CVE-2018-7432
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 · uneditedSplunk Enterprise 6.2.x before 6.2.14, 6.3.x before 6.3.10, 6.4.x before 6.4.7, and 6.5.x before 6.5.3; and Splunk Light before 6.6.0 allow remote attackers to cause a denial of service via a crafted HTTP request.
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 · high confidenceSplunk Enterprise and Splunk Light contain a denial of service vulnerability that can be triggered by remote attackers sending crafted HTTP requests. The vulnerability affects multiple version branches (6.2.x, 6.3.x, 6.4.x, 6.5.x for Enterprise; all versions before 6.6.0 for Light), and successful exploitation causes the Splunk service to become unavailable.

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 checksWork through these to decide whether this CVE applies to you.
-
Check if Splunk is installedRun the command: splunk version or look for the Splunk installation directory (typically /opt/splunk or C:\Program Files\Splunk)Affected if Splunk is not installed on the system
-
Determine the installed Splunk versionExecute: splunk version from the Splunk bin directory, or log into the Splunk web interface and navigate to Settings > About > VersionAffected if Unable to retrieve version information
-
Compare your version against affected rangesCheck if your installed version falls within: Enterprise 6.2.x before 6.2.14, 6.3.x before 6.3.10, 6.4.x before 6.4.7, 6.5.x before 6.5.3; or Splunk Light any version before 6.6.0Affected if Installed version is within any of these ranges: >= 6.2.0 and < 6.2.14, or >= 6.3.0 and < 6.3.10, or >= 6.4.0 and < 6.4.7, or >= 6.5.0 and < 6.5.3, or < 6.6.0 for Splunk Light
-
Confirm Splunk HTTP management interface is accessibleAttempt to access the Splunk web interface on port 8000 or management port 8089Affected if The HTTP interface is exposed and reachable, making the DoS vector possible
You are affected if your Splunk Enterprise version is 6.2.x before 6.2.14, 6.3.x before 6.3.10, 6.4.x before 6.4.7, or 6.5.x before 6.5.3, or if your Splunk Light version is any version below 6.6.0, and the HTTP interface is accessible.
