CVE-2020-29496Network attack vector

Stored XSS via unsanitized Enduser data

Published Jan 4, 2021 · Updated Sep 17, 2024

Stored XSS in Dell Wyse Management Suite before 3.1 allows remote authenticated users to execute script in victims' browsers. The Enduser creation workflow stores attacker-supplied HTML or JavaScript and renders that data in the vulnerable application's browser context. Exploitation requires high privileges and a victim to view the saved data, enabling script-driven confidentiality and integrity impact without service interruption.
