VAR-202511-2330
Vulnerability from variot - Updated: 2025-12-20 23:44Shenzhen Tenda Technology Co.,Ltd. of ac21 A stack-based buffer overflow vulnerability exists in the firmware.Service operation interruption (DoS) It may be in a state. The Tenda AC21 is a dual-band gigabit wireless router from Tenda Technology, designed for high-speed home internet needs. It supports 802.11ac wave2 technology, with a dual-band concurrent speed of up to 2033Mbps, including 1733Mbps on the 5GHz band, meeting the demands of high-bandwidth applications such as 4K video and live streaming. This vulnerability stems from the fact that the urls parameter in the /goform/saveParentControlInfo file fails to properly validate the length of input data. Attackers can exploit this vulnerability to cause a denial-of-service attack

VAR-202509-1846
Vulnerability from variot - Updated: 2025-12-20 23:22A 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

VAR-202511-2233
Vulnerability from variot - Updated: 2025-11-28 23:23A flaw has been found in Tenda AC21 16.03.08.16. This affects an unknown part of the file /goform/SetIpMacBind. Executing manipulation of the argument list can lead to stack-based buffer overflow. The attack can be executed remotely. The exploit has been published and may be used. Shenzhen Tenda Technology Co.,Ltd. of ac21 The firmware contains a buffer error vulnerability and a stack-based buffer overflow vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. The Tenda AC21 is a dual-band gigabit wireless router from Tenda Technology, designed for high-speed home internet needs. It supports 802.11ac wave2 technology, with a dual-band concurrent speed of up to 2033Mbps, including 1733Mbps on the 5GHz band, meeting the demands of high-bandwidth applications such as 4K video and live streaming. This vulnerability stems from the /goform/SetIpMacBind file's parameter list failing to properly validate the length of input data. Attackers could exploit this vulnerability to execute arbitrary code or cause a denial-of-service attack

VAR-202511-2296
Vulnerability from variot - Updated: 2025-11-28 23:23Tenda AC21 V16.03.08.16 is vulnerable to Buffer Overflow in: /goform/SetVirtualServerCfg via the list parameter. Shenzhen Tenda Technology Co.,Ltd. of ac21 A stack-based buffer overflow vulnerability exists in the firmware.Service operation interruption (DoS) It may be in a state. The Tenda AC21 is a dual-band gigabit wireless router from Tenda Technology, designed for high-speed home internet needs. It supports 802.11ac wave2 technology, with a dual-band concurrent speed of up to 2033Mbps, including 1733Mbps on the 5GHz band, meeting the demands of high-bandwidth applications such as 4K video and live streaming. This vulnerability stems from the fact that the list parameter in /goform/SetVirtualServerCfg fails to properly validate the length of input data. Attackers can exploit this vulnerability to cause a denial-of-service attack

VAR-202511-0056
Vulnerability from variot - Updated: 2025-11-19 23:27A vulnerability was identified in Tenda AC21 16.03.08.16. This vulnerability affects the function formSetPPTPServer of the file /goform/SetPptpServerCfg. The manipulation of the argument startIp leads to buffer overflow. Remote exploitation of the attack is possible. The exploit is publicly available and might be used. An attacker could exploit this vulnerability to remotely manipulate the parameter, triggering a buffer overflow that could then execute arbitrary code or cause system crashes
