Marc Newlin, kes avastas haavatavuse MouseJack<\/a> seitsme aasta eest avaldas ta teavet sarnase haavatavuse kohta (CVE-2023-45866)<\/a>, mis m\u00f5jutab Androidi, Linuxi, macOS-i ja iOS-i Bluetooth-l\u00e4bipaistmatust. See haavatavus v\u00f5imaldab kasutada n\u00e4iliselt seadmest sisestatud klahvivajutusi, simuleerides Bluetoothiga \u00fchendatud sisendseadet. Saades juurdep\u00e4\u00e4su klaviatuuri sisendile, saab r\u00fcndaja teha mitmesuguseid toiminguid, n\u00e4iteks k\u00e4ivitada s\u00fcsteemis k\u00e4ske, installida rakendusi ja suunata s\u00f5numeid.<\/p>\n

<\/noindex><\/noindex> <\/p>\n

Haavatavus tuleneb sellest, et Bluetooth-seadmete HID (Human Interface Device) draiverid v\u00f5imaldavad kaugperifeersete seadmete loomist ja kr\u00fcpteeritud \u00fchenduste seadistamist ilma autentimiseta. Sellised \u00fchendatud seadmed saavad edastada klaviatuuri teateid, mida HID-i virn t\u00f6\u00f6tleb, mis avab v\u00f5imaluse r\u00fcnnakuks HID-s\u00f5numite manipuleerimise teel, mida saab teostada ilma kasutaja sekkumiseta. Seda r\u00fcnnakut saab teostada kuni 100 meetri kauguselt ohvrist.<\/p>\n

Seadmete paarimise mehhanism ilma autentimiseta on m\u00e4\u00e4ratletud Bluetoothi spetsifikatsioonis ja s\u00f5ltuvalt Bluetoothi virna seadistustest v\u00f5imaldab see seadme \u00fchendamist kasutaja kinnitust saamata. N\u00e4iteks Linuxis, kui kasutatakse BlueZ-p\u00f5hist Bluetoothi virna, peab Bluetooth-adapter olema peidetud paarimise ja \u00fchendamise re\u017eiimis. Androidis piisab Bluetoothi toe lubamisest. iOS-is ja macOS-is peab edukaks r\u00fcnnakuks olema Bluetooth sisse l\u00fclitatud ning traadita klaviatuur \u00fchendatud.<\/p>\n

Sisendi manipuleerimise v\u00f5imalust on demonstreeritud Ubuntu 18.04, 20.04, 22.04 ja 23.10 BlueZ-p\u00f5hise Bluetoothi virnaga. ChromeOS ei ole haavatav, kuna selle Bluetoothi virna seaded ei v\u00f5imalda autentimiseta \u00fchendusi. Androidis m\u00f5jutab see haavatavus seadmeid, mille platvormi versioonid on vahemikus 4.2.2 kuni 14. macOS-is on haavatavust demonstreeritud MacBook Pro 2022 Apple M2 protsessoriga ja macOS 13.3.3 ning MacBook Air 2017 Intel protsessoriga ja macOS 12.6.7. iOS-is on haavatavust demonstreeritud iPhone SE-ga ja iOS 16.6. Lockdown-re\u017eiimi aktiveerimine ei paku kaitset r\u00fcnnaku eest macOS-is ja iOS-is.<\/p>\n

<\/p>\n

Linuxis on haavatavus k\u00f5rvaldatud<\/a> Bluez'i koodibaasis seadistades seade \"ClassicBondedOnly\" v\u00e4\u00e4rtuseks \"true\", aktiveeritakse turvare\u017eiim, mis lubab \u00fchenduste loomise alles p\u00e4rast sidumist. Varasemalt oli seade \"false\", mis v\u00e4hendas turvalisust teatud sisendseadmete \u00fchilduvuse tagamiseks.<\/p>\n

<\/noindex> <\/p>\n

Bluetoothe Fluoride'i virnas, mida kasutatakse uusimates Androidi versioonides, haavatavus on k\u00f5rvaldatud<\/a> n\u00f5udes k\u00f5igi kr\u00fcpteeritud \u00fchenduste jaoks autentimist. Androidile v\u00e4ljastati parandused ainult versioonide 11-14 jaoks. Pixel-seadmete jaoks k\u00f5rvaldas haavatavuse detsembri tarkvarauuendus. Androidi versioonides 4.2.2 kuni 10 j\u00e4\u00e4b haavatavus lahendamata.<\/p>\n
