The remote CGI '/cgi-bin/webfind.exe' is vulnerable to
a buffer overflow when given a too long 'keywords' argument.

This problem allows an attacker to execute arbitrary code
as root on this host.

Solution : upgrade to WebSitePro 2.5 or delete this CGI
Risk factor : High";

Le CGI distant '/cgi-bin/webfind.exe' est vulnérable à
un dépassement de buffer lorsqu'on lui donne un argument
'keywords' trop long.

Ce problème permet à un pirate d'executer du code arbitraire
sur ce serveur.

Solution : mettez website pro à jour en version 2.5 ou effacez de CGI
Facteur de risque : Elevé";
