CyberRota Analysis

AI-Generated

Windows Container on Windows (WCOW) workers using BuildKit are vulnerable due to a failure to detect NTFS directory junctions within the cache root, allowing untrusted build processes to access arbitrary host files. This could lead to unauthorized data exposure and potential compromise of sensitive information on the host system. Organizations utilizing WCOW with BuildKit should prioritize addressing this vulnerability to mitigate risks associated with untrusted user builds.

Original NVD Description

BuildKit's cache mount source= selector on Windows Container on Windows (WCOW) workers does not detect NTFS directory junctions placed inside the cache root. A build authored by an untrusted user on a WCOW-configured BuildKit daemon can read arbitrary host files reachable to the BuildKit daemon process.
