Yes, Containers Are Terrific, But Watch the Security Risks

Containers revolutionized the development process, acting as a cornerstone for DevOps initiatives, but containers bring complex security risks that are not always obvious. Organizations that don't mitigate these risks are vulnerable to attack. In this article, we outline how containers contribute...

Arbitrary File Write in Libcontainer

Libcontainer 1.6.0, as used in Docker Engine, allows local users to escape containerization "mount namespace breakout" and write to arbitrary file on the host system via a symlink attack in an image when respawning a container...

The vulnerability of software for performing virtualization at the operating system level, also known as containerization, Singularity, arises from insufficient checking of unusual or exceptional states. This allows attackers to gain access to confidential data, compromise its integrity, and cause service failures.

The vulnerability of software for performing virtualization at the operating system level, also known as containerization, is related to improper checking of the return value of functions. Exploiting this vulnerability can allow a malicious actor to gain access to confidential data, compromise it...

CVE-2021-41091 concerns Moby (Docker Engine). A bug in the Docker Engine data directory (/var/lib/docker) left subdirectories with weak permissions, enabling unprivileged host users to traverse contents and, if containers held executables with elevated bits (e.g., setuid), to discover and run tho...

Center for Threat-Informed Defense teams up with Microsoft, partners to build the ATT&CK® for Containers matrix

The MITRE ATT&CK® for Containers matrix was published today, establishing an industry knowledge base of attack techniques associated with containerization and related technologies that are increasingly more ubiquitous in the current computing landscape. Microsoft is happy to have contributed and...

Cryptomining containers caught coining cryptocurrency covertly

In traditional software development, programmers code an application in one computing environment before deploying it to a similar, but often slightly different environment. This leads to bugs or errors that only show up when the software is deployed—exactly when you need them least. To solve for...

Who Contains the Containers?

Posted by James Forshaw, Project Zero This is a short blog post about a research project I conducted on Windows Server Containers that resulted in four privilege escalations which Microsoft fixed in March 2021. In the post, I describe what led to this research, my research process, and insights...
