\u00c8 stata rilevata una vulnerabilit\u00e0 critica (CVE-2023-27482) nella piattaforma di automazione domestica open source Home Assistant, che consente di eludere l'autenticazione e di ottenere accesso completo all'API privilegiata di Supervisor, attraverso la quale \u00e8 possibile modificare impostazioni, installare\/aggiornare software, gestire componenti aggiuntivi e backup. <\/p>\n

Il problema riguarda le installazioni in cui \u00e8 utilizzato il componente Supervisor e appare a partire dalle sue prime versioni (dal 2017). Ad esempio, la vulnerabilit\u00e0 \u00e8 presente negli ambienti Home Assistant OS e Home Assistant Supervised, ma non colpisce Home Assistant Container (Docker) e gli ambienti Python creati manualmente basati su Home Assistant Core. <\/p>\n

La vulnerabilit\u00e0 \u00e8 stata risolta nella versione Home Assistant Supervisor 2023.01.1. Inoltre, un workaround protettivo \u00e8 stato incluso nel rilascio di Home Assistant 2023.3.0. Nei sistemi in cui non \u00e8 possibile installare l'aggiornamento per bloccare la vulnerabilit\u00e0, si pu\u00f2 limitare l'accesso alla porta di rete del servizio web di Home Assistant dalle reti esterne. <\/p>\n

Il metodo di sfruttamento della vulnerabilit\u00e0 non \u00e8 ancora dettagliato (secondo gli sviluppatori, circa 1\/3 degli utenti ha installato l'aggiornamento e molti sistemi rimangono vulnerabili). Nella versione corretta, sotto forma di ottimizzazione, sono state apportate modifiche alla gestione dei token e delle richieste proxy, e sono stati aggiunti filtri per bloccare l'inserimento di query SQL, l'aggiunta del tag e l'uso di percorsi con '..\/' e '\/.\/'.
