CVE-2023-32348

22.05.2023, 16:15

Teltonikas 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.
