VAR-202509-1846

Vulnerability from variot - Updated: 2025-12-20 23:22

A vulnerability was identified in Tenda AC21 16.03.08.16. The affected element is the function sub_45BB10 of the file /goform/WifiExtraSet. The manipulation of the argument wpapsk_crypto leads to buffer overflow. It is possible to initiate the attack remotely. The exploit is publicly available and might be used. Shenzhen Tenda Technology Co.,Ltd. of ac21 The firmware contains a buffer error vulnerability and a classic buffer overflow vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. This vulnerability stems from the fact that the parameter wpapsk_crypto in the function sub_45BB10 within the file /goform/WifiExtraSet fails to properly validate the length of the input data. Attackers could exploit this vulnerability to execute arbitrary code or cause a denial-of-service attack
