In WebAccess/SCADA, Versions 8.3.5 and prior, a path traversal vulnerability is caused by a lack of proper validation of a user-supplied path prior to use in file operations. An attacker can leverage this vulnerability to delete files while posing as an administrator.
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.
