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

PopnupBlog contains a flaw that allows a remote
cross site scripting attack.This flaw exists because
the application does not validate 'param' , 'cat_id' and
'view' variables upon submission to 'index.php' script.
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.

##########
versions
##########

PopnupBlog 3.20 code name: Denali

Prior versions can be vulnerables too.
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
############

No solution at this time !!!

But you can edit the source code and ix it like:

for fix 'param' open index.php and arround line 37 we have

[code]
$params = PopnupBlogUtils::getDateFromHttpParams();
$start = PopnupBlogUtils::getStartFromHttpParams();
$view = $BlogCNF['default_view'];
$select_uid = isset($_GET['uid']) ? intval($_GET['uid']) : 0;
[/code]

add a line to force 'param' to return a integer:

[code]
$_GET['param'] = intval($_GET['param']);
$params = PopnupBlogUtils::getDateFromHttpParams();
$start = PopnupBlogUtils::getStartFromHttpParams();
$view = $BlogCNF['default_view'];
$select_uid = isset($_GET['uid']) ? intval($_GET['uid']) : 0;
[/code]

for fix 'cat_id' and 'view' open index.php and arround line 129 :

[code]
$xoopsTpl->assign('popimg',PopnupBlogUtils::mail_popimg()); // get email
$cat_id=0;
if (isset($_GET['cat_id'])) $cat_id = $_GET['cat_id'];
if (isset($_POST['cat_id'])) $cat_id = $_POST['cat_id'];
$xoopsTpl->assign('popnupblog', PopnupBlogUtils::get_blog_list($start,$cat_id,$select_uid));
if (isset($_GET['view'])) $view = $_GET['view'];
if (isset($_POST['view'])) $view = $_POST['view'];
[/code]

add intval to force variables to return an integer like:

[code]
$xoopsTpl->assign('popimg',PopnupBlogUtils::mail_popimg()); // get email
$cat_id=0;
if (isset($_GET['cat_id'])) $cat_id = intval($_GET['cat_id']);
if (isset($_POST['cat_id'])) $cat_id = intval($_POST['cat_id']);
$xoopsTpl->assign('popnupblog', PopnupBlogUtils::get_blog_list($start,$cat_id,$select_uid));
if (isset($_GET['view'])) $view = intval($_GET['view']);
if (isset($_POST['view'])) $view = intval($_POST['view']);
[/code]

if the sito don´t have instaled 848 Core HotFix Pack 3
(0848bC1_HFP3.zip) this system have one XSS hole in query
variable upon submision to index.php script wen L param is
set to blogs.search:

For exploit this issue The attacker
need a Admin account.

http://localhost/phpizabi/index.php?L=
admin.templates.edittemplate&id=../../../boot.ini

we can too 'view' the html source code generated by
a remote server like :

FIX XSS in RMSOFT donwload plus

fixing XSS issues in RMSOFT donwload plus


RMSOFT XSS Vulnerability
report:
http://lostmon.blogspot.com/2008/08/rmsoft-downloads-plus-two-scripts-two.html

###################
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]
