CMSimple 5.4 is vulnerable to Directory Traversal. The vulnerability exists when a user changes the file name to malicious file on config.php leading to remote code execution.
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.
