Description

The Tutor LMS WordPress plugin before 4.0.6 does not validate a stored file path before using it to stream media, allowing users with the instructor role to read arbitrary files on the server, including files outside the web root. The readable files include the WordPress configuration file, which exposes the database credentials and the authentication keys and salts, so authentication cookies can be forged.

• 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.
