GitHub ujawni\u0142 informacje o podatno\u015bci, kt\u00f3ra umo\u017cliwia dost\u0119p do zawarto\u015bci zmiennych \u015brodowiskowych wystawionych w kontenerach wykorzystywanych w infrastrukturze roboczej. Podatno\u015b\u0107 zosta\u0142a wykryta przez uczestnika programu Bug Bounty, kt\u00f3ry ubiega si\u0119 o nagrod\u0119 za znalezienie problem\u00f3w z bezpiecze\u0144stwem. Problem dotyczy zar\u00f3wno serwisu GitHub.com, jak i konfiguracji GitHub Enterprise Server (GHES) dzia\u0142aj\u0105cych na systemach u\u017cytkownik\u00f3w. <\/p>\n

Analiza log\u00f3w i audyt infrastruktury nie wykaza\u0142y \u015blad\u00f3w wykorzystania podatno\u015bci w przesz\u0142o\u015bci, poza aktywno\u015bci\u0105 badacza, kt\u00f3ry zg\u0142osi\u0142 problem. Niemniej jednak w infrastrukturze zainicjowano wymian\u0119 wszystkich kluczy szyfrowania oraz danych uwierzytelniaj\u0105cych, kt\u00f3re mog\u0142y zosta\u0107 potencjalnie skompromitowane w przypadku wykorzystania podatno\u015bci przez napastnika. Wymiana kluczy wewn\u0119trznych spowodowa\u0142a zak\u0142\u00f3cenia w dzia\u0142aniu niekt\u00f3rych us\u0142ug od 27 do 29 grudnia. Administratorzy GitHub starali si\u0119 uwzgl\u0119dni\u0107 pope\u0142nione b\u0142\u0119dy podczas wczorajszej aktualizacji kluczy, dotycz\u0105cych klient\u00f3w. <\/p>\n

Mi\u0119dzy innymi zaktualizowano klucz GPG, u\u017cywany do cyfrowego podpisywania commit\u00f3w tworzonych za po\u015brednictwem edytora webowego GitHub podczas akceptowania pull-request\u00f3w na stronie lub przez narz\u0119dzie Codespace. Stary klucz przesta\u0142 dzia\u0142a\u0107 16 stycznia o godzinie 23:00 czasu moskiewskiego, a od wczoraj u\u017cywany jest nowy klucz. Pocz\u0105wszy od 23 stycznia, wszystkie nowe commity podpisane poprzednim kluczem nie b\u0119d\u0105 oznaczone na stronie GitHub jako zweryfikowane. <\/p>\n

16 stycznia zaktualizowano r\u00f3wnie\u017c otwarte klucze, u\u017cywane do szyfrowania danych przesy\u0142anych przez u\u017cytkownik\u00f3w za po\u015brednictwem API do GitHub Actions, GitHub Codespaces i Dependabot. U\u017cytkownikom, kt\u00f3rzy stosuj\u0105 do lokalnej weryfikacji commit\u00f3w oraz szyfrowania przesy\u0142anych danych otwarte klucze nale\u017c\u0105ce do GitHub, zaleca si\u0119 upewnienie, \u017ce zaktualizowali klucze GPG GitHub, a ich systemy nadal dzia\u0142aj\u0105 po wymianie kluczy. <\/p>\n

Firma GitHub ju\u017c usun\u0119\u0142a podatno\u015b\u0107 na stronie GitHub.com i wyda\u0142a aktualizacj\u0119 produktu GHES 3.8.13, 3.9.8, 3.10.5 oraz 3.11.3, w kt\u00f3rej zaznaczone jest poprawienie CVE-2024-0200 (niebezpieczne wykorzystanie refleksji, prowadz\u0105ce do wykonania kodu lub metod kontrolowanych przez u\u017cytkownika po stronie) serwera<\/a>). Atak na lokalne instalacje GHES mog\u0142a by\u0107 przeprowadzona, je\u015bli napastnik posiada\u0142 konto z uprawnieniami w\u0142a\u015bciciela organizacji (organization owner).
