VAR-202209-1836
Vulnerability from variot - Updated: 2025-05-23 23:26Tenda AC18 router V15.03.05.19 contains a stack overflow vulnerability in the formSetQosBand->FUN_0007db78 function with the request /goform/SetNetControlList/. Shenzhen Tenda Technology Co.,Ltd. of AC18 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. The vulnerability is caused by the fact that the formSetQosBand function does not check the size of the input data. Attackers can exploit the vulnerability to cause remote code execution or denial of service
