Une faille WiFi d\u00e9couverte par un chercheur Embedi, menace la s\u00e9curit\u00e9 de 6,2 milliards d'ordinateurs, smartphones, routeurs et autres appareils disposant de certaines puces WiFi sous le syst\u00e8me d'exploitation embarqu\u00e9 ThreadX – que l'on trouve par exemple dans les consoles PS4 et Xbox One. Cette faille permet potentiellement d'ex\u00e9cuter \u00e0 distance du code arbitraire. La faille serait en outre exploitable m\u00eame lorsque les appareils ne sont connect\u00e9s \u00e0 aucun r\u00e9seau. Des mises \u00e0 jour correctives sont en cours d'\u00e9laboration.<\/strong><\/p>\n

\"bug<\/p>\n

Apr\u00e8s le WPA 2<\/a>, une nouvelle faille menace la s\u00e9curit\u00e9 des appareils connect\u00e9s en WiFi. Dans un rapport la firme Embedi\u00a0montre que le SoC de certains modules WiFi, en particulier les SoC Marvell WiFi FullMAC et les SoC compatibles avec le syst\u00e8me embarqu\u00e9 ThreadX, sont vuln\u00e9rables. Plusieurs bugs critiques laissent ainsi les pirates prendre \u00e0 distance le contr\u00f4le d'un appareil embarquant ces modules, sans qu'il n'y ait besoin, localement, de la moindre interaction utilisateur. Les modules WiFi pr\u00e9sents dans de nombreux appareils sont des syst\u00e8mes int\u00e9gr\u00e9s avec leur propre syst\u00e8me d'exploitation. Les appareils les plus vuln\u00e9rables embarquent des modules WiFi dits FullMAC, qui prennent en charge localement – sans l'aide du syst\u00e8me d'exploitation de la machine – certaines fonctionnalit\u00e9s avanc\u00e9es comme le scan de r\u00e9seaux sans fil. Au total, 6,2 milliards d'appareils – ordinateurs, routeurs, smartphones et consoles de jeux vid\u00e9o – sont menac\u00e9s par cette faille.<\/p>\n
