CVE-2023-42011
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 Sterling B2B Integrator Standard Edition 6.1 and 6.2 does not restrict or incorrectly restricts frame objects or UI layers that belong to another application or domain, which can lead to user confusion about which interface the user is interacting with. IBM X-Force ID: 265508.
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 (UI Redressing) vulnerability where IBM Sterling B2B Integrator fails to restrict embedding within frame objects (iframes). An attacker could embed the application in an invisible frame and overlay malicious UI elements, tricking users into performing unintended actions. This stems from missing or misconfigured X-Frame-Options or Content-Security-Policy frame-ancestors headers.

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 IBM Sterling B2B Integrator versionLocate the installed version of IBM Sterling B2B Integrator in your environment. Check the product documentation, installation directory, or admin console for the version number.Affected if The installed version is 6.1 or 6.2 exactly.
-
Check for X-Frame-Options headerSend an HTTP request to the Sterling B2B Integrator web interface and inspect the response headers for the presence of X-Frame-Options. Use a browser developer tool, curl -I, or a network inspector to view headers.Affected if The X-Frame-Options header is missing, or is set to a permissive value such as ALLOW-FROM (which is deprecated and not widely supported), or is not set to DENY or SAMEORIGIN.
-
Check for Content-Security-Policy frame-ancestorsInspect the HTTP response headers from the Sterling B2B Integrator application for a Content-Security-Policy header that includes the frame-ancestors directive.Affected if The Content-Security-Policy header is missing entirely, or does not include a frame-restricting directive.
-
Verify iframe embeddabilityCreate a test HTML page with an iframe pointing to your Sterling B2B Integrator URL and attempt to load it in a browser, or use a command-line tool to fetch the response and verify it does not include clickjacking protections.Affected if The application loads successfully within the iframe, indicating no frame-breaking protections are active.
You are affected if your installed version is 6.1 or 6.2 AND the application can be embedded in iframes due to missing or weak X-Frame-Options and Content-Security-Policy frame-ancestors headers.

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 dataConfigure the web server or application to send X-Frame-Options: DENY (or SAMEORIGIN) and/or implement Content-Security-Policy with frame-ancestors directive to prevent the application from being embedded in unauthorized frames.
