files.php in Vivvo CMS 4.1.5.1 allows remote attackers to conduct directory traversal attacks and read arbitrary files via the file parameter with "logs/" in between two . (dot) characters, which is filtered into a "../" sequence.
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.
