Summary
Docker is prone to a remote code execution vulnerability.
Insight
Insight
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.
Affected Software
Affected Software
Docker prior version 18.09.4.
Detection Method
Detection Method
Checks if a vulnerable version is present on the target host.
