CVE-2019-4109
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 · uneditedIBM WebSphere eXtreme Scale 8.6 Admin Console could allow a remote attacker to hijack the clicking action of the victim. By persuading a victim to visit a malicious Web site, a remote attacker could exploit this vulnerability to hijack the victim's click actions and possibly launch further attacks against the victim. IBM X-Force ID: 158102.
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 confidenceIBM WebSphere eXtreme Scale 8.6 Admin Console is vulnerable to clickjacking, allowing a remote attacker to embed the admin console in an iframe on a malicious website and hijack the victim's click actions to perform unauthorized operations on the legitimate application.

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 installed IBM WebSphere eXtreme Scale versionLocate and inspect the version information for the IBM WebSphere eXtreme Scale installation, typically found in product documentation, installation logs, or via the admin console startup outputAffected if The installed version is 8.6.0 through 8.6.1.2 (inclusive)
-
Confirm admin console is accessibleVerify that the IBM WebSphere eXtreme Scale admin console is running and reachable over the networkAffected if The admin console is exposed and accessible to users or attackers
-
Check for X-Frame-Options header on admin consoleSend an HTTP request to the admin console URL and inspect the response headers for the presence of X-Frame-Options header with value DENY or SAMEORIGINAffected if The X-Frame-Options header is absent or set to a permissive value such as ALLOW-FROM (not supported in modern browsers)
-
Check for CSP frame-ancestors directive on admin consoleInspect the Content-Security-Policy response header from the admin console for the frame-ancestors directiveAffected if The Content-Security-Policy header is absent or does not include frame-ancestors directive restricting iframe embedding
User is affected if IBM WebSphere eXtreme Scale version is between 8.6.0 and 8.6.1.2 inclusive, the admin console is accessible, and neither X-Frame-Options nor CSP frame-ancestors headers are properly configured to prevent iframe embedding.

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 data8.6.1.3
Implement X-Frame-Options: DENY or SAMEORIGIN header, or configure Content Security Policy (CSP) frame-ancestors directive to prevent the admin console from being embedded in iframes.
