![]() OpenVPN is configured to not allow direct communication between Test Agents in the OpenVPN application itself, and routing is normally not enabled on the server running the CC application. Firewall rules exists to limit communication from TA's to the CC to specific services only. TA's are assigned an internal IP address in the 100.70.0.0/16 range. The Test Agents (TA) Appliance connects to the Control Center (CC) using OpenVPN. 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.Īn Improper Restriction of Communication Channel to Intended Endpoints vulnerability in the timescaledb feature of Juniper Networks Paragon Active Assurance (PAA) (Formerly Netrounds) allows an attacker to bypass existing firewall rules and limitations used to restrict internal communcations. The OpenVPN server also allows users to route through it. It connects new devices in a manner that allows the new device to communicate with all Teltonika devices connected to the VPN. 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. The token is then left in the browser history or access logs, potentially allowing attackers to bypass authentication via session replay. GL.iNET GL-AR750S-Ext firmware v3.215 inserts the admin authentication token into a GET request when the OpenVPN Server config file is downloaded. An attacker could set up a local OpenVPN server and push a malicious script onto the TBox host to acquire root privileges. The affected TBox RTUs run OpenVPN with root privileges and can run user defined configuration scripts. ![]() An authenticated remote attacker can exploit the exported OpenVPN configuration to execute an externally-controlled format string attack, resulting in sensitivity information leakage, or forcing the device to reset and permanent denial of service. In GL.iNET GL-AR300M routers with firmware v4.3.7 it is possible to write arbitrary files through a path traversal attack in the OpenVPN client file upload functionality.ĪSUS router RT-AX88U has a vulnerability of using externally controllable format strings within its Advanced Open VPN function. In GL.iNET GL-AR300M routers with firmware 3.216 it is possible to inject arbitrary shell commands through the OpenVPN client file upload functionality. Using the -fragment option in certain configuration setups OpenVPN version 2.6.0 to 2.6.6 allows an attacker to trigger a divide by zero behaviour which could cause an application crash, leading to a denial of service. Use after free in OpenVPN version 2.6.0 to 2.6.6 may lead to undefined behavoir, leaking memory buffers or remote execution when sending network buffers to a remote peer. ![]() The installer (aka openvpn-client-installer) in Securepoint SSL VPN Client before 2.0.40 allows local privilege escalation during installation or repair. ![]()
