TITLE

Ragentek Android OTA update mechanism vulnerable to MITM attack

Trust: 0.8

sources: CERT/CC: VU#624539

DESCRIPTION

Android devices with code from Ragentek contain a privileged binary that performs over-the-air (OTA) update checks. Additionally, there are multiple techniques used to hide the execution of this binary. This behavior could be described as a rootkit. This binary, which resides as /system/bin/debugs, runs with root privileges and does not communicate over an encrypted channel. The binary has been shown to communicate with three hosts via HTTP: oyag[.]lhzbdvm[.]com oyag[.]prugskh[.]net oyag[.]prugskh[.]com Server responses to requests sent by the debugs binary include functionalities to execute arbitrary commands as root, install applications, or update configurations. Examples of a request sent by the client binary: POST /pagt/agent?data={"name":"c_regist","details":{...}} HTTP/1. 1 Host: 114.80.68.223 Connection: Close An example response from the server could be: HTTP/1.1 200 OK {"code": "01", "name": "push_commands", "details": {"server_id": "1" , "title": "Test Command", "comments": "Test", "commands": "touch /tmp/test"}} This binary is reported to be present in the following devices: BLU Studio G BLU Studio G Plus BLU Studio 6.0 HD BLU Studio X BLU Studio X Plus BLU Studio C HD Infinix Hot X507 Infinix Hot 2 X510 Infinix Zero X506 Infinix Zero 2 X509 DOOGEE Voyager 2 DG310 LEAGOO Lead 5 LEAGOO Lead 6 LEAGOO Lead 3i LEAGOO Lead 2S LEAGOO Alfa 6 IKU Colorful K45i Beeline Pro 2 XOLO Cube 5.0. This program HTTP Via the next 3 Communicate with one host. 1 * Host: 114.80.68.223 * Connection: Close Example response from the server: * HTTP/1.1 200 OK * {"code": "01", "name": "push_commands", "details": {"server_id": "1" , * "title": "Test Command", "comments": "Test", "commands": "touch /tmp/test"}}Middle man (man-in-the-middle) By attack root An arbitrary command may be executed with authority. Multiple Android products are prone to a security-bypass vulnerability. Successfully exploiting this issue may allow attackers to bypass certain security restrictions and execute arbitrary commands as root by conducting a man-in-the-middle attack. This may lead to other attacks. Ragentek BLU Studio G etc. are smartphones
