No servi\u00e7o Librem One, voltado para uso em smartphones Librem 5<\/a><\/noindex>, logo ap\u00f3s o lan\u00e7amento<\/a><\/noindex> surgiu um problema cr\u00edtico<\/a><\/noindex> de seguran\u00e7a, que descredita o projeto apresentado como uma plataforma segura para garantir a privacidade. A vulnerabilidade encontrada no servi\u00e7o Librem Chat permitia que qualquer usu\u00e1rio tivesse acesso ao chat, sem conhecer as credenciais de autentica\u00e7\u00e3o.<\/p>\n

No c\u00f3digo de backend utilizado para autentica\u00e7\u00e3o via LDAP (matrix-appservice-ldap3) na rede Matrix, foi cometida uma erro<\/a><\/noindex>, que foi transferido tamb\u00e9m para o c\u00f3digo do servi\u00e7o ativo Librem One. Em vez da linha «result, _ = yield self._ldap_simple_bind», foi especificado «result = yield self._ldap_simple_bind», o que permitia a qualquer usu\u00e1rio sem autentica\u00e7\u00e3o entrar no chat com qualquer identificador. Os desenvolvedores do projeto Matrix que cometeram o erro afirmam<\/a><\/noindex>, que o problema ocorria apenas na branch master «matrix-appservice-ldap3», e n\u00e3o nas vers\u00f5es, mas na linha problem\u00e1tica no reposit\u00f3rio est\u00e3o presentes<\/a><\/noindex> estava presente desde 2016 (possivelmente as condi\u00e7\u00f5es para explora\u00e7\u00e3o do problema s\u00f3 surgiram ap\u00f3s algumas mudan\u00e7as recentes).<\/p>\n

O conjunto de servi\u00e7os Librem One proposto implica uma assinatura paga ($7,99 por m\u00eas ou $71,91 por ano), mas, ao mesmo tempo, foi utilizado como base para os clientes m\u00f3veis e processadores de servidor projetos abertos existentes, que foram renomeados<\/a><\/noindex> para serem distribu\u00eddos sob a marca Librem. Por exemplo, o Librem Chat \u00e9 um cliente Matrix renomeado, Riot<\/a><\/noindex>o Librem Social \u00e9 baseado em Tusky<\/a><\/noindex>o Librem Mail \u00e9 renomeado de K-9,<\/a><\/noindex>o Librem Tunnel foi emprestado de Ics-openvpn.<\/a><\/noindex>Os componentes do servidor s\u00e3o baseados em
\n Postfix e Dovecot para Librem Mail, Matrix<\/a><\/noindex> para Librem Chat e Mastodon<\/a><\/noindex> para Librem Social. A raz\u00e3o apresentada para fornecer os aplicativos sob nomes diferentes \u00e9 a inten\u00e7\u00e3o de reunir diversos servi\u00e7os descentralizados baseados em padr\u00f5es abertos sob uma marca reconhec\u00edvel (Matrix, ActivityPub, IMAP). <\/p>\n
