VAR-202510-2210

Vulnerability from variot - Updated: 2025-11-19 23:11

A security flaw has been discovered in Tenda O3 1.0.0.10(2478). Affected by this issue is the function SetValue/GetValue of the file /goform/setDmzInfo. The manipulation of the argument dmzIP results in stack-based buffer overflow. It is possible to launch the attack remotely. The exploit has been released to the public and may be exploited. The Tenda O3 is an outdoor wireless bridge from Tenda, a Chinese company.

Tenda O3 version 1.0.0.10 contains a buffer overflow vulnerability. This vulnerability stems from the fact that the dmzIP parameter in the SetValue/GetValue function of the file /goform/setDmzInfo 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
