Hidden CLI Function Escape in WAGO Managed Switches
CVE-2026-3587 is a critical vulnerability in multiple WAGO Lean Managed Switch and Industrial Managed Switch products. The issue is caused by hidden functionality in the device CLI prompt that can be abused by an unauthenticated remote attacker to escape the intended restricted management interface. According to the provided context, successful exploitation allows the attacker to break out of the restricted CLI environment, gain root access to the underlying Linux-based operating system, and fully compromise the device. The vulnerability is remotely reachable over the network and requires no authentication or user interaction.
