Description

A pre-authentication OS command injection vulnerability has been identified in Omada gateways configured to operate as an OpenVPN Server due to insufficient validation of client-supplied data during OpenVPN connection establishment. An unauthenticated remote attacker may provide specially crafted input influencing backend command execution logic before authentication completes. Exploitation requires the OpenVPN Server feature to be enabled, VPN service reachable by the attacker and attacker to be able to initiate an OpenVPN connection attempt. Successful exploitation may allow arbitrary command execution, potentially leading to full compromise of the affected device.

• CWE-78Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component.
