CRI-O-s, mis on runtime isoleeritud konteinerite haldamiseks, tuvastati kriitiline haavatavus (CVE-2022-0811), mis v\u00f5imaldab \u00fcletada isoleerituse ja k\u00e4ivitada oma koodi host-s\u00fcsteemi pool. Kui kasutatakse CRI-O-d containerd ja Docker'i asemel konteinerite k\u00e4ivitamiseks, mis t\u00f6\u00f6tavad Kubernetes platvormi all, saab r\u00fcndaja kontrollida mis tahes s\u00f5lme Kubernetes klastris. R\u00fcnnaku teostamiseks on piisavalt \u00f5igusi oma konteineri k\u00e4ivitamiseks Kubernetes klastris. <\/p>\n

Haavatavus tuleneb v\u00f5imalusest muuta kernel'i sysctl-parameetrit \"kernel.core_pattern\" (\"\/proc\/sys\/kernel\/core_pattern\"), millele ei olnud juurdep\u00e4\u00e4s blokeeritud, kuigi see ei kuulu muutmiseks turvaliste parameetrite hulka, mis kehtivad ainult jooksva konteineri nimes. Selle parameetri abil saab konteineri kasutaja muuta Linuxi kernel'i k\u00e4itumist core-failide t\u00f6\u00f6tlemisel host-\u00fcmbruses ja saab k\u00e4ivitada juhuslikke k\u00e4ske root'i \u00f5igustes hostis, m\u00e4\u00e4rates t\u00f6\u00f6tleja t\u00fc\u00fcbi \"|\/bin\/sh -c 'k\u00e4sklused'\". <\/p>\n

Probleem ilmnes alates CRI-O versioonist 1.19.0 ja on k\u00f5rvaldatud uuendustes 1.19.6, 1.20.7, 1.21.6, 1.22.3, 1.23.2 ja 1.24.0. Jaotustes ilmnes probleem Red Hat OpenShift Container Platform ja openSUSE\/SUSE toodetes, mille repositooriates on olemas paketid cri-o.
