CVE-2012-4936
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 web interface in Pattern Insight 2.3 allows remote attackers to conduct clickjacking attacks via a FRAME element.
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 confidenceThe web interface in Pattern Insight 2.3 is vulnerable to clickjacking attacks. Attackers can embed the application in a FRAME element and overlay it with deceptive content, tricking users into performing unintended actions such as clicking buttons or submitting data they did not intend to.

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 Pattern Insight versionAccess the Pattern Insight web interface and locate the version information, typically found in the About page, footer, or admin settings panelAffected if The installed version is exactly 2.3
-
Check if the web interface responds with X-Frame-Options headerSend an HTTP request to the Pattern Insight login page or main web interface and inspect the response headers for the presence of X-Frame-OptionsAffected if The X-Frame-Options header is missing from the HTTP response, or the header value is not set to DENY or SAMEORIGIN
-
Check if CSP frame-ancestors directive is configuredInspect the HTTP response headers for Content-Security-Policy header and verify if the frame-ancestors directive is present and properly configuredAffected if The CSP frame-ancestors directive is missing or not configured to prevent framing
-
Test frame embedding capabilityCreate a test HTML page with an IFRAME element pointing to the Pattern Insight application URL and open it in a browser to see if the application loads within the frameAffected if The Pattern Insight application successfully loads within a frame or iframe element, indicating it can be embedded by external sites
A user is affected if the installed Pattern Insight version is 2.3 AND the X-Frame-Options header is absent or set to a permissive value AND CSP frame-ancestors is not configured, allowing the application to be embedded in frames by attackers.

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 the X-Frame-Options header (DENY or SAMEORIGIN) or Content Security Policy (CSP) frame-ancestors directive on the web server to prevent the application from being embedded in FRAME/IFRAME elements.
