Security readout for executives and security teams
CVE-2004-0476 is an old denial-of-service flaw in the 3Com OfficeConnect Remote 812 ADSL Router. A remote attacker who can reach the router's Telnet service may be able to crash or disrupt it with malformed Telnet input, causing reboot or packet loss. Exposure is most likely in legacy environments still running 3Com OfficeConnect Remote 812 ADSL Router 1.1.9.4 with Telnet reachable from untrusted networks. Treat this as a legacy exposure issue. It is not presented as actively exploited, but an exposed Telnet management interface on an old edge router can create avoidable outage risk. Mitigation focus: Identify any 3Com OfficeConnect Remote 812 ADSL Router devices still in service.; Check vendor or maintainer guidance for firmware updates or retirement recommendations.; Disable Telnet management if supported by the device..
