In SAP NetWeaver (BI CONT ADDON) - versions 707, 737, 747, 757, an attacker can exploit a directory traversal flaw in a report to upload and overwrite files on the SAP server. Data cannot be read but if a remote attacker has sufficient (administrative) privileges then potentially critical OS files can be overwritten making the system unavailable.
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.
