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
