VPN Server module in Linksys EtherFast BEFVP41 Cable/DSL VPN Router before 1.40.1 reduces the key lengths for keys that are supplied via manual key entry, which makes it easier for attackers to crack the keys.

Security readout for executives and security teams

This flaw affects the Linksys EtherFast BEFVP41 VPN router when using manual VPN keys. The VPN server shortened supplied keys, weakening the protection intended for encrypted VPN traffic. For a business, the main concern is confidentiality of legacy VPN tunnels, not broad internet takeover. Exposure is most likely in organizations still operating legacy Linksys BEFVP41 VPN routers with firmware earlier than 1.40.1 and manually configured VPN keys. Modern environments are unlikely to be affected unless old hardware remains in service. Treat this as a legacy-asset risk. It is not KEV-listed and has no cited active exploitation, but any remaining affected VPN device could weaken confidentiality for remote access or site-to-site traffic. Mitigation focus: Identify any Linksys BEFVP41 routers still in service.; Confirm firmware is 1.40.1 or later, using vendor guidance where available.; Replace unsupported legacy VPN hardware where firmware assurance is unavailable..
