CVE-2021-37216Network attack vector

Data access and modification via reflected JavaScript

Published Aug 2, 2021 · Updated Sep 16, 2024

Reflected XSS in QSAN Storage Manager XN8008T and XN8024R allows remote attackers to inject JavaScript through header-page parameters. XN8008T 3.3.2 and earlier and XN8024R 3.1.5 and earlier return those parameters without filtering special characters, causing attacker-supplied script to execute in a user's browser. No login is required, but a user must interact with a crafted request; successful execution permits access to and modification of data available to that browser session.
