Recommended action

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

在 webpanel_version 1.16 之前的 Control Web Panel (CWP) 中，循环接口（loopback API）的身份验证网关函数 access_token() 存在 SQL 注入漏洞。该函数以 root 用户身份连接 MySQL，并将攻击者可控制的值直接拼接到查询语句中。攻击者可通过 authorization_code 和 client_id 参数注入 SQL 代码，从而读取任意数据库内容、伪造身份验证结果，并绕过 API 的身份验证检查。

Vulnerability Title

Control Web Panel (CWP) < 1.16 SQL Injection via access_token() API

Source: CVE Program / CVE List V5

Vulnerability Description

Control Web Panel (CWP) before webpanel_version 1.16 contains a SQL injection vulnerability in the loopback API authentication gate access_token(), which connects to MySQL as root and interpolates attacker-controlled values directly into its query. Attackers can inject SQL through the authorization_code and client_id parameters to read arbitrary database contents and forge the authentication result, bypassing the API's authentication check.
