openvpn-monitor is a web based OpenVPN monitor, that shows current connection information, such as users, location and data transferred.

Affected versions of this package are vulnerable to Access Restriction Bypass. When the openvpn-monitor application is accessed, the disconnect button is not displayed (as expected). However, there is no authorization check implemented which check if the functionality is allowed to be used or not. An attacker can use this to disconnect arbitrary clients.
