CVE-2026-32721
HighSummary
LuCI, interfejs konfiguracyjny OpenWrt, zawiera podatność XSS typu stored w modalnym oknie skanowania sieci bezprzewodowej w wersjach przed 24.10.5 i 25.12.0. Wartości SSID z wyników skanowania są renderowane jako surowy HTML bez jakiejkolwiek sanitizacji, co umożliwia atakującemu wstrzyknięcie złośliwego kodu.
Risk Assessment
Podatność ta może prowadzić do wykonania złośliwego kodu JavaScript w przeglądarkach użytkowników, co stwarza ryzyko kradzieży danych lub przejęcia kontroli nad sesjami. Wymaga to jednak, aby użytkownik otworzył modalne okno skanowania sieci bezprzewodowej.
Recommendation
Zaleca się aktualizację do wersji LuCI 26.072.65753~068150b lub nowszej, aby usunąć tę podatność. Należy również rozważyć ograniczenie dostępu do funkcji skanowania sieci bezprzewodowej dla nieautoryzowanych użytkowników.

Original NVD description (English source)
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.
