The 3Com 3CRWER100-75 router with 1.2.10ww software, when enabling an optional virtual server, configures this server to accept all source IP addresses on the external (Internet) interface unless the user selects other options, which might expose the router to unintended incoming traffic from remote attackers, as demonstrated by setting up a virtual server on port 80, which allows remote attackers to access the web management interface.

Security readout for executives and security teams

This issue can make a 3Com 3CRWER100-75 router accept unexpected inbound Internet traffic when an optional virtual server is enabled. In the cited example, port 80 exposure could make the router’s web management interface reachable remotely. Exposure is most likely where this legacy router model runs software 1.2.10ww and has virtual-server or port-forwarding features enabled on externally reachable ports. Treat this as a targeted legacy-network cleanup item. It is not cited as actively exploited, but exposed router administration can create a direct path into network control if still deployed. Mitigation focus: Disable virtual-server rules that expose router management services externally.; Restrict any required virtual-server rule to trusted source IP addresses only.; Confirm remote administration is disabled unless explicitly required..
