CVE-2019-18578Network attack vector

Stored script execution via unsanitized application fields

Published Mar 13, 2020 · Updated Sep 16, 2024

Stored XSS in Dell EMC XtremIO XMS before 6.3.0 allows remote authenticated users to execute script in another user's browser. Application fields persist attacker-supplied HTML or JavaScript and render it without adequate neutralization when a user opens the injected page. Low-privileged XtremIO access is required to store the payload, and a victim must view the affected page for browser-context execution.
