CVE-2018-1432
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 InfoSphere Information Server 9.1, 11.3, 11.5, and 11.7 is vulnerable to cross-frame scripting which is a vulnerability that allows an attacker to load Information Server components inside an HTML iframe tag on a malicious page. The attacker could use this weakness to devise a Clickjacking attack to conduct phishing, frame sniffing, social engineering or Cross-Site Request Forgery attacks. IBM X-Force ID: 139360.
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 confidenceIBM InfoSphere Information Server versions 9.1, 11.3, 11.5, and 11.7 are vulnerable to cross-frame scripting (clickjacking). The application lacks proper X-Frame-Options or Content Security Policy frame-ancestors protections, allowing attackers to embed the application in an iframe on a malicious page. This enables clickjacking attacks where users can be tricked into performing unintended actions through overlaid invisible UI elements.

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 IBM InfoSphere Information Server versionLocate the version information in the IBM InfoSphere admin console, installation directory, or by querying the system. Common paths include the installation logs or version.info file in the installation directory.Affected if Version matches 9.1, 11.3, 11.5, or 11.7 exactly
-
Inspect HTTP response headers for X-Frame-OptionsUse browser developer tools (Network tab), curl -I command, or a header inspection tool to capture the HTTP response headers when accessing the IBM InfoSphere URL. Look for the X-Frame-Options header.Affected if The X-Frame-Options header is absent or set to a value other than DENY or SAMEORIGIN (such as ALLOW-FROM untrusted-origin)
-
Inspect HTTP response headers for Content-Security-Policy frame-ancestorsExamine the Content-Security-Policy header in the HTTP response. Verify whether the frame-ancestors directive is present and whether it restricts framing to trusted origins.Affected if The Content-Security-Policy header is absent, or the frame-ancestors directive is missing, not configured, or allows untrusted origins
A user is affected if their installed version is exactly 9.1, 11.3, 11.5, or 11.7 AND the application can be embedded in an iframe due to missing or misconfigured X-Frame-Options and Content-Security-Policy frame-ancestors protections.

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, or configure Content-Security-Policy with frame-ancestors directive to restrict framing to trusted origins only.
