EPSS: 3.4% probability of exploitation in the next 30 days
Public exploit or detection template: yes
Published: 2019-05-23 · updated 2026-06-17
Weakness: CWE-362

Description

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).

Affected products

Docker Engine: 17.06.0-ce, 17.06.0-ce-rc1, 17.06.0-ce-rc2, 17.06.0-ce-rc3, 17.06.0-ce-rc4, 17.06.0-ce-rc5 (+58)
