AI-Generated

Omada gateways configured as OpenVPN Servers are vulnerable due to a pre-authentication OS command injection flaw that arises from inadequate validation of client-supplied data. An unauthenticated remote attacker can exploit this vulnerability to execute arbitrary commands, potentially leading to complete device compromise. Organizations utilizing these gateways with the OpenVPN Server feature enabled should prioritize immediate remediation to mitigate the risk of exploitation.

Original NVD 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.
