Buildroot'i komplekteerimiss\u00fcsteemis, mis on suunatud Linuxi k\u00e4ivitamis\u00f6kos\u00fcsteemide loomisele sisseehitatud s\u00fcsteemidele, on tuvastatud kuus haavatavust, mis v\u00f5imaldavad kesktee r\u00fcnnaku (MITM) k\u00e4igus muuta genereeritud s\u00fcsteemipilte v\u00f5i k\u00e4ivitada koodi komplekteerimiss\u00fcsteemi tasemel. Haavatavused on k\u00f5rvaldatud Buildroot'i versioonides 2023.02.8, 2023.08.4 ja 2023.11. <\/p>\n

Esimesed viis haavatavust (CVE-2023-45841, CVE-2023-45842, CVE-2023-45838, CVE-2023-45839, CVE-2023-45840) m\u00f5jutavad paketih\u00e4\u00e4lte kontrollimise koodi. Probleemid seonduvad v\u00f5imalusega kasutada HTTP-d failide allalaadimiseks ja m\u00f5nede paketide kontrollfailide puudumisega, mis v\u00f5imaldab andmepakettide sisu valeallika kaudu muuta. serverilt<\/a> (n\u00e4iteks kui kasutaja on \u00fchendatud r\u00fcnnaku all oleva traadita v\u00f5rgu kaudu). <\/p>\n

Eelk\u00f5ige laaditi pakkide aufs ja aufs-util allalaadimine toimus HTTP kaudu ning neid ei kontrollitud hashide j\u00e4rgi. Hashid puudusid ka pakkidele riscv64-elf-toolchain, versal-firmware ja mxsldr, mis vaikimisi laaditi alla HTTPS kaudu, kuid probleemide korral langetati otsus laadida neid kr\u00fcpteerimata hostilt http:\/\/sources.buildroot.net. Failide puudumisel nimega '.hash' pidas Buildroot t\u00f6\u00f6riist edukaks kontrollimiseks ja t\u00f6\u00f6tles allalaaditud pakette, sealhulgas rakendas pakettidesse kuuluvad plaastrid ja k\u00e4ivitas ehitusskeeme. R\u00fcndajal oli v\u00f5imalus allalaaditavaid pakette asendada, lisades neisse oma plaastrid v\u00f5i ehitusfailid Makefiles, mis v\u00f5imaldas muuta l\u00f5plikku pilti v\u00f5i ehitusautomaatika skripte ning saavutada oma koodi t\u00e4itmine. <\/p>\n

Kuues haavatavus (CVE-2023-43608) tuleneb BR_NO_CHECK_HASH_FOR funktsionaalsuse rakenduse veast, mis v\u00f5imaldab h\u00e4\u00e4letuskontrolli keelduda valitud paketide jaoks. M\u00f5ned paketid, nagu Linuxi tuum, U-Boot ja versal-firmware, lubasid viimaste versioonide allalaadimist, mille jaoks polnud veel h\u00e4\u00e4letuskontrolle genereeritud. Nende versioonide jaoks rakendati BR_NO_CHECK_HASH_FOR valikut, mis keelas h\u00e4\u00e4letuskontrolli. Andmed laaditi alla HTTPS kaudu, kuid vaikimisi kasutati t\u00f5rke korral allalaadimise tagasip\u00f6\u00f6ramiseks allalaadimist source.buildroot.net ilma kr\u00fcptimiseta protokolli http:\/\/ kaudu. R\u00fcndaja sai MITM-r\u00fcnnaku k\u00e4igus blokeerida \u00fchenduse HTTPS-serveriga ning sel juhul tagastati allalaadimine http:\/\/sources.buildroot.net.
