pretix

Exploitation

No confirmed in-the-wild exploitation; assess based on exposure

Recommended action

Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

我们的一些 API 端点允许使用自增的内部 ID 来创建指向礼品卡的订单支付。由于该 ID 未经校验，攻击者可以创建指向其他组织者的礼品卡的支付记录，从而获取其密钥。虽然在此情况下礼品卡不会被扣款，但随后对该支付发起退款，即可增加该礼品卡的余额。

Vulnerability Title

Giftcard enumeration

Source: CVE Program / CVE List V5

Vulnerability Description

Some of our API endpoints allowed to create order payments referencing a gift card by using the auto-incremented internal ID. This ID was not checked and allowed creating payments that reference gift cards from different organizers and thereby obtaining their secret. The gift card is not charged in this case, but by then triggering a refund on the payment, one can increase the value of the gift card.
