the search ID (SID) of an existing search job.

In Splunk Enterprise versions below 9.0.5, 8.2.11, and 8.1.14, and Splunk Cloud Platform versions below 9.0.2303.100, an attacker can exploit a vulnerability in the {{dump}} SPL command to cause a denial of service by crashing the Splunk daemon.

In Splunk Enterprise versions below 9.0.5, 8.2.11, and 8.1.14, and in Splunk Cloud Platform versions below 9.0.2303.100, a low-privileged user can perform an unauthorized transfer of data from a search using the ‘copyresults’ command if they know the search ID (SID) of a search job that has recently run.

In Splunk Enterprise versions below 9.0.5, 8.2.11. and 8.1.14, and Splunk Cloud Platform versions below 9.0.2303.100, a low-privileged user who holds the ‘user’ role can see the hashed version of the initial user name and password for the Splunk instance by using the ‘rest’ SPL command against the ‘conf-user-seed’ REST endpoint.

In Splunk Enterprise versions below 9.0.5, 8.2.11, and 8.1.14, and Splunk Cloud Platform versions below 9.0.2303.100, a low-privileged user can trigger an HTTP response splitting vulnerability with the ‘rest’ SPL command that lets them potentially access other REST endpoints in the system arbitrarily.

In versions of Splunk Enterprise below 9.0.5, 8.2.11, and 8.1.14, and Splunk Cloud Platform below version 9.0.2303.100, a low-privileged user who holds a role that has the ‘edit_user’ capability assigned to it can escalate their privileges to that of the admin user by providing specially crafted web requests.

On Splunk Enterprise versions below 9.0.5, 8.2.11, and 8.1.14, an unauthenticated attacker can send specially-crafted messages to the XML parser within SAML authentication to cause a denial of service in the Splunk daemon.
