CVE-2019-19758
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 interface of Lenovo EZ Media & Backup Center, ix2 & ix2-dl version 4.1.406.34763 and prior could allow an unauthenticated, remote attacker to redirect a user to an untrusted web page.
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 confidenceThis is an open redirect vulnerability in the web interface of Lenovo EZ Media & Backup Center and ix2/ix2-dl storage devices. An unauthenticated remote attacker can craft malicious URLs containing redirect parameters that cause the application's web interface to forward users to arbitrary external websites, potentially leading to phishing attacks or credential theft.

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 device modelAccess the device's web interface or check the physical label to confirm the model is either Lenovo EZ Media & Backup Center, ix2, or ix2-dl storage device.Affected if The device is any of these three models.
-
Check the firmware versionLog into the device web interface and navigate to the System Settings or About page to view the installed firmware version. Compare this version against 4.1.406.34763.Affected if The firmware version is 4.1.406.34763 or lower.
-
Verify web interface is accessibleAttempt to access the device's web management interface over HTTP/HTTPS from a network location. Confirm the interface responds without authentication.Affected if The web interface is reachable without authentication on the network.
-
Test for open redirect vulnerabilityUsing a browser or curl, navigate to a URL on the device that includes a redirect parameter pointing to an external domain, such as: http://<device-ip>/cgi-bin/cgi?redirect=http://example.com. Observe if the application redirects to the external site.Affected if The application redirects to the arbitrary URL specified in the redirect parameter.
A user is affected if they have a Lenovo EZ Media & Backup Center, ix2, or ix2-dl device running firmware version 4.1.406.34763 or lower, with the web interface accessible over the network.

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 firmware update if available. If no update exists, consider restricting access to the web management interface via network segmentation or firewall rules to limit exposure to unauthenticated attackers.
