CVE-2019-13139: Docker build code execution


Severity

High

Vendor

Pivotal

Description

Pivotal Container Service (1.4.x versions prior to 1.4.3) depends on a vulnerable version of docker (versions prior to 18.09.4), where an attacker who is capable of supplying or manipulating the build path for the "docker build" command would be able to gain command execution. An issue exists in the way "docker build" processes remote git URLs, and results in command injection into the underlying "git clone" command, leading to code execution in the context of the user executing the "docker build" command. This occurs because git ref can be misinterpreted as a flag.
