In questo articolo esamineremo una vulnerabilit\u00e0 molto interessante nel sistema operativo \u00abnostrano\u00bb Astra Linux, e quindi, iniziamo...<\/p>\n

\"Vulnerabilit\u00e0<\/a><\/noindex>
\nAstra Linux \u00e8 un sistema operativo di specializzazione basato su kernel Linux, creato per la protezione complessiva delle informazioni e per la creazione di sistemi automatizzati sicuri.<\/p>\n

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

    \n
  1. l'edizione di uso generale \u2014 Common Edition \u2014 \u00e8 destinata a piccole e medie imprese, istituzioni educative;<\/li>\n
  2. l'edizione di uso speciale \u2014 Special Edition \u2014 \u00e8 destinata a sistemi automatizzati in esecuzione protetta, che elaborano informazioni con livello di riservatezza \u00abassolutamente riservato\u00bb incluso.<\/li>\n<\/ol>\n

    \nInizialmente, la vulnerabilit\u00e0 nel blocco dello schermo \u00e8 stata scoperta nel sistema operativo Astra Linux Common Edition v2.12, che si manifesta quando il computer \u00e8 in stato bloccato e, 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 con successo realizzata 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 stata effettuata una blocco della stazione, cambiando l'estensione della finestra della stazione):<\/p>\n

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

    \"Vulnerabilit\u00e0
    \n
    \nIn generale, si pu\u00f2 concludere che lo sfruttamento di questa falla permetterebbe di accedere in modo furtivo al contenuto dei documenti (inclusi quelli a accesso limitato), aperti sul desktop di una stazione bloccata con Astra Linux, il che porterebbe a una fuga di questo tipo di informazioni.
