Arbitrary Read-Write Access Vulnerability in Docker's 'docker cp' Command

CVE-2018-15664 · MEDIUM Severity

AV:L/AC:H/AU:N/C:C/I:C/A:C

In Docker through 18.06.1-ce-rc2, the API endpoints behind the 'docker cp' command are vulnerable to a symlink-exchange attack with Directory Traversal, giving attackers arbitrary read-write access to the host filesystem with root privileges, because daemon/archive.go does not do archive operations on a frozen filesystem (or from within a chroot).
