Summary

TP-Link RE305 v3 before 1.1.8 Build 20260921 Rel. 42853 has an authentication flaw in its password-recovery functionality. The verification-code interface generates administrator password-reset codes with a predictable process (CWE-338) and has no effective attempt counter or lockout. An unauthenticated attacker on the same local network can obtain or brute-force a code and reset the administrator password, then access privileged device-management functions.

Description from the CNA

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.
