###################
FIX $key variable
###################

open modules/rmdp/include/rmdp_functions.php

arround line 314 found function rmdp_make_searchnav()

found this code:
#####################
[code]

function rmdp_make_searchnav(){
global $xoopsDB, $xoopsTpl, $xoopsModule;

$xoopsTpl->assign('lng_allweb', sprintf(_RMDP_ALL_WEB, $xoopsModule->getVar('name')));
$xoopsTpl->assign('lng_search_button',_RMDP_SEARCH_BUTTON);
$key = isset($_POST['key']) ? $_POST['key'] : (isset($_GET['key']) ?($_GET['key'] : '');

$xoopsTpl->assign('key', $key);
[/code]

the variable $key is vulnerable in GET & POST.
Now add htmlspecialchars() function:
change for this other:

[code]
function rmdp_make_searchnav(){
global $xoopsDB, $xoopsTpl, $xoopsModule;

$xoopsTpl->assign('lng_allweb', sprintf(_RMDP_ALL_WEB, $xoopsModule->getVar('name')));
$xoopsTpl->assign('lng_search_button',_RMDP_SEARCH_BUTTON);
$key = isset($_POST['key']) ? htmlspecialchars($_POST['key']) : (isset($_GET['key']) ? htmlspecialchars($_GET['key']) : '');

$xoopsTpl->assign('key', $key);
[/code]

now variable is clean in functions, but we need to sanitize again in search.php...

open modules/rmdp/search.php

arround line 37 we found two request to $key variable:
[code]
$rmdp_location = 'search';
include('header.php');
$key = $_GET['key'];
if ($key==''){ $key=$_POST['key']; }
$cat = isset($_GET['cat']) ? $_GET['cat'] : (isset($_POST['cat']) ? $_POST['cat'] : 0);
[/code]

need a cleaning :S use again htmlspecialchars() y GET & POST
change by this other:

[code]$rmdp_location = 'search';
include('header.php');
$key = htmlspecialchars($_GET['key']);
if ($key==''){ $key=htmlspecialchars($_POST['key']); }
$cat = isset($_GET['cat']) ? $_GET['cat'] : (isset($_POST['cat']) ? $_POST['cat'] : 0);
[/code]

$cat aparently is sanitized , but if is a numeric value allways i ithink in use intval() like :

[code]
$cat = isset($_GET['cat']) ? intval($_GET['cat']) : (isset($_POST['cat']) ? intval($_POST['cat']) : 0);
[/code]

#############################
fix $id variable in down.php
#############################

open modules/down.php and arround line 38 found this code line:

[code]$id = $_GET['id'];[/code]

it´s a numerical variable value always and them...
yo can change by this other to sanitizing :

[code]$id = intval($_GET['id']);[/code]

Yogurt Social Network is a social network php/Mysql script
module for multiple CMS Systems like Xoops,e-xoops,bcoos and
impressCMS and probably in all CMS based in Xoops code.

Yogurt Social Network contains a flaw that allows a remote
cross site scripting attack.This flaw exists because
the application does not validate 'uid' variable upon
submission to Multiple scripts script in yogurt 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.
