Description

OpenStack Ironic before 29.0.1 can write unintended files to a target node disk during image handling (if a deployment was performed via the API). A malicious project assigned as a node owner can provide a path to any local file (readable by ironic-conductor), which may then be written to the target node disk. This is difficult to exploit in practice, because a node deployed in this manner should never reach the ACTIVE state, but it still represents a danger in environments running with non-default, insecure configurations such as with automated cleaning disabled. The fixed versions are 24.1.3, 26.1.1, and 29.0.1.

• CWE-22Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
