The vulnerability exists within processing of sendmail.php in Schneider Electric U.motion Builder software versions prior to v1.3.4. The applet allows callers to select arbitrary files to send to an arbitrary email address.
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.
