VAR-202506-0835

Vulnerability from variot - Updated: 2025-06-26 19:34

A vulnerability, which was classified as critical, was found in Tenda FH1203 2.0.1.6. Affected is the function fromadvsetlanip of the file /goform/AdvSetLanip. The manipulation of the argument lanMask leads to buffer overflow. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. Shenzhen Tenda Technology Co.,Ltd. of fh1203 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 of the fromadvsetlanip function 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
