The Internet of Things radios of Imperial Dabman comes with a vulnerability concerning a weak password which can easily allow a hacker from anywhere in the world in achieving root access. By the looks of it, the remote attacker is deeply embedded into the Linux BusyBox OS, which results in gaining control over several devices.
The adversaries have the potential in delivering malware by adding a radio which has already been compromised to a distinctive botnet. It can send the tailor-made audio streams to any device. The hacker can also listen to all the station messages and also uncover the password of the Wi-Fi for any other significant network where the radio is connected.
The issue is persisting on the undocumented Telnet service which connects with the Port 23 of the radio. The Telnet service utilizes several weak passwords alongside the hardcoded credentials. They can be cracked by using the utterly brute yet straightforward tactics. Moreover, from this point onwards the attacker can quickly gain unauthorized access with the OS and well as the radio.
At the time of testing, the researchers concluded that the compromisation of the password only took 10 minutes by utilizing ncrack automated script. Furthermore, this is happening because the pre-existing hardcoded password was named as "password." After the devices are logged onto the device, the researchers could access "etc," pathway alongside root privileges for requesting several contents of the flies.
By the looks of it, this also includes the complete password system which shadows the files or even a USB drive password. The service password of the httpd is set as Wi-Fi cfg with the unencrypted information present on the WLAN key. Vulnerability Lab namely, an advisory firm said that they had full access to a file system alongside httpd. Telnet can easily activate the protocol of the file transfer.
