## Summary

The TP-Link RE305 V3 range extender's password-recovery feature is affected. An unauthenticated attacker on the same local network could reset the device's administrator password and then gain access to privileged management functions.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- TP-Link Systems Inc. RE305 v3: fixed in 1.1.8 Build 20260921 Rel. 42853

## 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.

## What to do

- Check your stack: if you ship or depend on TP-Link Systems Inc. RE305 v3, upgrade to a fixed version (1.1.8 Build 20260921 Rel. 42853) per the references below.
