Predictable Default WPA2-PSK in Belkin Wireless Routers

IdentifiersCVE-2012-4366CWE-330

Belkin Surf N150 F7D1301v1, N900 F9K1104v1, N450 F9K1105V2, and N300 F7D2301v1 wireless routers generate their default WPA2-PSK passphrase predictably from eight digits of the WAN MAC address. An attacker can derive the default wireless passphrase after obtaining the relevant MAC-address information from beacon frames.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

An unauthenticated remote attacker can obtain the default WPA2-PSK and gain access to the affected wireless network.

Mitigation

If you can’t patch tonight, do this now.

Users should manually set a strong, unique WPA2-PSK passphrase and avoid using the default credentials. Network administrators should monitor for unauthorized devices and consider disabling SSID broadcast or using additional network segmentation where possible.

Remediation

Patch, then assume compromise.

Change the default WPA2-PSK passphrase to a strong, unique value immediately after setup. Belkin should release firmware updates to randomize the default passphrase generation process and prevent derivation from MAC addresses.
