Name of the Vulnerable Software and Affected Versions Tenda AC10U version 15.03.06.49

Description The issue is related to a stack-based buffer overflow in the Tenda AC10U router's firmware, specifically affecting the function formSetFirewallCfg (/goform/SetFirewallCfg) and formSetDeviceName of the file /goform/SetOnlineDevName. The manipulation of the mac argument leads to this overflow. It is possible to launch the attack remotely, which may allow an attacker to impact the confidentiality, integrity, and availability of protected information.

Recommendations For Tenda AC10U version 15.03.06.49, as a temporary workaround, consider blocking access to the admin interface until a patch is available. Restrict access to the vulnerable function formSetDeviceName to minimize the risk of exploitation. Avoid using the mac parameter in the affected API endpoint /goform/SetOnlineDevName until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
