W PackageKit, warstwie D-Bus, kt\u00f3ra unifikuje operacje zarz\u0105dzania pakietami, zidentyfikowano luk\u0119 Pack2TheRoot (CVE-2026-41651), kt\u00f3ra umo\u017cliwia nieuprzywilejowanemu u\u017cytkownikowi zainstalowanie lub usuni\u0119cie dowolnego pakietu oraz uzyskanie dost\u0119pu roota do systemu. Problem wyst\u0119puje od wersji 1.0.2 (2014 rok) i zosta\u0142 usuni\u0119ty w wersji PackageKit 1.3.5. <\/p>\n

Problem\u0119 wykryli badacze z firmy Deutsche Telekom przy pomocy modelu AI Claude Opus. Przygotowano dzia\u0142aj\u0105cy exploit, kt\u00f3ry dzia\u0142a w wi\u0119kszo\u015bci dystrybucji z PackageKit, ale szczeg\u00f3\u0142owe informacje o podatno\u015bci maj\u0105 by\u0107 opublikowane p\u00f3\u017aniej, aby da\u0107 u\u017cytkownikom czas na zaktualizowanie swoich system\u00f3w. Mo\u017cliwo\u015b\u0107 wykorzystania podatno\u015bci zademonstrowano w Ubuntu Desktop 18.04\/24.04.4\/26.04, Ubuntu Server 22.04 \u2014 24.04, Debian Desktop 13.4, RockyLinux Desktop 10.1 i Fedora 43 Desktop\/Server. Status usuwania podatno\u015bci w dystrybucjach mo\u017cna oceni\u0107 na tych stronach (je\u015bli strona jest niedost\u0119pna, oznacza to, \u017ce deweloperzy dystrybucji jeszcze nie zacz\u0119li rozwi\u0105zywa\u0107 problemu): Debian, Ubuntu, SUSE, RHEL, Gentoo, Arch, Fedora, FreeBSD. <\/p>\n

Luka jest spowodowana stanem wy\u015bcigu podczas przetwarzania flag transakcji w tle PackageKit, co pozwala na zmian\u0119 parametr\u00f3w operacji w momencie pomi\u0119dzy przej\u015bciem autoryzacji a rozpocz\u0119ciem operacji z pakietem. Napastnik mo\u017ce wys\u0142a\u0107 \u017c\u0105danie D-Bus do wykonania operacji dozwolonej dla nieuprzywilejowanego u\u017cytkownika, a nast\u0119pnie natychmiast wys\u0142a\u0107 powt\u00f3rne \u017c\u0105danie D-Bus. Je\u015bli powt\u00f3rne \u017c\u0105danie przyjdzie przed faktycznym rozpocz\u0119ciem wykonywania dozwolonej operacji, mo\u017cna nadpisa\u0107 flagi ju\u017c rozpocz\u0119tej transakcji i zmieni\u0107 zacachowane informacje. <\/p>\n

W ten spos\u00f3b ju\u017c rozpocz\u0119ta dozwolona transakcja zostanie wykonana z nieoryginalnymi, ale zmienionymi parametrami, kt\u00f3re zosta\u0142y przekazane w drugim \u017c\u0105daniu. Zmieniaj\u0105c informacje o instalowanym pakiecie mo\u017cna zamiast dozwolonego pakietu zainstalowa\u0107 dowolny inny pakiet, w tym pakiet lokalnie zapisany przez napastnika. Instalacja pakietu odbywa si\u0119 z uprawnieniami roota, wi\u0119c w celu uzyskania dost\u0119pu roota w systemie, napastnik mo\u017ce doda\u0107 do pakietu w\u0142asny skrypt, kt\u00f3ry jest automatycznie uruchamiany przed lub po instalacji.
