The RCA Digital Cable Modems DCM225 and DCM225E allow remote attackers to cause a denial of service (modem device reset) by connecting to port 80 on the 10.0.0.0/8 device.
RCA Digital Cable Modem DCM225 and DCM225E, and other modems that must conform to the Data-over-Cable Service Interface Specifications DOCSIS standard, uses the "public" community string for SNMP access, which allows remote attackers to read or write MIB information.
