CVE-2020-21161Public exploitNetwork attack vector

Cross-site scripting via unsanitized web input

Published Jun 27, 2022 · Updated Jul 9, 2026

Cross-site scripting in Ruckus Wireless ZoneDirector 9.8.3.0 allows remote attackers to execute script in a logged-in user's browser. Public records identify the vulnerable component only as the ZoneDirector web interface and do not disclose the specific parameter or handler that fails to sanitize attacker-controlled input. Exploitation requires a victim to follow or render the crafted web content; reported impact is browser-side confidentiality and integrity loss without service interruption.
