Quick assessment

Affected
balbooa.com Balbooa Forms extension for Joomla
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.

Joomla 扩展 – balbooa.com – Balbooa Forms（版本低于 2.4.3.2）存在预认证支付金额篡改漏洞。 stripeCharges 和 payAuthorize 两个接口直接从客户端控制的请求参数中获取支付总额，并未经过基于表单配置产品价格的重新计算，便将其转发至支付网关。此外，这两个接口均未实施身份验证或跨站请求伪造（CSRF）检查。因此，未经认证的攻击者可以以任意金额（例如 0.01 美元）购买任何标价商品，并且还可以伪造行项目、数量以及运费信息。

Source: CVE Program / CVE List V5
Vulnerability Description
Joomla Extension - balbooa.com - Pre-auth Payment Amount Tampering in Balbooa Forms < 2.4.3.2 - The stripeCharges and payAuthorize endpoints accept the charge total from a client-controlled request parameter and forward it to the payment gateway without recomputing it from the form's configured product prices. Neither endpoint enforces authentication or CSRF checks. An unauthenticated attacker can purchase any priced item for an arbitrary amount (e.g., $0.01), and can additionally forge line items, quantities, and shipping.
