GitHub har offentliggjort oplysninger om en s\u00e5rbarhed, der g\u00f8r det muligt at f\u00e5 adgang til indholdet af milj\u00f8variabler, der er indstillet i containere brugt i arbejdsmilj\u00f8et. S\u00e5rbarheden blev opdaget af en deltager i programmet Bug Bounty, som er berettiget til en bel\u00f8nning for at finde sikkerhedsproblemer. Problemet p\u00e5virker b\u00e5de tjenesten GitHub.com og konfigurationer af GitHub Enterprise Server (GHES), der k\u00f8rer p\u00e5 brugernes systemer. <\/p>\n
Analyse af logs og revision af infrastrukturen viste ingen tegn p\u00e5 udnyttelse af s\u00e5rbarheden tidligere, bortset fra aktiviteten fra forskeren, der rapporterede problemet. Ikke desto mindre blev der iv\u00e6rksat en udskiftning af alle krypteringsn\u00f8gler og legitimationsoplysninger i infrastrukturen, som potentielt kunne v\u00e6re kompromitteret, hvis s\u00e5rbarheden blev udnyttet af en angriber. Udskiftningen af de interne n\u00f8gler f\u00f8rte til forstyrrelser i nogle tjenester fra den 27. til den 29. december. GitHub-administratorer fors\u00f8gte at tage hensyn til beg\u00e5ede fejl ved den igangv\u00e6rende opdatering af n\u00f8glerne, der p\u00e5virker kunderne. <\/p>\n
Blandt andet blev GPG-n\u00f8glen opdateret, som bruges til at signere digitale signaturer af commits oprettet via GitHub's web-editor ved accept af pull-anmodninger p\u00e5 webstedet eller gennem v\u00e6rkt\u00f8jet Codespace. Den gamle n\u00f8gle oph\u00f8rte med at v\u00e6re gyldig den 16. januar kl. 23:00 Moskva-tid, og fra i g\u00e5r anvendes en ny n\u00f8gle. Fra den 23. januar vil alle nye commits, der er signeret med den gamle n\u00f8gle, ikke blive markeret som verificerede p\u00e5 GitHub-webstedet. <\/p>\n
Den 16. januar blev ogs\u00e5 de \u00e5bne n\u00f8gler opdateret, der bruges af brugeren til at kryptere data sendt via API til GitHub Actions, GitHub Codespaces og Dependabot. Brugere, der anvender GitHub's \u00e5bne n\u00f8gler til lokal verifikation af commits og kryptering af overf\u00f8rte data, opfordres til at sikre sig, at de har opdateret GitHub GPG-n\u00f8glerne, og at deres systemer forts\u00e6tter med at fungere efter udskiftningen af n\u00f8glerne. <\/p>\n
GitHub har allerede l\u00f8st s\u00e5rbarheden p\u00e5 GitHub.com og har udgivet produktopdateringer til GHES 3.8.13, 3.9.8, 3.10.5 og 3.11.3, i hvilken d\u00e6kning CVE-2024-0200 er angivet (usikker brug af refleksioner, der f\u00f8rer til udf\u00f8relse af kode eller brugerdefinerede metoder p\u00e5 siden). server<\/a>). Et angreb p\u00e5 lokale installationer af GHES kunne v\u00e6re udf\u00f8rt, hvis en angriber havde en konto med administrationsrettigheder for organisationen (organization owner).
