TITLE

Tenda O3 buffer overflow vulnerability (CNVD-2025-26877)

Trust: 0.6

sources: CNVD: CNVD-2025-26877

DESCRIPTION

A security vulnerability has been detected in Tenda O3 1.0.0.10(2478). This vulnerability affects the function SetValue/GetValue of the file /goform/setVlanConfig. Such manipulation of the argument lan leads to stack-based buffer overflow. The attack can be launched remotely. The exploit has been disclosed publicly and may be used. The Tenda O3 is an outdoor wireless bridge manufactured by Tenda, a Chinese company. This vulnerability stems from the fact that the `lan` parameter in the file `/goform/setVlanConfig` fails to properly validate the length of the input data. An attacker could exploit this vulnerability to cause a stack overflow
