CVE-2018-17192
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 · uneditedThe X-Frame-Options headers were applied inconsistently on some HTTP responses, resulting in duplicate or missing security headers. Some browsers would interpret these results incorrectly, allowing clickjacking attacks. Mitigation: The fix to consistently apply the security headers was applied on the Apache NiFi 1.8.0 release. Users running a prior 1.x release should upgrade to the appropriate release.
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 confidenceApache NiFi versions prior to 1.8.0 applied X-Frame-Options headers inconsistently across HTTP responses, resulting in duplicate headers on some endpoints and missing headers on others. This inconsistency caused browsers to incorrectly interpret the clickjacking protection, allowing attackers to embed NiFi pages in invisible frames and trick users into performing unintended actions.

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.
-
Identify the installed NiFi versionCheck the NiFi application version through the UI (upper right corner of the NiFi dashboard) or by inspecting the bootstrap.conf file in the NiFi installation directory for the version propertyAffected if The installed version falls within >= 1.0.0 and <= 1.6.0
-
Test the main NiFi UI endpoint for X-Frame-Options headersSend an HTTP GET request to the NiFi UI root URL (e.g., http://hostname:8080/nifi/) and inspect the response headers for X-Frame-OptionsAffected if The header is missing, or the header appears multiple times (duplicate) in the response
-
Test API endpoints for X-Frame-Options headersSend an HTTP GET request to the NiFi API endpoint (e.g., http://hostname:8080/nifi-api/system-config) and inspect the response headersAffected if The X-Frame-Options header is missing from the API response but present in UI responses, indicating inconsistent application across endpoints
-
Compare headers across multiple endpointsMake requests to different NiFi endpoints such as the UI, API, and any proxy or load balancer fronts, and compare the X-Frame-Options header presence and value in each responseAffected if Any endpoint returns different X-Frame-Options header configuration than others, showing inconsistent application of the header
You are affected if NiFi version is between 1.0.0 and 1.6.0 and HTTP responses show inconsistent presence or duplicate X-Frame-Options headers across different endpoints.

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.
From vendor dataUpgrade Apache NiFi to version 1.8.0 or later, which applies X-Frame-Options headers consistently across all HTTP responses, eliminating the clickjacking vulnerability.
