The remote host is running Beanwebb's Guestbook.

This set of CGI has two vulnerabilities :

	- Anyone can access the admin page (admin.php)
	- It is vulnerable to cross site scripting attacks (in add.php)
	
	
An attacker may use these flaws to steal the cookies of your users
or to inject fake information in the guestbook.	


Solution : Delete this package
Risk factor : Low";
