Title:

  • Atheros Driver Reserved Frame Vulnerability

Summary:

  • The wireless driver in some Wi-Fi access points (such as the
    ATHEROS-based Netgear WNDAP330) do not correctly parse malformed
    reserved management frames.

Assigned CVE:

  • CVE-2009-0052

Details:

  • The bug can be triggered by a malicious reserved management frame sent
    to the wireless access point (truncated packet). This can be achieved
    only after a successful 802.11 authentication (in "Open" mode according
    to the configuration of the wireless access point) and a successful
    802.11 association with appropriate security parameters (e.g. WPA w/
    TKIP unicast, TKIP multicast) which depends on the configuration of the
    wireless access point.

Attack Impact:

  • Denial-of-service (reboot or hang-up) and possibly remote arbitrary
    code execution

Attack Vector:

  • Unauthenticated wireless device for WPA/WPA2-PSK and EAP-based
    authenticated wireless device for WPA/WPA2-EAP

Timeline:

  • 2008-09-30 - Vulnerability reported Netgear
  • 2008-10-02 - PoC sent to Netgear
  • 2009-10-14 - Netgear released a patched firmware (3.0.3)
  • 2009-11-10 - Release of this security advisory

Affected Products:

  • Netgear WNDAP330 (firmware 2.1.11) with ATHEROS AR9160-BC1A chipset

Vulnerable Devices:

  • As it is a wireless driver specific issue, the wireless vendor should
    use the latest chipset wireless driver for their access point firmwares.
    This security vulnerability was reported to Netgear, updated firmwares
    should be available on their web site. Any other wireless device relying
    on this vulnerable wireless driver is likely to be vulnerable.
