I denna artikel kommer vi att unders\u00f6ka en mycket intressant s\u00e5rbarhet i det \"inhemska\" operativsystemet Astra Linux, s\u00e5 l\u00e5t oss b\u00f6rja...<\/p>\n

\"S\u00e5rbarhet<\/a><\/noindex>
\nAstra Linux \u00e4r ett specialiserat operativsystem baserat p\u00e5 Linux-k\u00e4rnan, som skapats f\u00f6r att skydda information och bygga s\u00e4kra automatiserade system.<\/p>\n

Tillverkaren utvecklar tv\u00e5 grundversioner av Astra Linux \u2014 Common Edition (allm\u00e4nt syfte) och dess modifiering Special Edition (s\u00e4rskilt syfte):<\/p>\n

    \n
  1. Allm\u00e4n version \u2014 Common Edition \u2014 \u00e4r avsedd f\u00f6r sm\u00e5 och medelstora f\u00f6retag, utbildningsinstitutioner;<\/li>\n
  2. Speciell version \u2014 Special Edition \u2014 \u00e4r avsedd f\u00f6r automatiserade system i en s\u00e4kerhetsklass, som hanterar information med s\u00e4kerhetsklass \"hemlig\" eller h\u00f6gre.<\/li>\n<\/ol>\n

    \nS\u00e5rbarheten i sk\u00e4rml\u00e5set uppt\u00e4cktes ursprungligen i operativsystemet Astra Linux Common Edition v2.12, och den upptr\u00e4der n\u00e4r datorn \u00e4r l\u00e5st och sk\u00e4rmuppl\u00f6sningen \u00e4ndras. Speciellt i virtuella milj\u00f6er (VMWare, Oracle Virtualbox) visas hela skrivbordets inneh\u00e5ll utan att beh\u00f6va autentisera sig. <\/p>\n

    Denna s\u00e5rbarhet har ocks\u00e5 framg\u00e5ngsrikt \u00e5terskapats p\u00e5 Astra Linux Special Edition v1.5. Det kan finnas en m\u00f6jlighet att f\u00e5 information \u00e4ven fr\u00e5n fysiska maskiner genom att anv\u00e4nda flera sk\u00e4rmar med olika uppl\u00f6sningar.<\/p>\n

    Nedan finns en video med en demonstration p\u00e5 Astra Linux Special Edition v1.5 (stationen l\u00e5stes, och f\u00f6nstrets storlek \u00e4ndrades):<\/p>\n

    \"S\u00e5rbarhet
    \n
    \nSk\u00e4rmdump fr\u00e5n videon (datafragment p\u00e5 skrivbordet):<\/p>\n

    \"S\u00e5rbarhet
    \n
    \nSammanfattningsvis kan man dra slutsatsen att utnyttjandet av denna s\u00e5rbarhet g\u00f6r det m\u00f6jligt att diskret f\u00e5 tillg\u00e5ng till dokumentens inneh\u00e5ll (inklusive begr\u00e4nsad information), \u00f6ppna p\u00e5 skrivbordet p\u00e5 den l\u00e5sta stationen med Astra Linux, vilket kan leda till l\u00e4ckage av denna typ av information.
