Linksys WAG200G through 1.01.06 Admin Password Change Without Current Password

Summary

Linksys WAG200G through 1.01.06 contains a weak password change mechanism that allows attackers to change the administrator password without supplying the current password. Attackers with access to an authenticated administrator browser session can set a new password to lock out the legitimate administrator and take persistent device control.

Remediation

1. Inventory every Linksys WAG200G deployment, including staging.
2. No fixed version appears in the public sources yet. Check the references below and the vendor directly.
