\u00cen instrumentarul pentru lansarea containerelor izolate runc, utilizat \u00een Docker \u0219i Kubernetes, a fost identificat\u0103 o vulnerabilitate (CVE-2021-30465) care permite accesul din container la sistemul de fi\u0219iere principal al mediului gazd\u0103. Prin manipularea leg\u0103turilor simbolice, se poate preg\u0103ti o configura\u021bie aparent inofensiv\u0103 a containerului, care va duce la montarea bind a unui FS extern \u00een interiorul containerului. Problema a fost rezolvat\u0103 \u00een actualizarea runc 1.0.0-rc95. <\/p>\n

Pentru exploatarea vulnerabilit\u0103\u021bii, atacatorul trebuie s\u0103 aib\u0103 capacitatea de a lansa containere cu puncte de montare suplimentare \u00een configura\u021bie (de exemplu, problema se reproduce \u00een medii bazate pe Kubernetes, \u00een care utilizatorii pot lansa propriile lor containere). Din cauza existen\u021bei unei feronii temporale \u00eentre verificare \u0219i utilizare a punctelor de montare pe parti\u021bii, partajate cu alte containere, atacatorul poate profita de o stare de competi\u021bie \u00een timpul lans\u0103rii containerului \u0219i poate \u00eenlocui catalogul utilizat la montarea \u00een container cu o leg\u0103tur\u0103 simbolic\u0103 c\u0103tre o zon\u0103 din afara r\u0103d\u0103cinii FS-ului containerului.
