    "title": "Administrator Password Reset Through the Verification-Code Interface in TP-Link RE305",
    "summary": "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.",
