Quick assessment

Affected
Unknown OTP Login & Register Woocommerce
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.

在版本 2.7.3 之前，WooCommerce WordPress 插件"OTP Login & Register"未能对一次性密码（OTP）验证尝试次数进行有效限制。由于尝试次数限制是基于客户端自行提供且可自由更改的数值进行跟踪的，未认证的攻击者可借此绕过限制，通过暴力破解短数字登录代码，在无需密码的情况下接管用户账户。

Vulnerability Title
OTP Login & Register Woocommerce < 2.7.3 - Unauthenticated Account Takeover via OTP Brute Force
Source: CVE Program / CVE List V5
Vulnerability Description
The OTP Login & Register Woocommerce WordPress plugin before 2.7.3 does not adequately limit one-time-password verification attempts, because the attempt limit is tracked against a value the client itself supplies and can change freely, allowing an unauthenticated attacker to bypass the limit and brute-force the short numeric login code to take over an account without its password.
