CVE-2018-12412
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 realm server (tibrealmserver) component of TIBCO Software Inc. TIBCO FTL - Community Edition, TIBCO FTL - Developer Edition, and TIBCO FTL - Enterprise Edition contains a vulnerability which may allow an attacker to perform cross-site request forgery (CSRF) attacks. Affected releases are TIBCO Software Inc. TIBCO FTL - Community Edition: versions up to and including 5.4.0, TIBCO FTL - Developer Edition: versions up to and including 5.4.0, TIBCO FTL - Enterprise Edition: versions up to and including 5.4.0.
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 confidenceA cross-site request forgery (CSRF) vulnerability exists in the tibrealmserver component of TIBCO FTL. This flaw allows attackers to trick authenticated users into unknowingly executing unintended actions on the realm server, potentially compromising the FTL deployment's security by forcing authenticated requests to perform unauthorized operations.

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 TIBCO FTL installation and versionLocate the TIBCO FTL installation directory and check the version file or use the installed version reporting mechanismAffected if Installed version is 1.0.0 through 5.3.x (any version >= 1.0.0 and < 5.4.0)
-
Confirm tibrealmserver component is in useIdentify whether the tibrealmserver (realm server) component is running or configured in the FTL deploymentAffected if The realm server component is active and accepting HTTP/HTTPS requests from clients
-
Check if realm server validates Origin or Referer headersInspect the realm server configuration files or examine incoming request handling to determine if Origin/Referer header validation is implementedAffected if No Origin or Referer header validation is performed on incoming requests to the realm server
-
Verify anti-CSRF token or SameSite cookie configurationReview the realm server endpoint configurations and cookie settings to determine if anti-CSRF tokens or SameSite attributes are defined for state-changing operationsAffected if Anti-CSRF tokens and SameSite cookie attributes are not configured on realm server endpoints
The environment is affected if TIBCO FTL version is >= 1.0.0 and < 5.4.0 AND the tibrealmserver is active AND CSRF protections (Origin/Referer validation, anti-CSRF tokens, or SameSite cookies) are not implemented on the realm server.

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 data5.4.0
Implement anti-CSRF tokens or SameSite cookie attributes on all realm server endpoints, verify Origin/Referer headers on incoming requests, and apply any vendor-provided patches for versions beyond 5.4.0.
