Firefox Androidi jaoks tuvastatud<\/a><\/noindex> t\u00f5sine haavatavus<\/a><\/noindex> protokolli rakendamisel SSDP<\/a><\/noindex>, mis kasutatakse kohalike v\u00f5rkude teenuste tuvastamiseks. Haavatavus v\u00f5imaldab r\u00fcndajal, kes on samas kohalikes v\u00f5i traadita v\u00f5rkudes, vastata Firefoxi kontrollk\u00fcsimustele UPnP XML «LOCATION» s\u00f5numiga koos intent-k\u00e4ske<\/a><\/noindex>, millega saab avada brauseris suvalist URI-d v\u00f5i kutsuda esile teiste rakenduste k\u00e4itlejad. <\/p>\n

Probleem ilmneb kuni v\u00e4ljaandmiseni Firefox Androidi jaoks 68.11.0<\/a><\/noindex> ja on k\u00f5rvaldatud versioonis Firefox Androidi jaoks 79, st vanad klassikalised versioonid Firefox Androidi jaoks on haavatavad ning probleemi lahendamiseks on vajalik \u00fcleminek uuele toimetusele<\/a><\/noindex> brauserist (Fenix), mis kasutab GeckoView mootorit, mis on rajatud Firefox Quantum tehnoloogiatele ja raamatukogude kogumile Mozilla Android Components<\/a><\/noindex>. Desktopi s\u00fcsteemide Firefoxi versioonid ei ole puudutatud.<\/p>\n

Haavatavuse testimiseks on ette valmistatud<\/a><\/noindex> t\u00f6\u00f6tav protot\u00fc\u00fcp eksploidist. R\u00fcnnak toimub ilma kasutaja sekkumiseta, piisab, kui haavatav Firefox Androidi brauser on mobiilseadmes avatud ja et ohver asuks r\u00fcndaja SSDP-serveriga samas alamv\u00f5rgus. <\/p>\n

Firefox Androidi jaoks saadab perioodiliselt laialivalguvas re\u017eiimis (multicast UDP) SSDP-s\u00f5numeid kohalikesv\u00f5rkude seadmete, n\u00e4iteks multimeedia m\u00e4ngijate ja nutitelerite, kohaloleku m\u00e4\u00e4ramiseks. K\u00f5ik seadmed kohalikus v\u00f5rgus saavad nendest s\u00f5numitest andmeid ja v\u00f5ivad vastata. Tavalises re\u017eiimis tagastab seade lingi XML-faili asukoha juurde, mis sisaldab UPnP tugeva seadme teavet. R\u00fcnnaku korral v\u00f5ib XML-i lingi asemel edastada URI Androidi intent-k\u00e4skude koosseisuga. <\/p>\n

Intent-k\u00e4skude abil on v\u00f5imalik suunata kasutajat phishing-lehtedele v\u00f5i edastada link xpi-failile (brauser pakub v\u00f5imalust installida laiendust). Kuna r\u00fcndealti vastuseid ei piira miski, v\u00f5ivad nad proovida kasutajat \u00fcle ujutada installimisettepanekute v\u00f5i pahatahtlike lehtedega, lootes, et kasutaja eksib ja klikib pahatahtliku paketi installimisele. Lisaks juhuslike linkide avamisele brauseris saab intent-k\u00e4sku kasutada ka sisu t\u00f6\u00f6tlemiseks teistes Android-rakendustes, n\u00e4iteks saab avada e-kirja \u0161ablooni e-posti kliendis (URI mailto:) v\u00f5i k\u00e4ivitada liidese k\u00f5ne tegemiseks (URI tel:).<\/p>\n
