Description

A flaw was found in tripleo-ansible. Due to an insecure default configuration, the permissions of a sensitive file are not sufficiently restricted. This flaw allows a local attacker to use brute force to explore the relevant directory and discover the file, leading to information disclosure of important configuration details from the OpenStack deployment.

• 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.
• CWE-276Incorrect Default PermissionsDuring installation, installed file permissions are set to allow anyone to modify those files.
• CWE-732Incorrect Permission Assignment for Critical ResourceThe product specifies permissions for a security-critical resource in a way that allows that resource to be read or modified by unintended actors.
