Because the component in question is accessed via the USB interface, the most probable attack vector involves a local attacker or one with physical access to the device, who can supply a malicious usbPartitionName value. Such an attacker can run arbitrary commands, effectively gaining full control of the router\u2019s operating system."}}}}, "created": "2026-03-03T08:46:32.054773+00:00", "title": "Critical Command Injection via USB Partition Parameter in Tenda W20E Router", "updated": "2026-04-16T15:00:14.304010+00:00", "vendors": ["tenda", "tenda$PRODUCT$w20e"]}
