CVE-2017-8017
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 · uneditedEMC Network Configuration Manager (NCM) 9.3.x, 9.4.0.x, 9.4.1.x, and 9.4.2.x is affected by a reflected cross-site scripting Vulnerability that could potentially be exploited by malicious users to compromise the affected system.
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 confidenceEMC Network Configuration Manager versions 9.3.x through 9.4.2.x contains a reflected cross-site scripting (XSS) vulnerability. The flaw allows attackers to inject malicious JavaScript or HTML into web requests that are reflected back to users without proper sanitization, potentially enabling session hijacking, credential theft, or manipulation of web content.

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 EMC NCM versionAccess the EMC Network Configuration Manager administrative interface or check the product About/Version information page within the application. If you have CLI access to the server, use the vendor's standard method to query the installed software version.Affected if The displayed version matches 9.3.x, 9.4.x, 9.4.1.x, or 9.4.2.x (including 9.3, 9.4, 9.4.1, 9.4.2)
-
Confirm the web interface is enabledVerify that the EMC NCM web-based management console is accessible via HTTP/HTTPS from a browser or by checking the service/configuration that exposes the web application.Affected if The web interface responds to requests, indicating it is enabled and operational
-
Review web request handling for unsanitized input reflectionSince this is a reflected XSS vulnerability, manually test by submitting suspicious characters or scripts in web form parameters and observing whether the input is returned unescaped in the response. Alternatively, review application logs or HTTP traffic for evidence of reflected parameters.Affected if Web parameters are reflected back in responses without proper encoding or sanitization
The environment is affected if EMC Smarts Network Configuration Manager version 9.3, 9.4, 9.4.1, or 9.4.2 is installed and the web interface is exposed and reflects user input without sanitization.

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 dataApply the vendor-supplied patch or upgrade to a non-vulnerable version of EMC NCM. As an interim measure, implement input validation and output encoding on the web interface, and consider deploying a WAF rule to filter malicious XSS payloads.
