OpenText Document Sciences xPression (formerly EMC Document Sciences xPression) v4.5SP1 Patch 13 (older versions might be affected as well) is prone to Arbitrary File Read: /xAdmin/html/cm_datasource_group_xsd.jsp, parameter: xsd_datasource_schema_file filename. In order for this vulnerability to be exploited, an attacker must authenticate to the application first.
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.
