CVE-2019-25015Public exploit

Stored XSS via unescaped wireless SSID

Published Jan 21, 2021 · Updated Aug 5, 2024

Stored XSS in LuCI in OpenWrt 18.06.0 through 18.06.4 allows attackers to execute JavaScript via a crafted wireless SSID. The wireless-join form inserts the SSID into its title without HTML escaping, while the interface overview passes the stored name as a raw element child. Execution requires a user to select the malicious network or manually store its SSID and then open the affected LuCI view.
