CVE-2025-3540Public exploit

Authenticated command execution via getCapability POST handler

Published Apr 13, 2025 · Updated Apr 14, 2025

Command injection in four H3C Magic routers through V100R014 allows remote authenticated users to execute commands from the local network. The public record identifies FCGI_WizardProtoProcess as processing manipulated POST data at /api/wizard/getCapability but does not disclose the vulnerable parameter or exact command construction. Adjacent-network access and low privileges are required; successful exploitation can read or alter router data and interrupt service.
