A Path Traversal vulnerability was discovered in MOPCMS through 2018-11-30, leading to deletion of unexpected critical files. The exploitation point is in the "column management" function. The path added to the column is not verified. When a column is deleted by an attacker, the corresponding directory is deleted, as demonstrated by ./ to delete the entire web site.
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.
