# TP-Link RE305 V3: weak password-recovery codes let attackers reset admin password

The password-recovery interface on the TP-Link RE305 V3 range extender generates administrator reset codes predictably and has no effective attempt limit or lockout. An unauthenticated attacker on the same local network can guess or brute-force the code, reset the admin password, and then control device management.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the firmware version on the device admin page or in the app and compare it with the vendor advisory: unknown
- Confirm whether the device admin interface is reachable from networks other than your own LAN: unknown

## Fix

- Update RE305 V3 firmware to the version the TP-Link advisory names: unknown
- Until patched, change the admin password and restrict access to the device's management interface to trusted hosts.

## From the sources

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.
