Il problema \u00e8 stato classificato con un livello di gravit\u00e0 critico (10 su 10).         <\/p>\n<p>Uno dei ricercatori di sicurezza ha gi\u00e0 preparato un exploit funzionante per eseguire codice sui server SSH vulnerabili. \u00c8 interessante notare che, secondo il ricercatore, il codice \u00e8 stato creato utilizzando assistenti AI come GPT-4, Cursor e Sonnet, analizzando le modifiche apportate per correggere la vulnerabilit\u00e0, che include un test per verificare la risoluzione del problema.     <\/p>\n<p>La libreria del progetto Erlang\/OTP fornisce implementazioni pronte di client e <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/it\/server\/dts-los-angeles\/\"   title=\"server\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"3962\">server<\/a> SSH e SFTP, che supportano il protocollo SSH 2.0. \u00c8 possibile distinguere i server SSH problematici dal messaggio di intestazione \"SSH-2.0-Erlang\/versione\". I server SSH basati su Erlang\/OTP vengono utilizzati in sistemi specializzati, ad esempio, su dispositivi IoT e per il calcolo edge, e come strumento di debug: Erlang consente di attivare facilmente un server SSH per il debug remoto delle proprie applicazioni (si suppone che tale funzionalit\u00e0 di debug possa essere rimasta attivata in molti progetti scritti in Erlang). Il problema si manifesta anche negli strumenti di Elixir (realizzati sopra Erlang) e nel framework Phoenix basato su di esso, ma il server SSH in Phoenix non accetta richieste da reti esterne per impostazione predefinita.      <\/p>\n<p>La vulnerabilit\u00e0 \u00e8 causata da un errore nel codice di analisi dei messaggi, che fa s\u00ec che i messaggi SSH_MSG_CHANNEL_REQUEST, che consentono l'esecuzione del comando \"exec\", vengano elaborati in fase pre-autenticazione. Esempio di codice dall'exploit: command = 'file:write_file(\"\/lab.txt\", &lt;&gt;). return ( b\"\"  # SSH_MSG_CHANNEL_REQUEST + struct.pack('&gt;I', channel_id) + string_payload(\"exec\") + b\"\"  # want_reply = true + string_payload(command) )          <\/p>\n<p>La vulnerabilit\u00e0 \u00e8 stata risolta nelle versioni Erlang\/OTP-27.3.3, 26.2.5.11 e 25.3.2.20. \u00c8 possibile tenere traccia della risoluzione della vulnerabilit\u00e0 nelle distribuzioni alle seguenti pagine: Debian, Ubuntu, Fedora, SUSE\/openSUSE, RHEL, Arch, FreeBSD.<br \/>\n<br \/>Fonte: <a content=\"nofollow\"
