Security Vulnerabilities - CVEs Published In May 2023
Teltonika’s Remote Management System versions prior to 4.10.0 contain a virtual private network (VPN) hub feature for cross-device communication that uses OpenVPN. It connects new devices in a manner that allows the new device to communicate with all Teltonika devices connected to the VPN. The OpenVPN server also allows users to route through it. An attacker could route a connection to a remote server through the OpenVPN server, enabling them to scan and access data from other Teltonika devices connected to the VPN.

Version 00.07.03.4 and prior of Teltonika’s RUT router firmware contain a packet dump utility that contains proper validation for filter parameters. However, variables for validation checks are stored in an external configuration file. An authenticated attacker could use an exposed UCI configuration utility to change these variables and enable malicious parameters in the dump utility, which could result in arbitrary code execution.

Versions 00.07.00 through 00.07.03 of Teltonika’s RUT router firmware contain an operating system (OS) command injection vulnerability in a Lua service. An attacker could exploit a parameter in the vulnerable function that calls a user-provided package name by instead providing a package with a malicious name that contains an OS command injection payload.

An issue was discovered in KaiOS 3.0 and 3.1. The binary /system/kaios/api-daemon exposes a local web server on *.localhost with subdomains for each installed applications, e.g., myapp.localhost. An attacker can make fetch requests to api-deamon to determine if a given app is installed and read the manifest.webmanifest contents, including the app version.

An issue was discovered in KaiOS 3.0 before 3.1. The /system/bin/tctweb_server binary exposes a local web server that responds to GET and POST requests on port 2929. The server accepts arbitrary Bash commands and executes them as root. Because it is not permission or context restricted and returns proper CORS headers, it's accessible to all websites via the browser. At a bare minimum, this allows an attacker to retrieve a list of the user's installed apps, notifications, and downloads. It also allows an attacker to delete local files and modify system properties including the boolean persist.moz.killswitch property (which would render the device inoperable). This vulnerability is partially mitigated by SELinux which prevents reads, writes, or modifications to files or permissions within protected partitions.

Teltonika’s Remote Management System versions 4.14.0 is vulnerable to an unauthorized attacker registering previously unregistered devices through the RMS platform. If the user has not disabled the "RMS management feature" enabled by default, then an attacker could register that device to themselves. This could enable the attacker to perform different operations on the user's devices, including remote code execution with 'root' privileges (using the 'Task Manager' feature on RMS).

Teltonika’s Remote Management System versions prior to 4.10.0 contain a cross-site scripting (XSS) vulnerability in the main page of the web interface. An attacker with the MAC address and serial number of a connected device could send a maliciously crafted JSON file with an HTML object to trigger the vulnerability. This could allow the attacker to execute scripts in the account context and obtain remote code execution on managed devices.

Teltonika’s Remote Management System versions prior to 4.10.0 have a feature allowing users to access managed devices’ local secure shell (SSH)/web management services over the cloud proxy. A user can request a web proxy and obtain a URL in the Remote Management System cloud subdomain. This URL could be shared with others without Remote Management System authentication . An attacker could exploit this vulnerability to create a malicious webpage that uses a trusted and certified domain. An attacker could initiate a reverse shell when a victim connects to the malicious webpage, achieving remote code execution on the victim device.

Improper Privilege Management Vulnerabilities in Apache Software Foundation Apache InLong.This issue affects Apache InLong: from 1.2.0 through 1.6.0. When the attacker has access to a valid (but unprivileged) account, the exploit can be executed using Burp Suite by sending a login
request and following it with a subsequent HTTP request
using the returned cookie.
Users are advised to upgrade to Apache InLong's 1.7.0 or cherry-pick https://github.com/apache/inlong/pull/7836 https://github.com/apache/inlong/pull/7836 to solve it.
