Subject: NPDS <= 5.10 - Multiple SQL injections

[|Description:|]
Security holes were found in NPDS 5.10.

N°1: Sql Injection in cookies (File Mainfile.php lines 655 to 691).
No check is carried out on nicknames or Id which can allow an attacker
to modify a SQL request so as to obtain data.

N°2: SQL Injection due to a bad use of "X_FORWARDED_FOR" (file Mainfile.php lines 88 to 110).
NPDS uses the HTTP header "X_FORWARDED_FOR" which normally contains the IP adress
of a person using a non anonymous proxy. This Ip address is used in a SQL resquest without appropriate
filtering, and an attacker can define "X_FORWARDED_FOR" insering malicious SQL code.

[|Exploit:|]
http://www.aeroxteam.fr/exploit-NPDS-5.10.txt

[|Solution:|]
N°1: File mainfile.php, add after line 665:
$cookie[0] = inval($cookie[0);
$cookie[1] = addslashes($cookie[1]);
$cookie[2] = addslashes($cookie[2]);

N°2: Replace fonction "getip" (mainfile.php) by:
function getip() {
	return $_SERVER['REMOTE_ADDR'];
}
