VAR-202510-2084

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

A vulnerability was determined in Tenda O3 1.0.0.10(2478). Affected is the function SetValue/GetValue of the file /goform/setDhcpConfig. Executing manipulation of the argument dhcpEn can lead to stack-based buffer overflow. The attack may be performed from remote. The exploit has been publicly disclosed and may be utilized. The Tenda O3 is an outdoor wireless bridge from Tenda, a Chinese company. This vulnerability stems from the fact that the dhcpEn parameter in the SetValue/GetValue function of the file /goform/setDhcpConfig 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
