CVE-2019-18578
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 XtremIO XMS versions prior to 6.3.0 contain a stored cross-site scripting vulnerability. A low-privileged malicious remote user of XtremIO may exploit this vulnerability to store malicious HTML or JavaScript code in application fields. When victim users access the injected page through their browsers, the malicious code may be executed by the web browser in the context of the vulnerable web application.
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 confidenceA stored cross-site scripting vulnerability exists in Dell EMC XtremIO XMS versions prior to 6.3.0. A low-privileged remote attacker can inject malicious HTML or JavaScript code into application input fields, which persists in the application and executes in the browsers of other users who access the injected content.

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.
-
Determine the installed XMS versionLog into the XtremIO XMS web management console and navigate to the About or System Information page. Alternatively, use the XMS CLI and run the 'show-version' or 'system-info' command to retrieve the installed software version.Affected if The displayed version is any release prior to 6.3.0 (for example, 6.0.x, 6.1.x, 6.2.x)
-
Confirm XMS web interface is accessibleAttempt to reach the XMS web interface via HTTPS on the management IP address or hostname. Verify the login page loads successfully.Affected if The XMS web interface is reachable over the network and accepts authentication
-
Identify user account privilegesReview the user accounts configured in XMS via the Administration or Users section of the management console. Note which accounts have low-privileged roles versus administrator roles.Affected if Low-privileged or non-administrative user accounts exist in the system
The environment is affected if the installed XMS version is below 6.3.0 and the web interface is accessible to low-privileged users who can inject malicious script into application input fields.
Generated from the published advisory. Verify against your own configuration.
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.
dbcve · scoped6.3.0
Upgrade XtremIO XMS to version 6.3.0 or later to remediate this stored XSS vulnerability. Consider implementing additional input validation and output encoding as defense-in-depth while planning the upgrade.
