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 · unedited
A vulnerability in the web-based management interface of Cisco HyperFlex HX Data Platform could allow an unauthenticated, remote attacker to redirect a user to a malicious web page. This vulnerability is due to improper input validation of the parameters in an HTTP request. An attacker could exploit this vulnerability by persuading a user to click a crafted link. A successful exploit could allow the attacker to redirect a user to a malicious website.

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 confidence

This is an Open Redirect (CWE-601) vulnerability in Cisco HyperFlex HX Data Platform's web-based management interface. The vulnerability stems from improper input validation of URL parameters in HTTP requests, allowing an unauthenticated attacker to craft malicious links that redirect users to arbitrary websites. Successful exploitation requires social engineering to trick users into clicking crafted links.

MitigationApply Cisco's official patch for CVE-2023-20263 when available. As an interim control, implement URL allowlisting or disable open redirects in the web interface, and educate users about the risks of clicking untrusted links.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify HyperFlex HX Data Platform version
    Access the cluster's management interface or run 'show version' via SSH to the HX cluster controller. Alternatively, check the installed packages via the HX Connect UI or API endpoint.
    Affected if The installed version is exactly 5.0 or exactly 5.5
  2. Confirm web-based management interface is enabled
    Check if the web UI is accessible by navigating to the HyperFlex management URL (typically on port 443). Verify the service is running via 'show running-config' or by querying the management service status.
    Affected if The web-based management interface is exposed and accessible
  3. Review HTTP access logs for redirect patterns
    Examine web server access logs (usually in /var/log/ or via the management UI) for incoming requests containing 'redirect=', 'url=', or 'next=' parameters with external domains. Search for patterns like 'http://' or 'https://' in query strings.
    Affected if Logs show unauthenticated requests with suspicious URL redirection parameters pointing to external domains

A defender is affected if they are running Cisco HyperFlex HX Data Platform version 5.0 or 5.5 with the web management interface exposed, and external URL redirection parameters appear in their access logs.
