CVE-2022-26866Network attack vector

Session theft via stored management-interface script

Published Jun 2, 2022 · Updated Sep 17, 2024

Stored XSS in Dell Technologies PowerStore before 2.1.1.0 allows remote authenticated users to run script in a victim's browser. The management application accepts malicious HTML or JavaScript into a trusted application data store and later renders that content without neutralization. Exploitation requires high privileges and a victim to access the stored data, enabling information disclosure, session theft, or client-side request forgery.
