Alstrasoft Epay Pro Directory Traversal
------------------------------------------------------------------------

SUMMARY

<http://www.alstrasoft.com/epay.htm> EPay Pro is "the ultimate software
solution for those who wish to run their own Paypal, Stormpay, or e-gold
type of online business. Epay Pro comes with a ready out of the box
website with all the features you need to run your own payment gateway
system".

Alstrasoft Epay Pro has been found to be vulnerable to a directory
traversal vulnerability, allowing remote attackers to access sensitive
information on the vulnerable system.

DETAILS

Vulnerable Systems:
* Epay Pro versions 2.0 and prior

EPay's Pro vulnerability caused by an improper validation of user-supplied
input.

A remote attacker could embed in the index.php etc/passwd containing
embedded code in the payment or send parameter which, once the link is
clicked, would be executed to see passwords within the security context of
the hosting server. An attacker could use this vulnerability to see all
the victim's password authentication credentials.

Example:
http://targeturl/index.php?read=../../../../../../../../../../../../../../etc/passwd
