CVE-2019-16024
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 · uneditedA vulnerability in the web-based management interface of Cisco Crosswork Change Automation could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based management interface of an affected system. The vulnerability is due to insufficient validation of user-supplied input by the web-based management interface of an affected system. An attacker could exploit this vulnerability by persuading a user to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information.
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 Cisco Crosswork Change Automation web-based management interface. An unauthenticated, remote attacker can inject malicious script through insufficiently validated user-supplied input, executing arbitrary code in the context of the affected interface when a user clicks a crafted link.

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 Cisco Crosswork product and versionAccess the web-based management interface and navigate to the About or System Information page to view the installed version. Alternatively, use the CLI command 'show version' or check the installed packages via the package manager.Affected if The product is Cisco Crosswork Change Automation version < 3.1, or Cisco Crosswork Network Automation version 3.0 or 3.1
-
Confirm the web-based management interface is activeVerify the Cisco Crosswork web interface is accessible by attempting to reach the management URL (typically https://<hostname>/ or the configured management IP). Check if the HTTP/HTTPS service for the web interface is running.Affected if The web-based management interface is enabled and reachable on the network
-
Review web logs for XSS indicatorsExamine the web server access logs and application logs for unusual query parameters, script tags, or encoded XSS payloads that may indicate exploitation attempts. Look for patterns like '<script>', 'javascript:', or other HTML/script injection attempts in request parameters.Affected if Logs contain suspicious requests with XSS patterns targeting the user-supplied input fields in the interface
A user is affected if they are running Cisco Crosswork Change Automation before version 3.1 or Cisco Crosswork Network Automation versions 3.0 or 3.1, and the web-based management interface is exposed.

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 data3.1
Implement proper input validation and output encoding for all user-supplied data in the web interface. Consider deploying Content Security Policy (CSP) headers as defense-in-depth. Users should be advised not to click untrusted links.
