CVE-2021-34079Public exploit

Arbitrary command execution via crafted ports entry

Published Jun 1, 2022 · Updated Aug 4, 2024

OS command injection in Mintzo Docker-Tester 1.2.1 and earlier allows attackers to execute arbitrary commands via a crafted compose file. DockerCompose.getExternalPort inserts the parsed ports value into a docker-compose port command that execComposeCommand runs through a shell without validation. Attackers must supply a crafted compose file to a process that invokes the package; commands run with that process account's permissions.
