Arista Networks has issued patches for CVE-2026-93952, a maximum-severity flaw in on-premises deployments of VeloCloud Orchestrator, the centralized management platform for VeloCloud SD-WANs. The bug, an improper input validation issue affecting setups using certificate-based authentication between edge devices and the orchestrator, lets remote attackers gain privileged internal access without credentials or user interaction, and Arista says it is already being exploited in the wild.
Most routers include a USB port that goes largely unused, but manufacturers like TP-Link and Asus support turning it into a shared file server, printer connection, or even a backup internet source via cellular dongle or phone tethering. Enabling these features requires digging into router settings for options like USB storage, media sharing, or printer sharing, with setup steps varying by brand and model.
A tech explainer clarifies the difference between a router's WAN port, which connects to a modem or ONT for internet access, and its LAN ports, which link wired devices like PCs, consoles, TVs and NAS units inside the home. It notes that combo router/modem units skip the WAN port entirely, while some routers use flexible WAN/LAN or auto-sensing ports instead of clearly labeled ones.
Most routers include a single WAN port alongside multiple LAN ports, and although the connectors look identical, they perform very different jobs. The WAN port links your router to the internet, while LAN ports connect local devices like PCs, TVs and consoles so they can talk to each other and share that connection.
