CVE-2024-24557 – Moby classic builder cache poisoning

https://notcve.org/view.php?id=CVE-2024-24557

Moby is an open-source project created by Docker to enable software containerization. The classic builder cache system is prone to cache poisoning if the image is built FROM scratch. Also, changes to some instructions (most important being HEALTHCHECK and ONBUILD) would not cause a cache miss. An attacker with the knowledge of the Dockerfile someone is using could poison their cache by making them pull a specially crafted image that would be considered as a valid cache candidate for some build steps. 23.0+ users are only affected if they explicitly opted out of Buildkit (DOCKER_BUILDKIT=0 environment variable) or are using the /build API endpoint. All users on versions older than 23.0 could be impacted. • https://github.com/moby/moby/commit/3e230cfdcc989dc524882f6579f9e0dac77400ae https://github.com/moby/moby/security/advisories/GHSA-xw73-rw38-6vjc • CWE-345: Insufficient Verification of Data Authenticity CWE-346: Origin Validation Error •
