CVE-2017-12346
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 · uneditedMultiple vulnerabilities in Cisco Data Center Network Manager (DCNM) Software could allow a remote attacker to inject arbitrary values into DCNM configuration parameters, redirect a user to a malicious website, inject malicious content into a DCNM client interface, or conduct a cross-site scripting (XSS) attack against a user of the affected software. Cisco Bug IDs: CSCvf40477, CSCvf63150, CSCvf68218, CSCvf68235, CSCvf68247.

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.
-
Confirm Cisco DCNM installationIdentify if Cisco Data Center Network Manager is installed on the system. Check for DCNM installation directories, services, or running processes related to 'dcnm' or 'Data Center Network Manager'.Affected if DCNM is not installed on the system, the user is not affected by this CVE.
-
Verify DCNM versionDetermine the installed version of Cisco DCNM. Check the application's about page, installation directory for version files, or use the DCNM CLI/tool with commands like 'dcnm -v' or similar version inquiry commands if available.Affected if The installed version is exactly 10.2(1) - other versions may have different risk levels.
-
Check web interface exposureDetermine if the DCNM web interface is accessible. Identify if the DCNM web server (typically on ports 80, 443, or 8080) is running and exposed to network access.Affected if The DCNM web interface is accessible - these are web-based vulnerabilities requiring user interaction with the web interface.
-
Inspect web logs for injection attemptsReview DCNM web server logs for suspicious parameters, unexpected redirects, or XSS payloads in request URLs, form submissions, or query strings.Affected if Logs contain evidence of injection attempts, malicious redirects, or XSS payloads targeting DCNM web endpoints.
A user is affected only if Cisco DCNM version 10.2(1) is installed and its web interface is accessible; other versions or non-installed states indicate no impact from this specific CVE.

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 Cisco patches for DCNM (Cisco Bug IDs CSCvf40477, CSCvf63150, CSCvf68218, CSCvf68235, CSCvf68247) or implement input validation and output encoding controls; also deploy web application firewall rules to block injection/XSS attempts.
