VAR-202510-2331

Vulnerability from variot - Updated: 2025-11-19 23:24

Totolink A7000R v9.1.0u.6115_B20201022 was discovered to contain a stack overflow via the ssid5g parameter in the sub_421CF0 function. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted request. The TOTOLINK A7000R is a wireless router launched by TOTOLINK Electronics Co., Ltd. in China. It supports WiFi 7 technology and is suitable for home or small business network environments. This vulnerability stems from the fact that the ssid5g parameter in the sub_421CF0 function fails to properly validate the length of the input data

VAR-202510-2144

Vulnerability from variot - Updated: 2025-11-19 23:22

Totolink A7000R v9.1.0u.6115_B20201022 was discovered to contain a stack overflow via the ssid5g parameter in the urldecode function. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted request. The TOTOLINK A7000R is a wireless router launched by TOTOLINK Electronics Co., Ltd. in China. It supports WiFi 7 technology and is suitable for home or small business network environments. This vulnerability stems from the fact that the ssid5g parameter in the urldecode function fails to properly validate the length of the input data

VAR-202510-2190

Vulnerability from variot - Updated: 2025-11-19 23:20

Totolink A7000R v9.1.0u.6115_B20201022 was discovered to contain a stack overflow via the ssid5g parameter in the sub_4222E0 function. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted request. The TOTOLINK A7000R is a wireless router launched by TOTOLINK Electronics Co., Ltd. in China. It supports WiFi 7 technology and is suitable for home or small business network environments. This vulnerability stems from the fact that the ssid5g parameter in the sub_4222E0 function fails to properly validate the length of the input data. An attacker could exploit this vulnerability to cause a denial-of-service attack

VAR-202510-2332

Vulnerability from variot - Updated: 2025-11-19 23:14

Totolink A7000R v9.1.0u.6115_B20201022 was discovered to contain a stack overflow via the wifiOff parameter in the sub_421A04 function. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted request. The TOTOLINK A7000R is a wireless router launched by TOTOLINK Electronics Co., Ltd. in China. It supports WiFi 7 technology and is suitable for home or small business network environments. This vulnerability stems from the fact that the wifiOff parameter in the sub_421A04 function fails to properly validate the length of the input data

Vulnerability from variot - Updated: 2025-06-21 23:30

A vulnerability, which was classified as critical, has been found in TOTOLINK A7000R 9.1.0u.6268_B20220504. This issue affects the function loginauth of the file /cgi-bin/cstecgi.cgi. The manipulation of the argument password leads to buffer overflow. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. The associated identifier of this vulnerability is VDB-272783. NOTE: The vendor was contacted early about this disclosure but did not respond in any way. TOTOLINK of a7000r Firmware has a classic buffer overflow vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. TOTOLINK A7000R is a wireless router produced by China's TOTOLINK Electronics. The vulnerability is caused by the password parameter in the loginauth function of the /cgi-bin/cstecgi.cgi page failing to properly verify the length of the input data. Attackers can exploit this vulnerability to execute arbitrary code on the system or cause a denial of service

Vulnerability from variot - Updated: 2024-12-21 23:18

TOTOLINK X5000R V9.1.0u.6118_B20201102 and TOTOLINK A7000R V9.1.0u.6115_B20201022 was discovered to contain a stack overflow via the http_host parameter in the function loginAuth. TOTOLINK of X5000R firmware and a7000r An out-of-bounds write vulnerability exists in firmware.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. TOTOLINK X5000R is a router. TOTOLINK A7000R is a wireless router.

There is a buffer overflow vulnerability in TOTOLINK X5000R and A7000R. The vulnerability is caused by the http_host parameter in the loginAuth function failing to properly verify the length of the input data. Attackers can exploit this vulnerability to execute arbitrary code on the system or cause a denial of service

VAR-202407-2421

Vulnerability from variot - Updated: 2024-08-29 23:14

A vulnerability, which was classified as critical, was found in TOTOLINK A7000R 9.1.0u.6268_B20220504. Affected is the function setWizardCfg of the file /cgi-bin/cstecgi.cgi. The manipulation of the argument ssid leads to buffer overflow. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. The identifier of this vulnerability is VDB-272784. NOTE: The vendor was contacted early about this disclosure but did not respond in any way. TOTOLINK of a7000r Firmware has a classic buffer overflow vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. TOTOLINK A7000R is a wireless router produced by China's TOTOLINK Electronics.

There is a buffer overflow vulnerability in the TOTOLINK A7000R 9.1.0u.6268_B20220504 version. The vulnerability is caused by the ssid parameter in the setWizardCfg function of the /cgi-bin/cstecgi.cgi page failing to correctly verify the length of the input data. Remote attackers can exploit this vulnerability to execute arbitrary code on the system or cause a denial of service attack
