SAP Business Process Automation (BPA) By Redwood, 9.0, 9.1, allows an attacker to exploit insufficient validation of path information provided by users, thus characters representing 'traverse to parent directory' are passed through to the file APIs.
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.
