CVE-2018-2015
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 API Connect 2018.1 and 2018.4.1.4 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: 155195.
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 confidenceThis is a clickjacking vulnerability in IBM API Connect 2018.1 and 2018.4.1.4. An attacker can embed the IBM API Connect interface in an invisible iframe on a malicious website, overlaying hidden or disguised clickable elements over legitimate UI buttons. This tricks authenticated users into performing unintended actions by hijacking their mouse clicks.

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 API Connect versionAccess the API Connect admin or developer portal UI and locate the version information, typically found in the footer, About section, or system information page. Alternatively, check installation directories or configuration files for version metadata.Affected if The installed version is >= 2018.1.0 and <= 2018.4.1.4
-
Inspect X-Frame-Options HTTP response headerUse a browser developer tool or command-line tool (curl -I) to make a request to the API Connect portal/admin URL and examine the response headers for the presence of X-Frame-Options with value DENY or SAMEORIGIN.Affected if The X-Frame-Options header is absent, or present but set to ALLOW-FROM an untrusted domain, or missing entirely from responses.
-
Inspect Content-Security-Policy header for frame-ancestorsExamine HTTP response headers from the API Connect UI for a Content-Security-Policy header that includes the frame-ancestors directive restricting iframe embedding.Affected if Content-Security-Policy header is absent, or does not include frame-ancestors directive, or frame-ancestors allows arbitrary domains.
-
Verify iframe embeddabilityCreate a test HTML page with an iframe pointing to the API Connect login or admin URL and attempt to load it in a browser to confirm the application can be embedded.Affected if The application loads successfully within the iframe without being blocked by browser security restrictions.
If the installed version falls between 2018.1.0 and 2018.4.1.4 AND the application can be embedded in an iframe due to missing or weak X-Frame-Options and CSP frame-ancestors protections, the environment is affected by this clickjacking vulnerability.

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 dataImplement X-Frame-Options: DENY or SAMEORIGIN header, and/or configure Content-Security-Policy frame-ancestors directive to prevent the application from being embedded in iframes on untrusted domains.
