Quick assessment

Affected
TP-Link Systems Inc. RE305 v3
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.

TP-Link RE305 V3 的密码恢复功能中存在一个身份验证漏洞。其验证码接口允许同一本地网络中的未认证攻击者触发管理员密码重置验证码的生成。由于该接口缺乏有效的尝试次数计数器或锁定机制，且验证码生成过程具有可预测性，攻击者可能获取或暴力破解该验证码，从而重置管理员密码。 成功利用此漏洞后，本地网络中的未认证攻击者即可重置管理员密码，进而访问设备的特权管理功能。

Vulnerability Title
Administrator Password Reset Through the Verification-Code Interface in TP-Link RE305
Source: CVE Program / CVE List V5
Vulnerability Description
An authentication flaw exists in the password-recovery functionality of TP-Link RE305 V3. The verification-code interface allows an unauthenticated attacker on the same local network to trigger generation of an administrator password-reset verification code. Because the interface lacks an effective attempt counter or lockout mechanism and uses a predictable verification-code generation process, an attacker may obtain or brute-force the code and reset the administrator password.  Successful exploitation may allow an unauthenticated attacker on the local network to reset the administrator password and subsequently access privileged device-management functions.
