Alert meAnalysisAIv1 – Mar 12, 2026
Command injection in Tenda HG10 firmware's login interface allows unauthenticated remote attackers to execute arbitrary commands by manipulating the Host parameter in the checkUserFromLanOrWan function. Public exploit code exists for this vulnerability, and no patch is currently available. The attack requires no user interaction and can fully compromise affected devices through remote code execution.

Executive ViewAI
A HIGH severity authentication bypass vulnerability exists in Tenda HG10 routers that could allow attackers to gain unauthorized administrative access to network infrastructure. Organizations using this device model face immediate risk of network compromise, data theft, and service disruption, with no vendor patch currently available.
Disable remote WAN access to the login interface; restrict LAN access to the admin interface via firewall rules to trusted IPs only; implement network segmentation to isolate affected routers from sensitive systems; enable IP-based access control lists; consider deploying a WAF or reverse proxy in front of the device to monitor and block suspicious authentication attempts; monitor logs for brute force attacks on the /boaform/admin/formLogin endpoint; enforce strong password policies; consider disabling the device until replacement is feasible if it controls access to critical infrastructure.
