Na pocz\u0105tku czerwca 2026 roku badacze bezpiecze\u0144stwa cybernetycznego z firmy Calif (przy u\u017cyciu agenta AI Codex) odkryli now\u0105 wersj\u0119 ataku HTTP\/2 Bomb, kt\u00f3ry dzia\u0142a nawet z jednego urz\u0105dzenia klienckiego maj\u0105cego po\u0142\u0105czenie internetowe o pr\u0119dko\u015bci 100 Mbit\/s.<\/p>\n

Atak sk\u0142ada si\u0119 z dw\u00f3ch etap\u00f3w:<\/p>\n

    \n
  1. \n

    Manipulacja kompresj\u0105 HPACK: W protokole HTTP\/2 nag\u0142\u00f3wki s\u0105 kompresowane za pomoc\u0105 tabeli HPACK. Napastnik wysy\u0142a niemal pusty nag\u0142\u00f3wek, ale przy pomocy setek tysi\u0119cy instrukcji zmusza serwer<\/a> do dekompresji i nieustannego odnoszenia si\u0119 do tego samego malutkiego elementu. To powoduje lawinowy wzrost zu\u017cycia pami\u0119ci serwera<\/a>.<\/p>\n<\/li>\n

  2. \n

    Zablokowanie sterowania przep\u0142ywem (Flow Control): Po zape\u0142nieniu pami\u0119ci, przest\u0119pca ustawia rozmiar okna sterowania przep\u0142ywem (flow-control window) na 0. To zmusza serwer do wstrzymania wysy\u0142ania odpowiedzi, zatrzymuj\u0105c zaj\u0119t\u0105 pami\u0119\u0107, i utrzymywania po\u0142\u0105czenia otwartego przy pomocy sporadycznych 1-bajtowych zapyta\u0144.<\/p>\n<\/li>\n<\/ol>\n

    Zaledwie jeden klient w ci\u0105gu 10\u201320 sekund mo\u017ce wykorzysta\u0107 do 32\u201364 GB pami\u0119ci RAM. Poziom zu\u017cycia pami\u0119ci w r\u00f3\u017cnych serwerach HTTP waha si\u0119 od oko\u0142o 70 bajt\u00f3w na ka\u017cdy bajt w indeksie dla nginx, IIS i Pingora, do 4000 bajt\u00f3w w Apache httpd i 5700 w Envoy.<\/p>\n

    Na wra\u017cliwo\u015b\u0107 nara\u017cone s\u0105 praktycznie wszystkie g\u0142\u00f3wne realizacje serwer\u00f3w HTTP\/2 w konfiguracjach domy\u015blnych:
    \nNGINX, Apache HTTPD (modu\u0142 mod_http2), Microsoft IIS, Envoy, Cloudflare, Pingora<\/p>\n

    Wra\u017cliwo\u015b\u0107 zosta\u0142a naprawiona w nginx 1.29.8 (przy u\u017cyciu dyrektywy max_headers z freenginx, domy\u015blnie pozwalaj\u0105cej na przetwarzanie nie wi\u0119cej ni\u017c 1000 nag\u0142\u00f3wk\u00f3w), Envoy 1.35.11 i 1.36.7 (mutable_max_request_headers_kb i max_headers_count), Appache mod_http2 2.0.41. Jak dot\u0105d nie ma poprawek dla Microsoft IIS i Cloudflare Pingora.<\/p>\n

    Serwer HTTP Angie nie jest podatny na t\u0119 wra\u017cliwo\u015b\u0107, poniewa\u017c wdro\u017cy\u0142 ochron\u0119 przed tego rodzaju atakami ju\u017c w wersji 1.8.0, wydanej w 2024 roku.<\/p>\n
