What to do
AI-suggested
European organizations should immediately inventory their network devices to identify any Tenda AC10 routers running the vulnerable firmware version US_AC10V4.0si_V16.03.10.13_cn. Until an official patch is released, organizations should restrict remote access to router management interfaces by implementing network segmentation and firewall rules that limit access to trusted IP addresses only. Disabling remote management features and UPnP on these devices can reduce exposure. Monitoring network traffic for unusual patterns or signs of exploitation attempts is advised. Organizations should also subscribe to vendor advisories and CVE databases for updates on patches or workarounds. Where possible, replacing vulnerable devices with alternative models that receive timely security updates is recommended. Employing network intrusion detection systems (NIDS) with signatures for stack overflow attempts targeting Tenda routers can provide early warning. Finally, educating users about the risks and encouraging prompt firmware updates when available will help mitigate the threat.
Description
Tenda AC10 version US_AC10V4.0si_V16.03.10.13_cn was discovered to contain a stack overflow via the firewallEn parameter in the function SetFirewallCfg.
