Description
LuCI is the OpenWrt Configuration Interface. Versions prior to both 24.10.5 and 25.12.0, contain a stored XSS vulnerability in the wireless scan modal, where SSID values from scan results are rendered as raw HTML without any sanitization. The wireless.js file in the luci-mod-network package passes SSIDs via a template literal to dom.append(), which processes them through innerHTML, allowing an attacker to craft a malicious SSID containing arbitrary HTML/JavaScript. Exploitation requires the user to actively open the wireless scan modal (e.g., to connect to a Wi-Fi access point or survey nearby channels), and only affects OpenWrt versions newer than 23.05/22.03 up to the patched releases (24.10.6 and 25.12.1). The issue has been fixed in version LuCI 26.072.65753~068150b.
Analysis
A stored cross-site scripting (XSS) vulnerability exists in the OpenWrt LuCI web interface where malicious JavaScript code embedded in Wi-Fi network names (SSIDs) can execute when users open the wireless scan modal. The vulnerability affects OpenWrt versions newer than 23.05/22.03 up to 24.10.5 and 25.12.0, allowing attackers within wireless range to compromise users who scan for available networks. …
