Deweloperzy projektu PHP ostrzegli o kompromitacji repozytorium Git oraz o wykryciu dw\u00f3ch z\u0142o\u015bliwych commit\u00f3w, kt\u00f3re zosta\u0142y dodane 28 marca do repozytorium php-src w imieniu Rasmusa Lerdorfa, za\u0142o\u017cyciela PHP, oraz Nikity Popova, jednego z kluczowych deweloper\u00f3w PHP. <\/p>\n

Poniewa\u017c nie ma pewno\u015bci co do niezawodno\u015bci serwera, na kt\u00f3rym by\u0142o umieszczone repozytorium Git, deweloperzy zdecydowali, \u017ce utrzymanie infrastruktury Git w ich r\u0119kach stwarza dodatkowe ryzyka bezpiecze\u0144stwa i przenie\u015bli repozytorium referencyjne na platform\u0119 GitHub, kt\u00f3r\u0105 proponuje si\u0119 u\u017cywa\u0107 jako g\u0142\u00f3wn\u0105. Wszystkie zmiany nale\u017cy teraz wysy\u0142a\u0107 do GitHub, a nie do git.php.net, a tak\u017ce w przypadku rozwoju mo\u017cna teraz korzysta\u0107 z interfejsu webowego GitHub. <\/p>\n

W pierwszym z\u0142o\u015bliwym commicie, udaj\u0105cym poprawk\u0119 b\u0142\u0119du w pliku ext\/zlib\/zlib.c, wprowadzono zmiany uruchamiaj\u0105ce kod PHP przekazywany w nag\u0142\u00f3wku HTTP User Agent, je\u015bli jego zawarto\u015b\u0107 zaczyna si\u0119 od s\u0142owa \u201ezerodium\u201d. Gdy deweloperzy zauwa\u017cyli z\u0142o\u015bliw\u0105 zmian\u0119 i j\u0105 cofn\u0119li, w repozytorium pojawi\u0142 si\u0119 drugi commit, kt\u00f3ry zablokowa\u0142 dzia\u0142ania deweloper\u00f3w PHP i przywr\u00f3ci\u0142 z\u0142o\u015bliw\u0105 zmian\u0119. <\/p>\n

W dodanym kodzie znajduje si\u0119 linia \u201eREMOVETHIS: sold to zerodium, mid 2017\u201d, kt\u00f3ra mo\u017ce sugerowa\u0107, \u017ce od 2017 roku w kodzie znajduje si\u0119 inne, dobrze zamaskowane, z\u0142o\u015bliwe zmiany lub nieusuni\u0119ta luka, sprzedana firmie Zerodium, zajmuj\u0105cej si\u0119 zakupem luk 0-day (firma Zerodium odpowiedzia\u0142a, \u017ce nie kupowa\u0142a informacji o lukach w PHP). <\/p>\n

Obecnie brak szczeg\u00f3\u0142owych informacji na temat incydentu, zak\u0142ada si\u0119 jedynie, \u017ce zmiany zosta\u0142y dodane w wyniku w\u0142amania serwery<\/a> git.php.net, a nie kompromitacji poszczeg\u00f3lnych kont deweloper\u00f3w. Rozpocz\u0119to analiz\u0119 repozytorium w poszukiwaniu innych z\u0142o\u015bliwych zmian poza zidentyfikowanymi problemami. Do recenzji zaprasza si\u0119 wszystkich ch\u0119tnych, w przypadku wykrycia podejrzanych zmian nale\u017cy wys\u0142a\u0107 informacje na adres security@php.net. <\/p>\n

Je\u015bli chodzi o przej\u015bcie na GitHub, aby uzyska\u0107 dost\u0119p do zapisu w nowym repozytorium, uczestnicy rozwoju musz\u0105 do\u0142\u0105czy\u0107 do organizacji PHP. Osoby, kt\u00f3re nie s\u0105 w gronie deweloper\u00f3w PHP na GitHubie, powinny skontaktowa\u0107 si\u0119 z Nikiem Popowem pod adresem e-mail nikic@php.net. Dodatkowym wymogiem jest w\u0142\u0105czenie uwierzytelniania dwuetapowego. Po uzyskaniu odpowiednich uprawnie\u0144, aby zmieni\u0107 repozytorium, wystarczy wykona\u0107 polecenie \u201egit remote set-url origin git@github.com:php\/php-src.git\u201d. Dodatkowo rozwa\u017cane jest wprowadzenie obowi\u0105zkowego podpisywania commit\u00f3w cyfrowym podpisem dewelopera. Proponowane jest r\u00f3wnie\u017c zakazanie bezpo\u015bredniego wprowadzania zmian, kt\u00f3re nie przesz\u0142y wcze\u015bniejszej recenzji.
