VAR-202510-2086
Vulnerability from variot - Updated: 2025-11-19 23:31Tenda AC6 V2.0 15.03.06.50 was discovered to contain a buffer overflow in the speed_dir parameter in the SetSpeedWan function. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted input. The Tenda AC6 is a wireless router manufactured by Tenda, a Chinese company. This vulnerability stems from the fact that the speed_dir parameter in the SetSpeedWan function fails to properly validate the length of the input data

VAR-202509-3067
Vulnerability from variot - Updated: 2025-11-19 23:30Tenda AC6 router firmware 15.03.05.19 contains a command injection vulnerability in the formSetIptv function, which processes requests to the /goform/SetIPTVCfg web interface. When handling the list and vlanId parameters, the sub_ADBC0 helper function concatenates these user-supplied values into nvram set system commands using doSystemCmd, without validating or sanitizing special characters (e.g., ;, ", #). An unauthenticated or authenticated attacker can exploit this by submitting a crafted POST request, leading to arbitrary system command execution on the affected device. The Tenda AC6 is a dual-band wireless router from Tenda, supporting both 2.4GHz and 5GHz bands and achieving a maximum transfer rate of 1167Mbps. Detailed vulnerability details are currently unavailable

VAR-202509-3635
Vulnerability from variot - Updated: 2025-11-19 23:28An issue was discovered in Tenda AC6 US_AC6V1.0BR_V15.03.05.16_multi_TD01 allowing attackers to cause a denial of service via the funcname, funcpara1, funcpara2 parameters to the formSetCfm function (uri path: SetCfm). Shenzhen Tenda Technology Co.,Ltd. of AC6 There is an input validation vulnerability in firmware.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. The Tenda AC6 is a dual-band wireless router from Tenda, supporting both 2.4GHz and 5GHz bands and achieving a maximum transmission rate of 1167Mbps.
The Tenda AC6 suffers from an improper input validation vulnerability caused by improper handling of the funcname, funcpara1, and funcpara2 parameters in the formSetCfm function. Detailed vulnerability details are currently unavailable

VAR-202510-2250
Vulnerability from variot - Updated: 2025-11-19 23:27Multiple buffer overflows in the SetClientState function of Tenda AC6 v.15.03.06.50 allows attackers to cause a Denial of Service (DoS) via injecting a crafted payload into the limitSpeed, deviceId, and limitSpeedUp parameters. The Tenda AC6 is a wireless router manufactured by Tenda, a Chinese company.
Version 15.03.06.50 of the Tenda AC6 contains a buffer overflow vulnerability. This vulnerability stems from the SetClientState function's failure 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-202510-2306
Vulnerability from variot - Updated: 2025-11-19 23:27A vulnerability has been found in Tenda AC6 15.03.06.50. This issue affects some unknown processing of the file /goform/WifiGuestSet of the component HTTP Request Handler. Such manipulation of the argument shareSpeed leads to stack-based buffer overflow. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. The Tenda AC6 is a wireless router manufactured by Tenda, a Chinese company. This vulnerability stems from the fact that the parameter shareSpeed in the file /goform/WifiGuestSet fails to properly validate the length of the input data. Attackers could exploit this vulnerability to execute arbitrary code on the system or cause a denial-of-service attack

"data": "A vulnerability has been found in Tenda AC6 15.03.06.50. This issue affects some unknown processing of the file /goform/WifiGuestSet of the component HTTP Request Handler. Such manipulation of the argument shareSpeed leads to stack-based buffer overflow. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. The Tenda AC6 is a wireless router manufactured by Tenda, a Chinese company. This vulnerability stems from the fact that the parameter `shareSpeed` in the file `/goform/WifiGuestSet` fails to properly validate the length of the input data. Attackers could exploit this vulnerability to execute arbitrary code on the system or cause a denial-of-service attack",

VAR-202510-2215
Vulnerability from variot - Updated: 2025-11-19 23:17Tenda AC6 V2.0 15.03.06.50 was discovered to contain a stack overflow in the ssid parameter in the fast_setting_wifi_set function. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted input. The Tenda AC6 is a dual-band wireless router from Tenda, designed specifically for home users with 100Mbps fiber optic connections. This vulnerability stems from the fact that the SSID parameter in the fast_setting_wifi_set function fails to properly validate the length of the input data

VAR-202510-2278
Vulnerability from variot - Updated: 2025-11-19 23:17Multiple buffer overflows in the AdvSetMacMtuWan function of Tenda AC6 v.15.03.06.50 allows attackers to cause a Denial of Service (DoS) via injecting a crafted payload into the wanMTU, wanSpeed, cloneType, mac, serviceName, serverName, wanMTU2, wanSpeed2, cloneType2, mac2, serviceName2, and serverName2 parameters. The Tenda AC6 is a wireless router manufactured by Tenda, a Chinese company.
Version 15.03.06.50 of the Tenda AC6 contains a buffer overflow vulnerability. This vulnerability stems from the AdvSetMacMtuWan function 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-202308-3530
Vulnerability from variot - Updated: 2025-09-18 23:18Tenda AC6 US_AC6V1.0BR_V15.03.05.16_multi_TD01.bin is vulnerable to Buffer Overflow via function "add_white_node,". The Tenda AC6 is a dual-band wireless router from Tenda. It supports both 2.4GHz and 5GHz bands, boasts a maximum transmission rate of 1167Mbps, and features dual-band integration.
The Tenda AC6 suffers from a buffer overflow vulnerability caused by the add_white_node function's failure to properly validate the length of input data. An attacker could exploit this vulnerability to execute arbitrary code or cause a denial of service

VAR-202308-3556
Vulnerability from variot - Updated: 2025-09-18 23:12Tenda AC6 US_AC6V1.0BR_V15.03.05.16_multi_TD01.bin is vulnerable to Buffer Overflow via function "fromGetWirelessRepeat.". The Tenda AC6 is a dual-band wireless router from Tenda. It supports both 2.4GHz and 5GHz bands, boasts a maximum transmission rate of 1167Mbps, and features dual-band integration.
The Tenda AC6 suffers from a buffer overflow vulnerability caused by the fromGetWirelessRepeat function's failure to properly validate the length of input data. An attacker could exploit this vulnerability to execute arbitrary code or cause a denial of service

The Tenda AC6 is a dual-band wireless router from Tenda. It supports both 2.4GHz and 5GHz bands, boasts a maximum transmission rate of 1167Mbps, and features dual-band integration.
The Tenda AC6 suffers from a buffer overflow vulnerability caused by the R7WebsSecurityHandler function's failure to properly validate the length of input data. An attacker could exploit this vulnerability to execute arbitrary code or cause a denial of service
