Forskeren axi0mX har fundet<\/a><\/noindex> en s\u00e5rbarhed i bootrom-laderen af Apple-enheder, der fungerer i den allerf\u00f8rste bootfase og derefter overf\u00f8rer kontrollen til iBoot. S\u00e5rbarheden har f\u00e5et navnet checkm8 og muligg\u00f8r fuld kontrol over enheden. Den offentliggjorte exploit kan potentielt bruges til at omg\u00e5 firmware-verifikation (Jailbreak), organisere dual-boot af andre OS og forskellige versioner af iOS. <\/p>\n

Problemet er bem\u00e6rkelsesv\u00e6rdigt, fordi Bootrom ligger i NAND-hukommelse, der kun er tilg\u00e6ngelig for l\u00e6sning, hvilket ikke tillader at l\u00f8se problemet i allerede udgivne enheder (s\u00e5rbarheden kan kun rettes i nye produktioner). Problemet viser sig i SoC fra A5 til A11, der bruges i produkter fremstillet fra 2011 til 2017, fra iPhone 4S til modellerne iPhone 8 og X. <\/p>\n

En prelimin\u00e6r version af koden til udnyttelse af s\u00e5rbarheden er allerede integreret i det \u00e5bne (GPLv3) v\u00e6rkt\u00f8jss\u00e6t ipwndfu<\/a><\/noindex>, der er designet til at fjerne bindingen til Apple-firmwares. Exploiten er i \u00f8jeblikket begr\u00e6nset til funktioner til at lave dumps af SecureROM, dekryptere n\u00f8gler til firmwares med iOS og aktivere JTAG. En fuld automatiseret jailbreak af den seneste iOS-udgave er mulig, men er endnu ikke gennemf\u00f8rt, da den kr\u00e6ver yderligere arbejde. I \u00f8jeblikket er exploiten allerede tilpasset for SoC s5l8947x, s5l8950x, s5l8955x, s5l8960x, t8002, t8004, t8010, t8011 og t8015, og vil i fremtiden blive udvidet til at inkludere s5l8940x, s5l8942x, s5l8945x, s5l8747x, t7000, t7001, s7002, s8000, s8001, s8003 og t8012.<\/p>\n
