CVE-2020-35170
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 Unisphere for PowerMax versions prior to 9.1.0.9, Dell EMC Unisphere for PowerMax versions prior to 9.0.2.16, and Dell EMC PowerMax OS 5978.221.221 and 5978.479.479 contain a Cross-Site Scripting (XSS) vulnerability. An authenticated malicious user may potentially exploit this vulnerability to inject javascript code and affect other authenticated users’ sessions.
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 confidenceStored Cross-Site Scripting (XSS) vulnerability in Dell EMC Unisphere for PowerMax allows authenticated users to inject malicious JavaScript code that executes in the sessions of other authenticated users. The vulnerability affects Unisphere versions prior to 9.1.0.9 and 9.0.2.16, and PowerMax OS versions 5978.221.221 and 5978.479.479.

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 Dell Unisphere for PowerMax is deployedIdentify Unisphere instances in your environment by scanning for the web application (typically on ports 8443, 443, or 8080) or by checking Dell/EMC asset inventoriesAffected if Unisphere is not installed in your environment (not affected)
-
Check Unisphere versionLog into the Unisphere web interface and navigate to About or Settings to view the version, or use the Unisphere CLI command 'about' or 'unisphere -version' if availableAffected if The version is less than 9.1.0.24, or is 9.2.x less than 9.2.0.6, or is 9.0.2.x less than 9.0.2.16
-
Check PowerMax OS versionAccess the PowerMax storage array via Unisphere or use the storage array CLI command 'sysctl -a' or 'show version' to retrieve the PowerMax OS versionAffected if The PowerMax OS version is exactly 5978.221.221 or 5978.479.479
-
Verify web interface authentication is enabledConfirm that Unisphere requires user authentication to access the management consoleAffected if Authentication is disabled (prerequisite for exploitation not met)
-
Check for stored XSS injection pointsReview Unisphere configuration for any user-supplied input fields (such as naming, descriptions, or comments) that are stored and displayed to other usersAffected if Input fields exist that accept and display user-provided content without sanitization
You are affected if Unisphere for PowerMax is deployed AND the Unisphere version falls in the vulnerable ranges (< 9.1.0.24, 9.2.x < 9.2.0.6, or 9.0.2.x < 9.0.2.16) OR the PowerMax OS version is exactly 5978.221.221 or 5978.479.479, AND the web interface is accessible with authentication enabled.

From vendor data9.1.0.249.2.0.6
Upgrade Dell EMC Unisphere for PowerMax to version 9.1.0.9 or 9.0.2.16 or later, and ensure PowerMax OS is updated to versions beyond 5978.221.221 and 5978.479.479.
