VAR-202506-0500

Vulnerability from variot - Updated: 2025-07-17 23:45

A vulnerability, which was classified as critical, has been found in Tenda AC9 15.03.02.13. Affected by this issue is the function fromadvsetlanip of the file /goform/AdvSetLanip of the component POST Request Handler. The manipulation of the argument lanMask leads to buffer overflow. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. Shenzhen Tenda Technology Co.,Ltd. of AC9 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. The vulnerability is caused by the parameter lanMask in the file /goform/AdvSetLanip 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
