[|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.


[|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']; }
