TITLE:
phpMyDesktop|arcade Local File Inclusion and Script Insertion

SECUNIA ADVISORY ID:
SA20373

VERIFY ADVISORY:
http://secunia.com/advisories/20373/

CRITICAL:
Highly critical

IMPACT:
Exposure of sensitive information, System access, Cross Site
Scripting

WHERE:
>From remote

SOFTWARE:
phpMyDesktop|arcade 1.x
http://secunia.com/product/10244/

DESCRIPTION:
darkgod has discovered two vulnerabilities in phpMyDesktop|arcade,
which can be exploited by malicious people to conduct script
insertion attacks, disclose sensitive information, and compromise a
vulnerable system.

1) Input passed to the "subsite" parameter in index.php isn't
properly verified, before it is used to include files. This can be
exploited to include arbitrary files from local resources.

Example:
http://[host]/index.php?todo=showsubsite&subsite=[file]%00

This can further be exploited to include arbitrary PHP code injected
into uploaded images.

Successful exploitation requires that "magic_quotes_gpc" is
disabled.

2) The problem is that it is possible to upload images with arbitrary
content to a location inside the web root when posting. This can be
exploited to execute arbitrary HTML and script code in a user's
browser session in context of an affected site.

Successful exploitation requires the malicious image is viewed
directly with the Microsoft Internet Explorer browser.

The vulnerabilities have been confirmed in version 1.0. Other
versions may also be affected.

SOLUTION:
Edit the source code to ensure that input is properly verified.

PROVIDED AND/OR DISCOVERED BY:
