ClipSoft REXPERT 1.0.0.527 and earlier version allows arbitrary file creation via a POST request with the parameter set to the file path to be written. This can be an executable file that is written to in the arbitrary directory. User interaction is required to exploit this vulnerability in that the target must visit a malicious web page.
Weaknesses in this category are related to the management of permissions, privileges, and other security features that are used to perform access control.
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.
