Niekorzystny certyfikacji niekomercyjnej organizacji Let's Encrypt, kontrolowanej przez spo\u0142eczno\u015b\u0107 i udost\u0119pniaj\u0105cej certyfikaty nieodp\u0142atnie wszystkim zainteresowanym, og\u0142osi\u0142 przedwczesne odwo\u0142anie oko\u0142o dw\u00f3ch milion\u00f3w certyfikat\u00f3w TLS, co stanowi oko\u0142o 1% wszystkich aktywnych certyfikat\u00f3w tej organizacji certyfikacyjnej. Odwo\u0142anie certyfikat\u00f3w zosta\u0142o zainicjowane w zwi\u0105zku z wykryciem niezgodno\u015bci z wymaganiami specyfikacji w stosowanym w Let's Encrypt kodzie realizuj\u0105cym rozszerzenie TLS-ALPN-01 (RFC 7301, Application-Layer Protocol Negotiation). Nieprzestrzeganie zasad by\u0142o zwi\u0105zane z brakiem niekt\u00f3rych weryfikacji wykonywanych podczas ustalania po\u0142\u0105cze\u0144 na podstawie rozszerzenia TLS ALPN, stosowanego w HTTP\/2. Szczeg\u00f3\u0142owe informacje dotycz\u0105ce incydentu zostan\u0105 opublikowane po zako\u0144czeniu procesu odwo\u0142ania problematycznych certyfikat\u00f3w. <\/p>\n

26 stycznia o 03:48 (MSK) problem zosta\u0142 rozwi\u0105zany, jednak wszystkie certyfikaty, w przypadku kt\u00f3rych do weryfikacji wykorzystano metod\u0119 TLS-ALPN-01, postanowiono uzna\u0107 za niewa\u017cne. Wycofanie certyfikat\u00f3w rozpocznie si\u0119 28 stycznia o 19:00 (MSK). Do tego czasu u\u017cytkownikom korzystaj\u0105cym z metody weryfikacji TLS-ALPN-01 zaleca si\u0119 jak najszybsze zaktualizowanie swoich certyfikat\u00f3w, w przeciwnym razie zostan\u0105 one przedterminowo uznane za niewa\u017cne. <\/p>\n

Odpowiednie powiadomienia o konieczno\u015bci aktualizacji certyfikat\u00f3w zosta\u0142y wys\u0142ane na adresy e-mail. U\u017cytkownik\u00f3w korzystaj\u0105cych z narz\u0119dzi Certbot i dehydrated do uzyskania certyfikatu, przy u\u017cyciu ustawie\u0144 domy\u015blnych, problem nie dotkn\u0105\u0142. Metoda TLS-ALPN-01 jest wspierana w paczkach Caddy, Traefik, apache mod_md i autocert. Sprawdzi\u0107 poprawno\u015b\u0107 swoich certyfikat\u00f3w mo\u017cna przez wyszukiwanie identyfikator\u00f3w, numer\u00f3w seryjnych lub domen\u00f3w<\/a> w li\u015bcie problematycznych certyfikat\u00f3w. <\/p>\n

Poniewa\u017c zmiany dotycz\u0105 zachowania podczas weryfikacji metod\u0105 TLS-ALPN-01, do kontynuacji pracy mo\u017ce by\u0107 wymagane zaktualizowanie klienta ACME lub zmiana ustawie\u0144 (Caddy, bitnami\/bn-cert, autocert, apache mod_md, Traefik). Zmiany polegaj\u0105 na wymogu stosowania wersji TLS nie ni\u017cszej ni\u017c 1.2 (klienci nie b\u0119d\u0105 mogli korzysta\u0107 z TLS 1.1) oraz zaprzestaniu wsparcia dla OID 1.3.6.1.5.5.7.1.30.1, identyfikuj\u0105cego przestarza\u0142e rozszerzenie acmeIdentifier, wspierane tylko w wczesnych wersjach roboczych specyfikacji RFC 8737 (przy tworzeniu certyfikatu dozwolone jest teraz tylko OID 1.3.6.1.5.5.7.1.31, a klienci korzystaj\u0105cy z OID 1.3.6.1.5.5.7.1.30.1 nie b\u0119d\u0105 mogli uzyska\u0107 certyfikatu).
