CVE-2026-19791: Stack-based Buffer Overflow in Tenda G0
A weakness has been identified in Tenda G0 up to 20260625. The affected element is the function addStaticRoute of the file /goform/module of the component httpd web management interface. Executing a manipulation of the argument staticRouteNet can lead to stack-based buffer overflow. The attack may be performed from remote. The exploit has been made available to the public and could be used for attacks.
AI Analysis
Technical Summary
This vulnerability exists in Tenda G0 devices up to version 20260625 in the addStaticRoute function of the /goform/module HTTP web management interface component. By sending a specially crafted request manipulating the staticRouteNet parameter, an attacker can cause a stack-based buffer overflow. This flaw can be exploited remotely without user interaction and requires low attack complexity and privileges. The vulnerability has a high impact on confidentiality, integrity, and availability. Public exploit code is available, but no official patch or fix has been documented yet.
Potential Impact
Successful exploitation of this vulnerability could allow a remote attacker to execute arbitrary code on the affected device, potentially leading to full compromise of the device's functionality and data. The vulnerability impacts confidentiality, integrity, and availability of the device. Given the remote attack vector and public exploit availability, the risk of exploitation is significant.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the device's web management interface from untrusted networks to reduce exposure. Monitor vendor communications for updates regarding patches or mitigations.
