In questo articolo esamineremo una vulnerabilit\u00e0 molto interessante nel sistema operativo domestico Astra Linux, quindi iniziamo...<\/p>\n

\"Vulnerabilit\u00e0<\/a><\/noindex>
\nAstra Linux \u00e8 un sistema operativo di uso speciale basato sul kernel Linux, progettato per la protezione completa delle informazioni e la creazione di sistemi automatizzati sicuri.<\/p>\n

Il produttore sta sviluppando la versione base di Astra Linux \u2014 Common Edition (per uso generale) e la sua modifica Special Edition (per uso speciale):<\/p>\n

    \n
  1. la versione per uso generale \u2014 Common Edition \u2014 \u00e8 destinata alle piccole e medie imprese e alle istituzioni educative;<\/li>\n
  2. la versione per uso speciale \u2014 Special Edition \u2014 \u00e8 destinata a sistemi automatizzati in configurazione sicura, che trattano informazioni con un grado di segretezza 'top secret' incluso.<\/li>\n<\/ol>\n

    \nInizialmente, la vulnerabilit\u00e0 nel blocca schermo \u00e8 stata scoperta nel sistema operativo Astra Linux Common Edition v2.12, si manifesta quando il computer \u00e8 in stato bloccato e se in questo momento si cambia la risoluzione dello schermo. In particolare, negli ambienti virtuali (VMWare, Oracle Virtualbox), si verifica la visualizzazione completa del contenuto del desktop senza passare attraverso l'autenticazione. <\/p>\n

    Questa vulnerabilit\u00e0 \u00e8 stata anche sfruttata con successo su Astra Linux Special Edition v1.5. \u00c8 possibile che ci sia un modo per ottenere informazioni anche da macchine fisiche, utilizzando pi\u00f9 monitor con risoluzioni diverse.<\/p>\n

    Di seguito \u00e8 fornito un video dimostrativo su Astra Linux Special Edition v1.5 (\u00e8 stato bloccato il terminale, modificata la dimensione della finestra del terminale):<\/p>\n

    \"Vulnerabilit\u00e0
    \n
    \nScreenshot dal video (frammento di dati sul desktop):<\/p>\n

    \"Vulnerabilit\u00e0
    \n
    \nIn sintesi, si pu\u00f2 concludere che lo sfruttamento di questa falla consentir\u00e0 di visualizzare clandestinamente il contenuto dei documenti (inclusi quelli a accesso limitato) aperti sul desktop del terminale bloccato con Astra Linux, il che porter\u00e0 a una fuga di questo tipo di informazioni.
