Certain Technicolor devices have an SNMP access-control bypass possibly involving an ISP customization in some cases. The Technicolor (formerly Cisco) DPC3928SL with firmware D3928SL-P15-13-A386-c3420r55105-160127a could be reached by any SNMP community string from the Internet; also you can write in the MIB because it provides write properties aka Stringbleed.
