TITLE

Tenda O3 formAdvSetLanip function buffer overflow vulnerability

Trust: 0.6

sources: CNVD: CNVD-2025-27237

DESCRIPTION

A vulnerability was identified in Tenda O3 1.0.0.10(2478). Affected by this vulnerability is the function SetValue/GetValue of the file /goform/AdvSetLanip. The manipulation of the argument lanIp leads to stack-based buffer overflow. It is possible to initiate the attack remotely. The exploit is publicly available and might be used. The Tenda O3 is an outdoor wireless bridge from Tenda, a Chinese company. This vulnerability stems from the fact that the `lanIp` parameter in the `SetValue`/`GetValue` function of the file `/goform/AdvSetLanip` fails to properly validate the length of the input data. Attackers could exploit this vulnerability to execute arbitrary code on the system or cause a denial-of-service attack
