description

Linksys E5350 firmware 1.0.00.037 has an authentication weakness in a Setup Wizard settings-saving function. A remote attacker may perform the affected settings operation without first logging in when the interface is reachable.

mitigation

Restrict access to the router's administration and setup interfaces to trusted management networks, and disable remote administration where possible. Monitor for and install a vendor firmware update that addresses the issue when one is released.
