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

rConfig 8.0.0 至 8.2.13 版本之间存在一个认证绕过漏洞。该漏洞是由于在 文件中存在重复的 调用，导致在显式禁用 POST /register 路由后，该路由被重新启用。攻击者可以利用此漏洞以未认证身份自行注册账户，并获得完整的管理员权限。 攻击者可以注册一个新账户，该账户在注册完成后立即获得管理员级别的访问权限。这是因为注册控制器未为用户分配角色，而 字段默认值为“Admin”。由此，攻击者能够访问存储在系统中的设备凭据、用户数据，并可签发 API 令牌。

Vulnerability Title
rConfig 8.0.0 < 8.2.10 Unauthorized Admin Registration via web.php
Source: CVE Program / CVE List V5
Vulnerability Description
rConfig 8.0.0 before 8.2.13 contains an authentication bypass vulnerability that allows unauthenticated attackers to self-register accounts with full Administrator privileges due to a duplicate bare Auth::routes() call in routes/web.php that re-enables the POST /register route after it was explicitly disabled. Attackers can register a new account that is immediately authenticated with Admin-level access because the registration controller does not assign a role and the users.role column defaults to Admin, enabling access to stored device credentials, user data, and API token issuance.
