An issue was discovered on Tenda RX2 Pro 16.03.30.14 devices. Improper network isolation between the guest Wi-Fi network and other network interfaces on the router allows an attacker (who is authenticated to the guest Wi-Fi) to access resources on the router and/or resources and devices on other networks hosted by the router by configuring a static IP address (within the non-guest subnet) on their host.

Cleartext transmission of sensitive information in the web management portal of the Tenda RX2 Pro 16.03.30.14 may allow an unauthenticated attacker to authenticate to the web management portal by collecting credentials from observed/collected traffic. It implements encryption, but not until after the user has transmitted the hash of their password in cleartext. The hash can be replayed to authenticate.

Cleartext transmission of sensitive information in the web management portal of the Tenda RX2 Pro 16.03.30.14 allows an attacker to decrypt traffic between the client and server by collecting the symmetric AES key from collected and/or observed traffic. The AES key in sent in cleartext in response to successful authentication. The IV is always EU5H62G9ICGRNI43.

Initialization vector (IV) reuse in the web management portal of the Tenda RX2 Pro 16.03.30.14 may allow an attacker to discern information about or more easily decrypt encrypted messages between client and server.

Tenda AC7 SetRebootTimer formSetRebootTimer stack-based overflow

A vulnerability was found in Tenda AC7 15.03.06.44. It has been declared as critical. Affected by this vulnerability is the function formSetRebootTimer of the file /goform/SetRebootTimer. The manipulation of the argument reboot_time leads to stack-based buffer overflow. The attack can be launched remotely. The exploit has been disclosed to the public and may be used.
