  Gridscan.com Security-risk


 <http://www.tobiaspreis.de/> Gridscan.com provides web masters with a
search engine by only asking them to include a single line inside their
existing PHP scripts. This however, poses a serious security risk, since
the code provided by this single ("require" statement) line can include
any kind of code, even command execution code.


The single row that the administrator needs to add is this:
 <? require("http://www.tobiaspreis.de/grid.php"); ?>

This line would allow the administrator of tobiaspreis.de to easily modify
his grid.php to do almost anything on your webserver with full user rights
of your PHP-scripts. Further this server (tobiaspreis.de) is a very good
target for hackers, because by gaining access to this server, an attacker
can compromise a large number of websites.
