############################################

in the last week some researchers and me have found multiple
critical SQL injections in bcoos 1.0.10 and prior versions.

After a simple study/look of the source code of product
i have found a simple patch , this is not a oficial patch but it
still working fine ,before the vendor release a oficial patch or
a new release.

You can use this modification as a solution to mitigate all
SQL injections , only need to detect 'union' sql command.


##########################
Sample code
##########################
you need to add this code to all afected files ...


if (eregi("%20union%20", $lid) ||eregi(" union ", $lid) || eregi("\*union\*", $lid) || eregi("\+union\+", $lid) || eregi("\*", $lid))
{
echo "<br /><br /><div style=\"text-align: center;\"><big>This SQL injection is patched Now !!!</big></div><br /><br />";
redirect_header("index.php");
die();
}

###########################
patch mylinks/ratelink.php
############################

open ratelink.php and arround line 73 you have a 'else' like } else {

put the code just before the else condition like :

}
if (eregi("%20union%20", $lid) ||eregi(" union ", $lid) || eregi("\*union\*", $lid) || eregi("\+union\+", $lid) || eregi("\*", $lid))
{
echo "<br /><br /><div style=\"text-align: center;\"><big>This SQL injection is patched Now !!!</big></div><br /><br />";
redirect_header("index.php");
die();
}
else {

save and close the file and now it´s pached
try to exploit for verify :

http://localhost/bcoops/modules/mylinks/ratelink.php?lid=
-1%20UNION%20SELECT%20pass%20FROM%20bcoos_users%20LIMIT%201

###############################
patch adresses/ratefile.php
##############################

{
echo "<br /><br /><div style=\"text-align: center;\"><big>This SQL injection is patched Now !!!</big></div><br /><br />";
redirect_header("index.php");
die();
}
else {

save and close the file and now it´s pached
try to exploit for verify :

http://localhost/bcoops/modules/adresses/ratefile.php?
lid=-1%20UNION%20SELECT%20pass%20FROM%20bcoos_users%20LIMIT%201

###############################
patch mysections/ratefile.php
##############################

open ratefile.php and arround line 77 you have a else like } else {

put the code just before the else condition like :

}
if (eregi("%20union%20", $lid) ||eregi(" union ", $lid) || eregi("\*union\*", $lid) || eregi("\+union\+", $lid) || eregi("\*", $lid))
{
echo "<br /><br /><div style=\"text-align: center;\"><big>This SQL injection is patched Now !!!</big></div><br /><br />";
redirect_header("index.php");
die();
}
else {

save and close the file and now it´s pached
try to exploit for verify :

http://localhost/bcoops/modules/mysections/ratefile.php?
lid=-1%20UNION%20SELECT%20pass%20FROM%20bcoos_users%20LIMIT%201

############################
patch banners/click.php
############################

open click.php and arround line 5 you have $bid = $_GET['bid'];

put the code just after the this line :

if (eregi("%20union%20", $bid) ||eregi(" union ", $bid) || eregi("\*union\*", $bid) || eregi("\+union\+", $bid) || eregi("\*", $bid))
{
echo "<br /><br /><div style=\"text-align: center;\"><big>This SQL injection is patched Now !!!</big></div><br /><br />";
redirect_header("index.php");
die();
}

save and close the file and now it´s pached
try to exploit for verify :

http://localhost/bcoops/modules/banners/click.php?
bid=-1%20UNION%20SELECT%20pass%20FROM%20bcoos_users%20LIMIT%201

###########################
patch arcade/index.php
############################


open index.php and arround line 15 you have a switch($act)


put the code just before the switch


if (eregi("%20union%20", $gid) ||eregi(" union ", $gid) ||
eregi("\*union\*", $gid) || eregi("\+union\+", $gid) || eregi("\*",
$gid))
{
echo "<br /><br /><div style=\"text-align: center;\"><big>This SQL injection is patched Now !!!</big></div><br /><br />";
redirect_header("index.php");
die();
}

you can patch all of the rate files with the same code, because
for rating the code and funcions are similars in diferent modules.
