Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
In Splunk Enterprise versions below 8.1.12, 8.2.9, and 9.0.2, a remote user who can create search macros and schedule search reports can cause a denial of service through the use of specially crafted search macros.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

A remote authenticated user with permissions to create search macros and schedule search reports can exploit specially crafted search macros to cause denial of service in Splunk Enterprise versions before 8.1.12, 8.2.9, and 9.0.2.

MitigationUpgrade Splunk Enterprise to version 8.1.12, 8.2.9, 9.0.2 or later to remediate this vulnerability.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Check Splunk Enterprise version
    Navigate to Settings > System > Server information, or run: splunk version
    Affected if Version is 8.1.0-8.1.11, 8.2.0-8.2.8, or any 9.0.x version below 9.0.2205 (for Cloud)
  2. Verify user permissions for search macro creation
    Go to Settings > Users and authentication > Roles, or query the Splunk internal index: | rest /services/authorization/roles | table role, capabilities | search capabilities=*search_macro*
    Affected if Any role grants the 'run_search_macro' or 'edit_search_macro' capability to non-admin users
  3. Identify users with scheduled report permissions
    Review roles for 'schedule_search' capability: | rest /services/authorization/roles | table role, capabilities | search capabilities=*schedule*
    Affected if Non-admin roles have the ability to schedule search reports
  4. Review existing search macros for suspicious content
    Go to Settings > Advanced search > Search macros, or query: | rest /services/saved/searches | search action.search_type=macro | table title search
    Affected if Any search macros contain recursive or nested macro calls that could cause resource exhaustion
  5. Check for scheduled searches that reference macros
    Query saved searches: | rest /services/saved/searches | search action.trigger.hook!="" OR cron_schedule!="" | table title cron_schedule search
    Affected if Scheduled searches reference custom macros that could be exploited

Your Splunk is affected if it runs a version below 8.1.12/8.2.9/9.0.2205 AND any authenticated user has both macro creation and scheduled report permissions.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

Interim mitigation

Upgrade Splunk Enterprise to version 8.1.12, 8.2.9, 9.0.2 or later to remediate this vulnerability.

Recommended fix High confidence

Splunk Enterprise: 8.1.12, 8.2.9, or 9.0.2 (depending on your current major version); Splunk Cloud Platform: 9.0.2205

  1. Identify the currently running Splunk Enterprise version using the About page in Splunk Web or by running 'splunk --version' from the CLI
  2. For Splunk Enterprise 8.1.x deployments: Upgrade to version 8.1.12 or later
  3. For Splunk Enterprise 8.2.x deployments: Upgrade to version 8.2.9 or later
  4. For Splunk Enterprise 9.0.x deployments: Upgrade to version 9.0.2 or later
  5. For Splunk Cloud Platform: Contact Splunk Support to schedule an upgrade to version 9.0.2205 or later
  6. After upgrading, verify the Splunk services are running correctly
  7. Test that scheduled searches and search macros function normally
