CVE-2018-1246
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 · uneditedDell EMC Unity and UnityVSA contains reflected cross-site scripting vulnerability. A remote unauthenticated attacker could potentially exploit this vulnerability by tricking a victim application user to supply malicious HTML or Java Script code to Unisphere, which is then reflected back to the victim and executed by the web browser.
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 confidenceA reflected cross-site scripting (XSS) vulnerability exists in Dell EMC Unisphere (the management web interface for Unity and UnityVSA storage systems). An unauthenticated remote attacker can trick a victim user into submitting malicious HTML or JavaScript code through a crafted URL or form input, which the application reflects back to the user's browser without proper sanitization, leading to arbitrary script execution in the victim's session.

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 Unisphere is accessibleAttempt to access the Unisphere web interface via HTTPS on port 443. Check if the login page loads at your Unisphere URL.Affected if Unisphere is reachable and responds to HTTP/HTTPS requests, indicating the web interface is active.
-
Identify Unity or UnityVSA versionLog into the Unisphere web interface as an administrator. Navigate to the About or Settings section to view the software version. Alternatively, access the service console and run: 'svcinfo -c' or check the version file at /etc/version if accessible via service account.Affected if The displayed version is a version number less than 4.3.1.1525703027.
-
Compare version against vulnerable rangeTake the version identified in the previous step and compare it numerically against 4.3.1.1525703027. Any version string that sorts lower than this value (e.g., 4.3.1.100, 4.2.0.5, etc.) is in the vulnerable range.Affected if The installed version is less than 4.3.1.1525703027, placing it within the affected range.
-
Assess Unisphere network exposureDetermine if Unisphere is accessible from external or untrusted networks. Check firewall rules, NAT configurations, or VPN policies that allow direct access to the Unisphere web port from outside the trusted internal network.Affected if Unisphere is exposed directly to untrusted networks without authentication proxy or VPN, increasing the likelihood of exploitation.
You are affected if Unisphere is accessible and the installed Unity or UnityVSA version is lower than 4.3.1.1525703027.

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 data4.3.1.1525703027
Apply the relevant Dell EMC security patch or upgrade Unity/UnityVSA to a version that addresses this vulnerability. As a compensating control, disable Unisphere access from untrusted networks and implement web application firewall rules to detect and block XSS payloads.
