Technical Description
TP-Link Deco M5 v1 uses a weak password hashing mechanism to store user credentials. An attacker who obtains the password hash through system compromise or privileged access could perform brute-force or dictionary attacks.
Successful exploitation may result in disclosure of authentication credentials, enabling unauthorized access to device management functions, depending on the privileges associated with the recovered password. The primary security impact is loss of confidentiality.
Remediation
Check the references section for vendor advisories and patches from tp-link. Update deco_m5_firmware to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
