Description

containerd is an open-source container runtime. Versions prior to 2.3.2, 2.2.5 and 2.1.9 contain a bug where the CRI plugin restores container.log from a checkpoint image without validating a symlinked path. This could result in reading an arbitrary file on the host via kubectl logs. This issue has been fixed in versions 2.3.2, 2.2.5 and 2.1.9.

Techniques & Countermeasures

  • CWE-61•UNIX Symbolic Link (Symlink) Following

    The product, when opening a file or directory, does not sufficiently account for when the file is a symbolic link that resolves to a target outside of the intended control sphere. This could allow an attacker to cause the product to operate on unauthorized files.
