Firefox Androidile tuvastatud<\/a><\/noindex> t\u00f5sine haavatavus<\/a><\/noindex> protokolli rakendamisel SSDP<\/a><\/noindex>, mis on m\u00f5eldud kohaliku v\u00f5rgu teenuste tuvastamiseks. Selle haavatavuse t\u00f5ttu saab r\u00fcndaja, kes asub samas kohalikus v\u00f5i traadita v\u00f5rgus, vastata Firefox'i kontrollk\u00fcsitlustele UPnP XML «LOCATION» s\u00f5numiga intent-k\u00e4skluste<\/a><\/noindex>, abil saab avada brauseris suvalise URI v\u00f5i kutsuda esile teiste rakenduste k\u00e4sitlejad. <\/p>\n

Probleem ilmneb kuni v\u00e4ljaandmiseni Firefox Androidile 68.11.0<\/a><\/noindex> ja on lahendatud versioonis Firefox Androidile 79, st vanemad klassikalised Firefoxi versioonid Androidile on haavatavad ja probleemi blokeerimiseks on vajalik \u00fcleminek uus versioon<\/a><\/noindex> brauserist (Fenix), mis kasutab GeckoView mootorit, mis p\u00f5hineb Firefox Quantum tehnoloogiatel ja komplektidel Mozilla Android Components<\/a><\/noindex>. Firefoxi t\u00f6\u00f6lauaversioonid ei ole probleemi all.<\/p>\n

Haavatavuse testimiseks on valmistatud<\/a><\/noindex> on t\u00f6\u00f6tav eksploitatsiooni protot\u00fc\u00fcp. R\u00fcnnak toimub ilma igasuguste kasutaja toiminguteta, piisab, et mobiilseadmest oleks k\u00e4ivitatud haavatav Firefox Androidi brauser ja et ohver oleks samas alams\u00fcsteemis r\u00fcndaja SSDP-serveriga. <\/p>\n

Firefox Androidille saadab aeg-ajalt laialdases re\u017eiimis (multicast UDP) SSDP-s\u00f5numeid, et tuvastada kohalikke v\u00f5rguseadmeid, n\u00e4iteks multimeedia m\u00e4ngijaid ja nutitelevisioone. K\u00f5ik seadmed kohalikus v\u00f5rgus saavad neid s\u00f5numeid ja v\u00f5ivad vastata. Tavalises re\u017eiimis saadab seade lingi XML-faili asukohale, mis sisaldab UPnP-d toetava seadme teavet. R\u00fcnnaku puhul v\u00f5ib lingi asemel edastada URI intent-k\u00e4skudega Androidile. <\/p>\n

Intent-k\u00e4skude abil saab suunata kasutajaid phishingu-lehtedele v\u00f5i edastada lingi xpi-failile (brauserid pakuvad laienduse installimist). Kuna r\u00fcndaja vastused ei ole millegagi piiratud, v\u00f5ib ta proovida kasutajat v\u00e4sitama, uputades brauserit pidevate installimisettepanekute v\u00f5i pahatahtlike saitidega, lootes, et kasutaja teeb vea ja kl\u00f5psab kahjustava paketi installimisel. Lisaks juhuslike linkide avamisele brauseris saab intent-k\u00e4skusid kasutada ka sisu t\u00f6\u00f6tlemiseks teistes Android-rakendustes, n\u00e4iteks saab avada e-kirja mall postikliendis (URI mailto:) v\u00f5i k\u00e4ivitada k\u00f5ne interface'i (URI tel:).<\/p>\n
