Detecting 'Leaky Vessels' Exploitation in Docker and Kubernetes

On January 31st 2024, Snyk announced the discovery of four vulnerabilities in Kubernetes and Docker. For Kubernetes, the vulnerabilities are specific to the runc CRI. Successful exploitation allows an attacker to escape the container and gain access to the host operating system. To exploit these vulnerabilities, an attacker will need to control the Dockerfile when the containers are built.

Buildkit mount cache race: Build-time race condition container breakout (CVE-2024-23651)

Snyk has discovered a vulnerability in all versions of Docker Buildkit <=v0.12.4, as used by the Docker engine. The exploitation of this issue can result in container escape to the underlying host OS when building an image using a malicious Dockerfile or upstream image (i.e. when using FROM). This issue has been assigned CVE-2024-23651.

Vulnerability: runc process.cwd and leaked fds container breakout (CVE-2024-21626)

Snyk has discovered a vulnerability in all versions of runc <=1.1.11, as used by the Docker engine, along with other containerization technologies such as Kubernetes. Exploitation of this issue can result in container escape to the underlying host OS, either through executing a malicious image or building an image using a malicious Dockerfile or upstream image (i.e., when using FROM). This issue has been assigned the CVE-2024-21626.

Leaky Vessels: Docker and runc container breakout vulnerabilities (January 2024)

Snyk security researcher Rory McNamara, with the Snyk Security Labs team, identified four vulnerabilities — dubbed "Leaky Vessels" — in core container infrastructure components that allow container escapes. An attacker could use these container escapes to gain unauthorized access to the underlying host operating system from within the container.

CSRF Attacks: Risk Analysis, Protection, and Anti-CSRF Tokens
