DreamAccount Include File Bug in 'auth.cookie.inc.php' Lets Remote Users Execute Arbitrary Code
SecurityTracker Alert ID:  1016272
SecurityTracker URL:  http://securitytracker.com/id/1016272
CVE Reference:   CVE-2006-2881   (Links to External Site)
Date:  Jun 13 2006
Impact:   Execution of arbitrary code via network, User access via network

Version(s): 3.1 and prior versions
Description:   David 'Aesthetico' Vieira-Kurz of MajorSecurity discovered a vulnerability in DreamAccount. A remote user can include and execute arbitrary code on the target system.

The 'auth.cookie.inc.php' script does not properly validate user-supplied input in the 'da_path' parameter. If register_globals is enabled, a remote user can supply a specially crafted URL to cause the target system to include and execute arbitrary PHP code from a remote location. The PHP code, including operating system commands, will run with the privileges of the target web service.

The 'auth.header.inc.php' and 'auth.sessions.inc.php' scripts are also affected.

The original advisory is available at:

Solution:   No solution was available at the time of this entry.

Cause:   Input validation error, State error
Underlying OS:  Linux (Any), UNIX (Any), Windows (Any)

Original Advisory:
----------------------------
http://www.majorsecurity.de/advisory/major_rls8.txt

Affected Products:
----------------------------

DreamAccount 3.1 and prior

Description:
----------------------------

DreamAccount is a membership and subscription software application that is both simple to use and install, 
while remaining affordable enough for even the smallest startup.

Requirements:
----------------------------

register_globals = On

Vulnerability:
----------------------------

Input passed to the "da_path" parameter in "auth.cookie.inc.php" is not
properly verified, before it is used to include files.
This can be exploited to execute arbitrary code by including files from external resources.

Solution:
----------------------------

I think you can fix this bug by replacing the following vulnerable code in the 
"auth.cookie.inc.php" with my one. It should fix the vulnerabilty and solve this
problem.

Vulnerable one:   "require($da_path . "setup.php");"
MajorSecurity fix: "require("setup.php");"

Set "register_globals" to "Off".

Exploitation:
----------------------------
