GitHub har avsl\u00f6jat information om en s\u00e5rbarhet som g\u00f6r det m\u00f6jligt att f\u00e5 tillg\u00e5ng till inneh\u00e5llet i milj\u00f6variabler som anv\u00e4nds i containrar i arbetsinfrastrukturen. S\u00e5rbarheten identifierades av en deltagare i programmet Bug Bounty, som \u00e4r ber\u00e4ttigad till bel\u00f6ning f\u00f6r att hitta s\u00e4kerhetsproblem. Problemet p\u00e5verkar b\u00e5de tj\u00e4nsten GitHub.com och konfigurationer av GitHub Enterprise Server (GHES) som k\u00f6rs p\u00e5 anv\u00e4ndarsystem. <\/p>\n

Analys av loggar och granskning av infrastrukturen har inte visat n\u00e5gra tecken p\u00e5 utnyttjande av s\u00e5rbarheten tidigare f\u00f6rutom aktiviteten fr\u00e5n forskaren som rapporterade problemet. Trots detta har infrastrukturen genomf\u00f6rt en ers\u00e4ttning av alla krypteringsnycklar och autentiseringsuppgifter som kan ha potentiellt blivit komprometterade vid ett utnyttjande av s\u00e5rbarheten av en angripare. Ers\u00e4ttningen av interna nycklar ledde till driftst\u00f6rningar f\u00f6r vissa tj\u00e4nster mellan 27 och 29 december. Administrat\u00f6rer p\u00e5 GitHub har f\u00f6rs\u00f6kt att ta h\u00e4nsyn till de misstag som gjorts vid g\u00e5rdagens uppdatering av nycklar som p\u00e5verkar kunder. <\/p>\n

Bland annat har GPG-nyckeln, som anv\u00e4nds f\u00f6r att certifiera den digitala signaturen av commits som skapats via GitHubs webbredigerare vid godk\u00e4nnande av pull-f\u00f6rfr\u00e5gningar p\u00e5 webbplatsen eller via verktyget Codespace, uppdaterats. Den gamla nyckeln upph\u00f6rde att g\u00e4lla den 16 januari klockan 23:00 Moskvatid, och ist\u00e4llet anv\u00e4nds en ny nyckel sedan ig\u00e5r. Fr\u00e5n och med den 23 januari kommer alla nya commits som signeras med den gamla nyckeln inte att markeras som verifierade p\u00e5 GitHub-webbplatsen. <\/p>\n

Den 16 januari uppdaterades ocks\u00e5 de offentliga nycklar som anv\u00e4nds f\u00f6r att kryptera anv\u00e4ndardata som skickas via API till GitHub Actions, GitHub Codespaces och Dependabot. Anv\u00e4ndare som anv\u00e4nder GitHubs offentliga nycklar f\u00f6r lokal verifiering av commits och kryptering av \u00f6verf\u00f6rd data rekommenderas att s\u00e4kerst\u00e4lla att de har uppdaterat GitHubs GPG-nycklar och att deras system forts\u00e4tter att fungera efter nyckelarbetet. <\/p>\n

GitHub har redan \u00e5tg\u00e4rdat s\u00e5rbarheten p\u00e5 GitHub.com och sl\u00e4ppt en produktuppdatering f\u00f6r GHES 3.8.13, 3.9.8, 3.10.5 och 3.11.3, d\u00e4r korrigering f\u00f6r CVE-2024-0200 (os\u00e4ker anv\u00e4ndning av reflektioner som leder till kodexekvering eller anv\u00e4ndardefinierade metoder p\u00e5 serversidan) noteras. servern<\/a>). En attack mot lokala installationer av GHES kan ha utf\u00f6rts om angriparen hade ett konto med r\u00e4ttigheter att hantera organisationen (organisationens \u00e4gare).
