The default configuration of Movable Type before 4.38, 5.0x before 5.07, and 5.1x before 5.13 supports the "mt:Include file=" attribute, which allows remote authenticated users to conduct directory traversal attacks and read arbitrary files by leveraging the template-designer role.
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.
