Vulnerability Disclosure Timeline: ================================== 2018-06-01: Researcher Notification & Coordination (Security Researcher) 2018-06-02: Vendor Notification (Telestar Digital Data Security Department) 2018-06-07: Vendor Response/Feedback (Telestar Digital Data Security Department) 2018-08-30: Vendor Fix/Patch (Service Developer Team) 2019-09-08: Public Disclosure (Vulnerability Laboratory) Discovery Status: ================= Published Exploitation Technique: ======================= Remote Severity Level: =============== Critical Authentication Type: ==================== Pre auth - no privileges User Interaction: ================= No User Interaction Disclosure Type: ================ Coordinated Disclosure Technical Details & Description: ================================ 1.1 The dabman and imperial manufactured web radio series (typ d & i) suffers from a weak password vulnerability. The vulnerabilites allows local and remote attackers to compromise the web radios full embedded linux busybox os. The vulnerability is located within an undocumented telnet service (telnetd) of the linux busybox and is turned permanently on. The telnetd service uses weak passwords with hardcoded credentials on the local embedded linux busybox of the internet radio devices. The telnet password can be cracked by usage of simple manual password bruteforce technics or by basic automated attacks with scripts (exp. ncrack). After receiving the password the remote or local network attacker can unauthorized login to the internet radio device to use the embedded linux busybox operating system. After the attacker has been logged in as root user, he can open the /etc/ path to cat gshadow, shadow and the conf files. At the end the attacker has finally full root access on the busybox (telnetd), he can access the web-server (httpd) as admin and see the wireless lan + unencrypted key in ./flash/ - wifi.cfg. A demo exploit poc is available in the wild. The vulnerability allows local and remote attackers unauthorized and unauthenticated send commands to comprimise the web radio devices. The vulnerability is located httpd web-server communcation on port 80 and 8080. Local and remote attackers can send basic GET commands with basic command line tools (exp. curl or modhttp) to modify or manipulate http requests. The attacker can also capture the http airmusic commands to reverse engineer the radio device for unauthorized interactions. The system has no protection mechanism to block unauthorized transmit of commands. The web radio as well not owns an auth or reminder mechanism to ensure only allowed or trusted sources can transmit the commands (client, system, mac , auth ...).

The internet radio device auna IR-160 SE has multiple vulnerabilities. It uses the firmware UIProto, different versions of which can also be found in many other radios. The firmware offers a rudimentary web API that can be reached on the local network on port 80. This API is completely unauthenticated, allowing anyone to control the radio over the local network. (already known as CVE-2019-13474, but relevant for the other two findings) [1] [2] [3] 2. The web UI does not encode user input, resulting in a XSS vulnerability, e.g. The firmware crashes when sending a device name longer than 84 characters. Some parts of the firmware will recover afterwards and music will play again after a few seconds, but the service on port 80 remains borked until the radio is reset using the switch on the back. This may or may not be a memory corruption vulnerability. I don't feel like analyzing this any further, but it certainly looks kinda fucked. These reports also mention other devices that are possibly affected by this as well. Also, if anyone knows how to re-enable telnetd on the patched version of UIProto, please let me know!
