Le vulnerabilit\u00e0 consentono a un attaccante di infiltrarsi nel canale di comunicazione crittografato attraverso un attacco MITM. L'attacco non richiede la presenza di un certificato valido. <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/it\/ssl-sertifikat\/\"   title=\"SSL\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"2299\">SSL<\/a>-si certificati e pu\u00f2 essere condotta contro sistemi che richiedono l'autenticazione del cliente tramite certificato. Nel contesto del server, l'attacco consente l'inserimento di una propria query SQL al momento dell'instaurazione della connessione crittografata tra il cliente e il server PostgreSQL. Nel contesto di libpq, la vulnerabilit\u00e0 permette all'attaccante di restituire al cliente una risposta falsa dal server. In combinazione, le vulnerabilit\u00e0 permettono di estrarre informazioni sulla password o su altri dati riservati del cliente trasmessi nelle fasi iniziali della connessione.    <\/p>\n<p>In aggiunta, si segnala la pubblicazione da parte di Yandex della nuova versione del proxy server Odyssey 1.2, progettato per mantenere un pool di connessioni aperte al database PostgreSQL e per organizzare la routizzazione delle richieste.
