Hacks

Researchers discovered a critical vulnerability in Docker that allows an attacker to take complete control of the host and the containers associated with it. The Docker vulnerability resides in the copy command (cp) used in containers platforms such as  Docker ,  Podman , and  Kubernetes . This command can be used to copy files & folders between the container and the local file system. The commands can be used like below: docker cp [OPTIONS] CONTAINER:SRC_PATH DEST_PATH|- docker cp [OPTIONS] SRC_PATH|- CONTAINER:DEST_PATH Docker Copy Command Vulnerability According to researchers, this is the first Docker cp command that leads to a full container escape after the runC vulnerability identified in February. The vulnerability can be exploited by the attacker if the docker already compromised with any previous vulnerabilities or if the user runs a malicious container image from an untrusted source. “If the user then executes the vulnerable cp command to ...
