An issue was found on TRENDnet TEW-831DR 1.0 601.130.1.1356 devices. The default pre-shared key for the Wi-Fi networks is the same for every router except for the last four digits. The device default pre-shared key for both 2.4 GHz and 5 GHz networks can be guessed or brute-forced by an attacker within range of the Wi-Fi network.
An issue was found on TRENDnet TEW-831DR 1.0 601.130.1.1356 devices. The network pre-shared key field on the web interface is vulnerable to XSS. An attacker can use a simple XSS payload to crash the basic.config page of the web interface.
An issue was found on TRENDnet TEW-831DR 1.0 601.130.1.1356 devices. The web interface is vulnerable to CSRF. An attacker can change the pre-shared key of the Wi-Fi router if the interface's IP address is known.
An issue was found on TRENDnet TEW-831DR 1.0 601.130.1.1356 devices. The username and password setup for the web interface does not require entering the existing password. A malicious user can change the username and password of the interface.
An issue was found on TRENDnet TEW-831DR 1.0 601.130.1.1356 devices. An OS injection vulnerability exists within the web interface, allowing an attacker with valid credentials to execute arbitrary shell commands.
The TRENDnet TI-PG1284i switch(hw v2.0R) prior to version 2.0.2.S0 suffers from an integer underflow vulnerability. This vulnerability exists in its lldp related component. Due to lack of proper validation on length field of PortID TLV, by sending a crafted lldp packet to the device, integer underflow would occur and the negative number will be passed to memcpy() later, which may cause buffer overflow or invalid memory access.
