DESCRIPTION:
A vulnerability has been reported in osCommerce, which can be
exploited by malicious users to bypass certain security
restrictions.

Input passed via the merchant's PayPal email address is not properly
verified before being used to initiate a PayPal transaction and can
be exploited to modify a merchant's email address and subsequently
the payee of a PayPal transaction.

Successful exploitation requires the PayPal Website Payments Standard
module to be enabled, a PayPal transaction utilising the module, and
the "Encrypted Web Payments" module configuration to be disabled
(disabled by default).

The vulnerability is reported in osCommerce version 2.3.1 running
with PayPal Website Payments Standard module version 1.0.

SOLUTION:
No official solution is currently available. Reportedly, an updated
version 2.3.4 with PayPal Website Payments Standard module version
1.1 will address this vulnerability.
