CVEPublishedSeverityDetailsVector
CVE-2018-103812018-04-26 00:29:00HIGH (10)TunnelBear 3.2.0.6 for Windows suffers from a SYSTEM privilege escalation vulnerability through the "TunnelBearMaintenance" service. This service establishes a NetNamedPipe endpoint that allows arbitrary installed applications to connect and call publicly exposed methods. The "OpenVPNConnect" method accepts a server list argument that provides attacker control of the OpenVPN command line. An attacker can specify a dynamic library plugin that should run for every new VPN connection attempt. This plugin will execute code in the context of the SYSTEM user.NETWORK

Why keeping TunnelBear patched matters

Unpatched third-party applications are one of the most common ways attackers get in: 57% of breached MSP clients and 32% of ransomware cases trace back to a missing patch. Every TunnelBear release that fixes a security bug is public, so attackers see it too, and an out-of-date install becomes a documented way in. Tracking the installed version on every machine and closing the gap quickly is what turns a disclosed CVE into a non-event.
