CVE-2015-7786
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 · uneditedCross-site scripting (XSS) vulnerability in the NTT DATA Smart Sourcing JavaScript module 2003-11-26 through 2013-07-09 for Web Analytics Service allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.
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 · moderate confidenceCross-site scripting (XSS) vulnerability in the NTT DATA Smart Sourcing JavaScript module for Web Analytics Service. The vulnerability allows remote attackers to inject arbitrary web script or HTML via unspecified vectors. This is a classic input validation failure in the JavaScript module used for tracking/analytics, likely stemming from unvalidated or improperly sanitized user-supplied data being reflected in web pages without proper encoding.

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 if NTT DATA Web Analytics JavaScript is presentSearch your web application source code, HTML templates, and page includes for references to 'nttdata', 'smart sourcing', or the analytics JavaScript file (commonly named like 'ntt_analytics.js' or similar tracking script)Affected if The NTT DATA Smart Sourcing JavaScript module for web analytics is included in any web page
-
Locate the analytics JavaScript module fileFind the actual JavaScript file in your web application's static resources, scripts, or third-party includes directory. Check for files containing 'nttdata' or 'analytics' in the filename or contentAffected if A JavaScript file from the NTT DATA Web Analytics Service exists in your environment
-
Check for version information in the moduleOpen the analytics JavaScript file and search for version strings, such as 'version', 'v=', or build numbers in the file header or commentsAffected if The module displays any version number (all versions are affected per vendor advisory)
-
Verify the analytics tracking is actively runningLoad a page that includes the analytics script and inspect the browser developer console or network tab for requests to NTT DATA analytics endpointsAffected if The vulnerable JavaScript module is executing in user browsers
Your environment is affected if the NTT DATA Smart Sourcing JavaScript module for Web Analytics Service is present and active in your web pages, regardless of version since all versions are vulnerable.

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 robust input validation and output encoding for all user-supplied data rendered by the JavaScript module. Since the affected product is older (2003-2013), consider upgrading to a supported version if available, or implement context-aware output escaping in the analytics JavaScript code.
