3com OfficeConnect Remote 812 ADSL Router 1.1.7 does not properly clear memory from DHCP responses, which allows remote attackers to identify the contents of previous HTTP requests by sniffing DHCP packets.

Security readout for executives and security teams

This is an information disclosure issue in a legacy 3Com OfficeConnect Remote 812 ADSL Router firmware version 1.1.7. DHCP responses may contain leftover memory, potentially exposing contents of earlier HTTP requests to someone able to observe those DHCP packets. Exposure is most likely limited to environments still running the named legacy 3Com router and firmware. The bundle does not identify other affected products, supported versions, internet-scale exposure, or hosted services. Treat this as a legacy exposure review rather than an emergency unless affected devices are still deployed. Priority should rise if the router handles sensitive HTTP traffic or sits on a network segment reachable by untrusted users. Mitigation focus: Inventory for 3Com OfficeConnect Remote 812 ADSL Router firmware 1.1.7.; Check vendor or archival guidance for firmware updates or retirement options.; Replace affected legacy routers where exposure is confirmed..
