Linksys EtherFast Cable/DSL BEFSR11, BEFSR41 and BEFSRU31 with the firmware 1.42.7 upgrade installed opens TCP port 5678 for remote administration even when the "Block WAN" and "Remote Admin" options are disabled, which allows remote attackers to gain access.

Security readout for executives and security teams

Some Linksys EtherFast Cable/DSL routers running firmware 1.42.7 may expose remote administration on TCP port 5678 even when administrators believe WAN blocking and remote admin are disabled. If reachable from the internet, an attacker could access the router administration surface. Exposure is most likely in legacy small-office or edge-router environments still using the named Linksys models on firmware 1.42.7 with WAN reachability to TCP/5678. Treat as urgent if any affected router is internet-facing. The business risk is unauthorized access to perimeter network equipment, but applicability may be limited to old hardware still in service. Mitigation focus: Identify any BEFSR11, BEFSR41, or BEFSRU31 routers in inventory.; Confirm whether firmware 1.42.7 is installed on those devices.; Check current vendor guidance for supported firmware or replacement direction..
