Forskaren axi0mX har hittat<\/a><\/noindex> en s\u00e5rbarhet i bootrom f\u00f6r Apple-enheter, som fungerar i det allra f\u00f6rsta skedet av uppstarten och sedan \u00f6verl\u00e4mnar kontrollen till iBoot. S\u00e5rbarheten har f\u00e5tt namnet checkm8 och m\u00f6jligg\u00f6r full kontroll \u00f6ver enheten. Den publicerade exploiten kan potentiellt anv\u00e4ndas f\u00f6r att kringg\u00e5 verifiering av firmware (Jailbreak), organisera dual-booting av andra operativsystem och olika versioner av iOS. <\/p>\n

Problemet \u00e4r anm\u00e4rkningsv\u00e4rt eftersom Bootrom finns i minnet som endast kan l\u00e4sas (NAND), vilket inte till\u00e5ter att problemet \u00e5tg\u00e4rdas i redan utgivna enheter (s\u00e5rbarheten kan endast r\u00e4ttas till i nya parti av enheter). Problemet uppt\u00e4cks i SoC fr\u00e5n A5 till A11, som anv\u00e4nds i produkter tillverkade mellan 2011 och 2017, fr\u00e5n iPhone 4S till iPhone 8 och X. <\/p>\n

En prelimin\u00e4r kodversion f\u00f6r att utnyttja s\u00e5rbarheten har redan integrerats i det \u00f6ppna (GPLv3) verktyget ipwndfu<\/a><\/noindex>, som \u00e4r avsett f\u00f6r att kringg\u00e5 Apple-firmware. Exploiten \u00e4r f\u00f6r n\u00e4rvarande begr\u00e4nsad till funktionerna f\u00f6r att skapa dump av SecureROM, dekryptera nycklar f\u00f6r firmware med iOS och aktivera JTAG. En fullst\u00e4ndigt automatiserad jailbreak av den senaste versionen av iOS \u00e4r m\u00f6jlig, men har inte genomf\u00f6rts \u00e4n, eftersom det kr\u00e4ver ytterligare arbete. Just nu har exploiten redan anpassats f\u00f6r SoC s5l8947x, s5l8950x, s5l8955x, s5l8960x, t8002, t8004, t8010, t8011 och t8015, och kommer i framtiden att ut\u00f6kas med st\u00f6d f\u00f6r s5l8940x, s5l8942x, s5l8945x, s5l8747x, t7000, t7001, s7002, s8000, s8001, s8003 och t8012.<\/p>\n
