Description

Overview

There is a vulnerability in the Beck IPC@CHIP that may allow an attacker to gain access to the device.

Description

The Beck IPC@CHIP is a single chip embedded webserver. This device contains a telnet server that "leaks information". That is, when an attacker connects to the telnet daemon and enters a valid username, the telnet daemon will prompt the user with "Password". However, if the attacker supplies the telnet daemon with an invalid account name, the device will respond with "User Unknown". Additionally, the telnet daemon permits unlimited login attempts and it isn't counting or logging any bad passwords. Given this, an attacker could make use of a brute-force password attack and gain entry to the device.


Impact

An attacker can connect to the telnet service and make use of a brute-force password attack and perhaps gain entry to the device.


Solution

Obtain a patch from the vendor.
