CVE-2026-19791

Name of the Vulnerable Software and Affected Versions Tenda G0 versions prior to 20260625

Description A stack-based buffer overflow exists in the httpd web management interface. The issue occurs within the addStaticRoute() function located in the /goform/module file. A remote attacker can trigger this by manipulating the staticRouteNet argument. A stack-based buffer overflow is a condition where a program writes more data to a buffer located on the stack than the buffer is allocated to hold, potentially leading to crashes or arbitrary code execution.

Recommendations Update Tenda G0 to a version released after 20260625. As a temporary mitigation, restrict access to the addStaticRoute() function within the httpd web management interface.
