Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: Command Injection via BLE. ๐ **Consequences**: Full device compromise. Attackers can execute arbitrary commands on ECOVACS robot vacuums and lawnmowers. ๐ฅ **Impact**: High severity (CVSS 9.8).โฆ
๐ก๏ธ **CWE**: CWE-77 (Command Injection). ๐ **Flaw**: The `SetNetPin` command is vulnerable. It fails to sanitize inputs properly when received via Bluetooth Low Energy (BLE).โฆ
๐ **Check**: Scan for ECOVACS BLE services. ๐ก **Test**: Attempt to connect via BLE without authentication. ๐ ๏ธ **Tool**: Use BLE sniffers or custom scripts to send `SetNetPin` payloads.โฆ
๐ซ **Workaround**: Disable BLE if possible. ๐ต **Physical**: Keep robots out of public/proximity range. ๐ **Network**: Isolate IoT devices on a separate VLAN. ๐ต **Power**: Turn off when not in use.โฆ
