OpenVPN 2.5.x < 2.5.10, 2.6.x < 2.6.10 Multiple Vulnerabilities (Windows)

critical Nessus Plugin ID 205311

Language:

Synopsis

An application on the remote Windows host is affected by multiple vulnerabilities.

Description

According to its self-reported version number, the version of OpenVPN installed on the remote Windows host is affected by multiple vulnerabilities:

- OpenVPN plug-ins on Windows with OpenVPN 2.6.9 and earlier could be loaded from any directory, which allows an attacker to load an arbitrary plug-in which can be used to interact with the privileged OpenVPN interactive service. (CVE-2024-27903)

 - The interactive service in OpenVPN 2.6.9 and earlier allows the OpenVPN service pipe to be accessed remotely, which allows a remote attacker to interact with the privileged OpenVPN interactive service. (CVE-2024-24974)

 - The interactive service in OpenVPN 2.6.9 and earlier allows an attacker to send data causing a stack overflow which can be used to execute arbitrary code with more privileges. (CVE-2024-27459)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to OpenVPN 2.5.10, 2.6.10 or later.
