CVE-2021-44971

Estado: ModificadaCrítica (9.8)—

Multiple Tenda devices are affected by authentication bypass, such as AC15V1.0 Firmware V15.03.05.20_multi?AC5V1.0 Firmware V15.03.06.48_multi and so on. an attacker can obtain sensitive information, and even combine it with authenticated command injection to implement RCE.
