CVE-2017-3101
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 · uneditedAdobe Connect versions 9.6.1 and earlier have a clickjacking vulnerability. Successful exploitation could lead to a clickjacking attack.
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 confidenceAdobe Connect versions 9.6.1 and earlier contain a clickjacking vulnerability where the application can be embedded in an iframe on malicious pages, allowing attackers to overlay invisible or disguised interface elements and trick users into performing unintended actions such as granting permissions or modifying settings.

Affected products & versions What the vendor confirmedThe version ranges the vendor confirmed as vulnerable. If your version sits inside a range here, treat yourself as exposed until you have upgraded.

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.
-
Check Adobe Connect versionAccess the Adobe Connect login page or admin interface, then locate the version information typically found in Help > About or in the admin dashboard. Alternatively, check the install directory for a version file or review the HTTP response headers if version info is exposed.Affected if The installed version is 9.6.1 or earlier.
-
Inspect X-Frame-Options headerUse browser developer tools or a command-line tool like curl to fetch the HTTP response headers from the Adobe Connect login page (for example: curl -I https://your-connect-server.example.com). Look for the X-Frame-Options header in the response.Affected if The X-Frame-Options header is missing, or is set to a permissive value such as ALLOW-FROM (not DENY or SAMEORIGIN).
-
Inspect Content-Security-Policy frame-ancestors directiveExamine the Content-Security-Policy HTTP header in the response from the Adobe Connect server. Check whether the frame-ancestors directive is present and whether it restricts embedding to trusted domains.Affected if The Content-Security-Policy header is missing or does not include the frame-ancestors directive, or frame-ancestors allows untrusted sources.
-
Verify iframe embedding is possibleCreate a simple HTML page with an iframe pointing to your Adobe Connect URL (for example: <iframe src="https://your-connect-server.example.com"></iframe>) and open it in a browser. Observe whether the Adobe Connect page loads inside the iframe.Affected if The Adobe Connect page successfully renders inside the iframe from an untrusted domain.
You are affected if your Adobe Connect version is 9.6.1 or earlier AND the application can be embedded in an iframe 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 dataDeploy X-Frame-Options: DENY or SAMEORIGIN headers, and/or implement Content-Security-Policy with frame-ancestors directive to prevent the application from being embedded in iframes on untrusted domains.
