De Librem One-service, gericht op gebruik op smartphones Librem 5<\/a><\/noindex>, direct na de lancering<\/a><\/noindex> naar voren een kritieke probleem<\/a><\/noindex> met de beveiliging, die het project ondermijnt dat wordt gepresenteerd als een veilig platform voor privacybescherming. De kwetsbaarheid is gevonden in de Librem Chat-service en stelde gebruikers in staat om in de chat in te loggen als elke gebruiker, zonder kennis van de authenticatieparameters.<\/p>\n

In de gebruikte backend-code voor autorisatie via LDAP (matrix-appservice-ldap3) voor het Matrix-netwerk is een fout gemaakt error<\/a><\/noindex>, die ook is overgenomen in de code van de werkservice Librem One. In plaats van de regel «result, _ = yield self._ldap_simple_bind» werd «result = yield self._ldap_simple_bind» opgegeven, wat het voor elke gebruiker zonder authenticatie mogelijk maakte om in de chat in te loggen met elke identificatie. De ontwikkelaars van het Matrix-project die de fout hebben gemaakt, hebben dit toegelaten. bevestigen<\/a><\/noindex>, dat het probleem alleen optrad in de master-tak «matrix-appservice-ldap3», en niet in de releases, maar dat de probleemregel in de repository stond. aanwezig<\/a><\/noindex> al sinds 2016 (mogelijk zijn de voorwaarden voor het exploiteren van het probleem pas ontstaan na enkele recente wijzigingen).<\/p>\n

De ge\u00efntroduceerde set Librem One-diensten vereist een betaalde abonnementsdienst ($7.99 per maand of $71.91 per jaar), maar is gebaseerd op bestaande open projecten die zijn hernoemd<\/a><\/noindex> voor distributie onder het Librem-merk. Bijvoorbeeld, Librem Chat is een hernoemde Matrix-client Riot<\/a><\/noindex>, Librem Social is gebaseerd op Tusky<\/a><\/noindex>, Librem Mail is hernoemd uit K-9<\/a><\/noindex>, Librem Tunnel is ontleend aan Ics-openvpn<\/a><\/noindex>. Servercomponenten zijn gebaseerd op
\n Postfix en Dovecot voor Librem Mail, Matrix<\/a><\/noindex> voor Librem Chat en Mastodon<\/a><\/noindex> voor Librem Social. De reden voor het aanbieden van applicaties onder andere namen is de wens om verschillende gedecentraliseerde diensten op basis van open standaarden (Matrix, ActivityPub, IMAP) te verzamelen onder \u00e9\u00e9n herkenbaar merk. <\/p>\n
